Postoperative Pulmonary Hypertension

Pulmonary hypertension is persistent resistance after valve. Sometimes, the increased pulmonary pressure is only prominent during exercise 76. This masked pulmonary hypertension may be the cause for right ventricular failure and secondary tricuspid incompetence, which is a major cause of death after mitral valve replacement 28,29,77,78. Pulmonary pressure may also be elevated, or may increase when left ventricular function is poor or deteriorates. Cesnjevar concludes that intervention in patients with mitral valve replacement and pulmonary hypertension carries a higher (11 ) peri-operative mortality rate. However late survival rate is similar to primary replacement 78. They conclude that even in the presence of pulmonary hypertension the results of valve replacement are acceptable.

High Blood Pressure Hypertension

High blood pressure can cause many problems, such as heart disease kidney disease, and stroke. Fat people are especially likely to have high blood pressure. Signs of dangerously high blood pressure v f* All these problems may also be caused by other diseases. Therefore, if a person suspects he has high blood pressure, he should see a health worker and have his blood pressure measured WARNING High blood pressure at first causes no signs, and it should be lowered before danger signs develop. People who are overweight or suspect they might have high blood pressure should have their blood pressure checked regularly. For instructions on measuring blood pressure, see p. 410 and 411. What to do to prevent or care for high blood pressure

Difficulttotreat hypertension

Hypertension may be difficult to control because the blood pressure levels have been measured inaccurately, because the disease has progressed with time, because it is caused by another disease or medication, and or because the medication used is suboptimal. The patient may be taking too much sodium and or inadequate diuretics. Certain medications or diets may interfere with blood pressure medicines (Table 13.1) 2. One in ten individuals uses non-steroidal anti-inflammatory drugs (NSAIDs), and two meta-analyses have found that NSAIDs raise the blood pressure by an average of 3.3-5 mmHg in individuals with hypertension.18,19 Concomitant diseases can make high blood pressure difficult to control. Alcohol or cigarette abuse can worsen hypertensive control. Individuals with panic attacks or generalized anxiety disorder, pain disorders, or delirium, because of autonomic excess, may have difficult-to-control blood pressure levels. Approximately 40 of those with hypertension are obese.2...

Treatment of Hypertension

A systematic review of randomized trials comprising 48,000 hypertensive patients found that a sustained reduction of 5mmHg in diastolic blood pressure over a 3-year period was associated with a 38 reduction in the risk of late stroke (Collins and MacMahon, 1994). However, relatively few of these patients had a prior history of stroke or TIA. More recently, the Antithrombotic Trialists' Collaboration performed a review of the randomized trial data from 150,000 patients with cerebral or coronary events, and found that for every 5 mm Hg reduction in the diastolic blood pressure, there was a 15 relative reduction in the risk of stroke. Interestingly, there was no evidence of a lower diastolic threshold below which the risk of stroke did not fall. There remains some controversy over the threshold for therapeutic intervention in patients with hypertension. In the U.S., the recommendation is to maintain blood pressure less than 140 90 mm Hg, whereas in the U.K. the advice is for control to...

Hypertension and Hypotension

Significant, sustained hypotension is not usually a problem following endarterectomy and tends to respond well to colloid replacement. Early postoperative hypertension is more common and requires careful monitoring and control. As a rule, most anesthetists prefer to maintain blood pressure within 10 of preoperative levels. There is anecdotal evidence from reports documenting outcome for carotid surgery under locoregional anesthesia that postoperative hypertension is less of a problem. Most cases of early postoperative hypertension respond to a single bolus or carefully titrated infusion of beta-blocker (e.g. labetalol). Note that regular review is required as (quite often) the hypertension is a transient phenomenon and may require therapy only for 4 to 6 hours. Sustained postoperative hypertension at 3 to 5 days requires assessment by a cardiovascular physician. Caution should be exercised in discharging patients before blood pressure is adequately controlled, as these patients are...

Pulmonary hypertension

Pulmonary hypertension is a common association of many lung diseases. It also follows a number of non-pulmonary disorders, especially those of a cardiac nature. Pulmonary hypertension is defined as an increase in the pulmonary artery pressure (PAP) above 30 15 mmHg (mean PAP > 20-25 mmHg). Cor pulmonale refers to right ventricular hypertrophy and or dilatation secondary to pulmonary disease and in response to pulmonary hypertension. There may or may not be overt right ventricular failure. The development of right ventricular hypertrophy implies that the process is chronic. Right ventricular dilatation, however, may be acute. There are three groups of causes of pulmonary hypertension.

Renovascular Hypertension and Ischemic Nephropathy

Renovascular hypertension is a relatively uncommon cause of hypertension and is only seen in 5 to 10 of the hypertensive population. However, this translates to at least 600,000 people in the United States alone when considering that nearly 60 million people in the United States have some degree of hypertension. Renal artery stenosis (RAS) often produces an unclear clinical picture. Patients may be asymptomatic. However, they may also present with severe, uncontrolled hypertension referred to as reno-vascular hypertension or with evidence of renal insufficiency, otherwise known as ischemic nephropathy. This chapter focuses on the clinical characteristics that may be helpful in identifying those patients who may be at risk for RAS, how to accurately diagnose RAS, and how to correlate RAS with the symptoms of uncontrolled hypertension or ischemic nephropathy. It also outlines the options available for treatment, including medical management, endo-vascular correction of RAS via...

Hypertension

Hypertension is a well-recognized risk factor for atherosclerotic disease, particularly stroke and to a lesser extent ischemic heart disease and peripheral vascular disease. There are several possible mechanisms for the underlying potentiation of atherogenesis by hypertension, including direct mechanical disruptive effects, actions on vasoactive hormones, and changes in the response characteristics of the arterial wall. It is thought that, although hypertension may potentiate or enhance atherogenesis, hypertension alone is probably not sufficient for atherogenesis (Valentine et al., 1996).

Regular physical activity

Moderate levels of physical activity have significant effects on a woman's health. Burning approximately 150 kilocalories per day or 1000 kilocalories per week leads to a reduction in the risk of coronary heart disease by 50 and of hypertension, diabetes, and colon cancer by 30 .2 After adjusting for covariates such as age, smoking, alcohol use, history of hypertension, and history of high cholesterol, women who are regularly physically active are 50 less likely to develop type II diabetes (relative risk 0.54) than women who are not regularly active.8 Vasomotor and psychosomatic symptoms associated with menopause are also reduced with moderate amounts of activity.6,9 Examples of moderate levels of physical activity are depicted in Table 2.2.

Alternative therapies

T'ai chi practice improves mood states, range of motion, physical function, and hemodynamic parameters.32,42,43 Reductions in anger, total mood disturbance, tension, confusion, and depression and an increase in self-efficacy are evident after regular t'ai chi practice.32 Improvements in self-reported physical function and a reduction in falls is also reported.37,42,44 Patients suffering from acute myocardial infarction can reduce blood pressure after practicing t'ai chi.45 T'ai chi is an effective modality for improving several aspects of health.

Abdominal Aortic Aneurysm

A 59-year-old man presented with an abdominal aortic aneurysm (AAA) discovered on duplex scan examination of the abdomen. The AAA was 60-mm large and extended to the left common iliac artery. The patient was otherwise asymptomatic, with no abdominal or back pain. His medical history was significant for hypertension controlled by bitherapy, non-insulin-dependent diabetes diagnosed 5 years previously, claudication with a walking distance of 400 metres, and a smoking history of 40 packs year. He had no history of myocardial infarction (MI) or angina pectoris.

Of Lipidlowering Drugs that may Benefit PAD Patients

Statins increase nitric oxide (NO) production and improve endothelial function (e.g. increased flow-mediated dilatation). They have antioxidant properties and they inhibit the migration of macrophages and smooth muscle cell proliferation, leading to an antiproliferative effect and the stabilization of atherosclerotic plaques. Statins have anti-inflammatory effects including a reduction in the circulating levels of CRP, inflammatory and proinflammatory cytokines e.g. interleukin-6 (IL-6), IL-8 , adhesion molecules e.g. intercellular adhesion mol-ecule-1 (ICAM-1), vascular cellular adhesion molecule-1 (VCAM-1) and other acute phase proteins. They reduce tissue factor expression and platelet activity, whereas fi-brinolysis can be enhanced. Statins improve microalbu-minuria, renal function, hypertension and arterial wall stiffness. A significant reduction of the carotid and femoral intima-media thickness was also reported early after statin treatment. Patients with the metabolic syndrome...

Coronory Heart Disease

Hypertension The principal diet-related determinants of high blood pressure are obesity, high alcohol intake, high sodium intake, and low potassium intake.30,31 Most comparative studies have found that vegetarians are thinner and have a lower alcohol intake than non-vegetarians, and that they have a higher potassium intake, but there is no consistent evidence that vegetarians have a low sodium intake some vegetarian foods are high in sodium. A number of studies have examined the association of vegetarian diets with blood pressure. Some studies comparing groups of vegetarians and non-vegetarians found lower blood pressure in the vegetarians, but other studies found no difference.32 Randomized trials of the effects of vegetarian diets on blood pressure have shown reductions in blood pressure of around 5 mmHg that were not due to changes in sodium intake and did not appear to be explicable by changes in other relevant nutrients such as potassium.32 Subsequent trials have attempted to...

Ruptured Abdominal Aortic Aneurysm

A 70-year-old white male presents to the emergency department with sudden onset of severe back pain. The pain is described as severe and constant without alleviating or aggravating symptoms. He has never had pain like this before. He denies chest pain, shortness of breath, or loss of consciousness. He denies any history of an abdominal aortic aneurysm. His past medical history is significant for hypertension, and chronic obstructive pulmonary disease that requires home oxygen therapy. He had bilateral inguinal herniorrhaphy some years ago, but has never had a laparotomy.

Weight concerns Overweight and obesity

To lower blood pressure in overweight and obese persons with high blood pressure To improve plasma lipid levels in overweight and obese persons with dislipidemia To lower blood glucose levels in overweight and obese persons with type 2 diabetes Strong evidence supports an association between obesity and increased morbidity and mortality. Recent research has linked excessive weight and body fat to a dysmetabolic syndrome, which includes diabetes, hypertension, and coronary artery disease.11

Ischemic Brain Injury

Patients have survived due to improvement in the early management of head injury. The evidence is that ischemic brain damage occurs soon after injury.110 However, the pathogenesis of ischemic brain damage is not fully understood. In years before neurosurgical techniques improved, it was more common in patients who sustained a known clinical episode of hypoxia following head injury (blood pressure less than 30 mmHg for 15 min). It has also been found to be more common in patients who experience high intracerebral pressure.111 On the other hand, brain damage may occur without intracerebral pressure being high, and moreover, there is a statistically significant correlation between ischemic brain damage and the presence of cerebral arterial spasm.112,113 Modern neuro-surgical care has made us aware that some ischemic damage is avoidable by controlling factors such as obstruction of airway, providing appropriate control of epilepsy, relieving hypertension, and aggressively treating...

Thoracoabdominal Aortic Aneurysm

A 72-year-old white male presented to his primary-care physician with a history of left chest pain for the past month. The pain was dull and constant, and radiated to the back, medial to the scapula. He denied new cough or worsening shortness of breath. He had no recent weight loss, and his appetite was good. He has a history of hypertension that was currently controlled medically. He had a smoking history of 60 packs a year. In addition, he suffered a myocardial infarction (MI) 5 years ago. The patient denied any history of claudication, transient ischaemic attacks or stroke. He had undergone surgery in the past for bilateral inguinal hernias, and he underwent cardiac catheterisa-tion after his MI.

Evaluation Of The Severity Of Mr

Obviously, patients should not undergo valve surgery unless there is severe regurgitation. Non-invasive imaging can provide all the information needed to gauge the severity of MR left and right ventricular function, the cause and severity of MR, the presence of pulmonary hypertension and associated valve lesions as tricuspid regurgitation and aortic valve disease Cardiac catheterisation with exercise hemodynamics and angiography is only indicated when there is discrepancy between clinical and non-invasive findings. Although ventriculography has its own limitations11, it provides an additional method to assess chamber dilation and function and to estimate MR severity. Right heart catheterisation is only indicated when there is uncertainty about MR severity and pulmonary hypertension. Coronary angiography is indicated in patients with risk factors for coronary artery disease including age, hypercholesterolemia, and hypertension.

Unique High Risk Conditions Eisenmenger syndrome j

This condition is characterized by pulmonary hypertension and a bidirectional shunt. The normal decrease in systemic vascular resistance (SVR) in pregnancy places the patient at risk for having the pulmonary vascular resistance (PVR) exceed the SVR. When this develops, the path of least resistance for blood from the right heart is to bypass the pulmonary circulation across the shunt. This results in the left heart pumping unoxygenated blood into the systemic circulation, resulting in a 50 mortality risk. Management is by avoiding hypotension. months postpartum. Risk factors include advanced maternal age, multiparity, hypertension, and multiple pregnancy. Mortality rate is 75 if reversal does not occur within 6 months. Management is supportive, intensive care unit (ICU) care.

Prospects For Prevention Of Dementia

Vascular dementia presents the greatest scope for prevention, because there are a number of risk factors which are modifiable. Control of hypertension and smoking are the interventions most likely to be successful. There is evidence that stroke mortality in Australia is declining at around

Upper Limb Vascular Diseases

A rare cause of upper limb ischemia is Takayasu arteritis (pulseless disease), a condition most commonly seen in young female Asians. It is a granulomatous disease involving major arteries, in particular the aortic branches and pulmonary arteries. Clinically, the patient is systemically unwell with symptoms and signs of limb ischemia or renovascular hypertension. Radiological features suggestive of the condition are enhancing thickened arterial wall on CT, segmental stenotic or occlusive disease of major arteries, and aneurysm formations.

What are the physical consequences

Complications are conditions that arise as a result of having diabetes. Some are short term, for example hypoglycaemia (low blood glucose), hyperglycaemia (high blood glucose) and ketoacidosis (very high blood glucose). Others are more long term and develop gradually over time and include heart disease, high blood pressure, damage to the kidneys, and eye and nerve damage.

Dissection Stanford B

A 54-year-old woman was admitted to another hospital with the provisional diagnosis of a myocardial infarction (MI). She experienced a sudden chest pain. Some hours later, she developed paraesthesia in both legs, which improved spontaneously. Subsequently, she felt abdominal discomfort and developed diarrhoea and vomiting. The patient had been normotensive throughout her life, but now she required five different antihypertensive drugs to stabilise blood pressure. Some laboratory data were abnormal, including leucocytes, transaminases, lactic dehydrogenase and lactate. Duplex sonography and transoesophageal echocar-diography revealed an aortic dissection of the thoracic and abdominal aorta beginning distal to the left subclavian artery blood flow into the visceral arteries and the right renal artery was reduced. Contrast CT scans confirmed Stanford B aortic dissection.

Systemic Corticosteroids

Corticosteroids are potent modulators of the immune system but have low specificity and serious side effects. Their well-known and serious side effects, including osteopaenia, weight gain, hyperglycaemia, hypercholesterolaemia, hypertension, and skin fragility, can occur with modest doses administered over relatively short periods. Despite this they are widely used in solid organ transplantation, where their combination with other immunosuppressive agents enables the use of lower doses of the individual agents with a corresponding reduction in the side effects. However, even when used in combination, the side effects from systemic administration of

Of Systemic Immunosuppression

Overwhelming infection, skin and hair and oral changes, hypertension and nephrotoxicity can complicate cyclosporin usage. Antiprolifer-ative drugs such as azathioprine and mycophe-nolate can cause marrow suppression and gut problems and the therapeutic range is narrow so that side effects are relatively frequent.

Guillainbarre Syndrome

VS severe hypertension (BP 210 180) no fever. PE dense right sided hemiplegia funduscopic exam reveals presence of papilledema in addition to hypertensive retinopathy right-sided Babinski eyes deviated toward left no meningeal signs present. Bleeding is most often caused by hypertension. In the presence of moderate to severe hypertension, small penetrating arterioles may rupture deep within the brain, causing a hematoma that displaces brain structures. Common sites are the putamen, thalamus, pons, and cerebellum.

Vascular Risk Factor Modification in Peripheral Arterial Disease

Demia, (6) hypertension, (7) sedentary lifestyle, and (8) type A personality or stress. The literature suggests that cigarette smoking, hypertension, dyslipidemia, and diabetes mellitus are important factors in the development of PAD, and these will be addressed in turn (Table 6.2). A key risk factor for PAD is platelet aggregation along with other hemorheological factors such as increased plasma fibrinogen and decreased fibrinolysis. Currently an area of interest that is being explored is that of the contribution of inflammation to PAD. The high white blood count (WBC) contributes vascular risk to the patient with PAD (Belch et al., 1999) as does increased oxidative stress. Of the above, however, platelet activation and release in the patient with PAD has been well documented and has led to the evidence-based use of antiplatelet agents in PAD.

Peptic Ulcerperforated

Alcoholic hepatitis gives rise to fibrosis (cirrhosis) of the liver, which increases portal vein resistance. With the development of portal hypertension (> 10 mmHg), there are portal-systemic anastomoses formed such as the left gastric-azygous (esophageal varices), the superior-middle and inferior rectal veins < r>

Nonketotic Hyperosmolar Coma

HPI Very high blood pressure has been recorded at the time of previous paroxysms. The patient has a good appetite but looks cachectic blood pressure recorded between paroxysms is normal. The patient has no history suggestive of renal disease. PE VS hypertension (BP 180 120). PE hypertensive retinopathy changes on funduscopic exam.

Specific Discussion

The physical signs and CXR suggest emphysema. This is confirmed by an obstructive ventilatory impairment with hyperinflation, air trapping, and reduced diffusion. In bronchial asthma, there would typically be marked bronchodilator response, and the patient with chronic bronchitis would present with chronic sputum production. Tuberous sclerosis presents radiographically as hyperinflation and lower zone infiltrates, but clinically is a systemic disease with a clinical triad of mental retardation, seizure disorder, and dermal angiofibromas called adenoma sebaceum. Pulmonary disease is rare (it is seen in less than 1 of cases) and presents with pneumothoraces and hemoptysis. In this case with emphysema, complications include respiratory failure. Increased IgE levels are associated with allergic bronchial asthma obstructive sleep apnea and clubbing do not have an increased association with this condition. CT scan is the most sensitive imaging modality to...

Scorpion Venom Poisoning

Scorpion venoms have received much research attention in recent years as efforts to isolate the various components proceed. The venoms of scorpions posing a serious threat to human life possess toxins with significant neurologic and cardiovascular effects. These venoms stimulate massive release of neurotransmitters from autonomic nerve terminals, neuromuscular junctions, and the adrenal medulla, resulting in sympathetic, parasympathetic, and paralytic signs and symptoms.105,120 Pain is a common immediate symptom and may be enhanced by the presence of serotonin in many venoms.120 Paresthesias may occur as well. Systemic findings are related to venom-induced release of acetylcholine and catecholamines. Such findings may include restlessness, anxiety, roving eye movements, hypersalivation, diaphoresis, nausea, vomiting, hypertension, bradycardia, tachycardia, dysrhythmias, hyperthermia, muscle fasciculations, alternating opisthotonos and emprosthotonos, weakness, paralysis, difficulty...

B False Aneurysm in the Groin Following Coronary Angioplasty

A 70-year-old female with a history of hypertension developed chest pair and was admitted to a local hospital. Heparin was administered intravenously. Later that day, she underwent coronary angiography, which showed a critical stenosis of the left anterior descending artery. The lesion was treated with angioplasty and stent placement. The right femoral artery sheath was left in place overnight, and heparin was continued. The following morning after stopping heparin, the sheath was removed and a FemoStop device was placed over the groin for 4 h. Heparin was then restarted.

Sedentary Lifestyle Exercise Therapy

Intermittent claudication is a symptom of lower limb peripheral arterial disease. It arises when the blood flow is insufficient to meet the metabolic demands of the leg muscles in ambulating patients. Intermittent claudication is a leveraged disability, as pain increases with walking, patients walk shorter distances, muscle strength erodes, and walking distances continue to decrease. This leads to other negative consequences such as weight gain, hypertension, and diabetes. Overall, patients with claudication have a 60 lower functional capacity than age-matched individuals without the disease (Eldridge and Hossack, 1987).

Longterm complications

The possibility ofdeveloping long-term complications is one ofthe most frightening aspects of diabetes. Prolonged periods of high blood sugar increase the risk of complications in people with diabetes. Common ailments include cardiovascular disease (such as high blood pressure and atherosclerosis), eye disorders, kidney disease, nerve disorders, and foot and leg problems. Most of these conditions result from years of chronic high blood sugar levels. The good news is that many ofthe possible problems can be treated, and often the treatment is most effective when the complications are noticed at an early stage. This is why you will be asked to go for regular medical check-ups.

Anesthesia for Vascular Surgery

Patients with operative lower extremity peripheral vascular disease (PVD) have an even higher incidence of CAD. Hypertension, diabetes, and renal insufficiency are all more frequent in patients with PVD compared to the general population. Following aortic surgery, carotid endarterectomy, and lower extremity revascularization procedures, the most common major complication is a cardiac event. Anesthesia is a risk factor contributing to the perioperative morbidity and mortality of the vascular patient. The preoperative preparation and the intraoperative management can predict and influence the postoperative course. This chapter provides an overview of the various anesthetic techniques that can be used in patients presenting for vascular procedures.

Description of Xrays in This Chapter

This x-ray shows bilateral cystic-appearing opacities involving the lower and middle zones. These cysts have distinct walls and air-fluid levels. This picture is consistent with bilateral lower lobe and lingular bronchiectasis. Note the large pulmonary arteries, which may suggest secondary pulmonary hypertension and cor pulmonale.

Physiological and Mechanical Considerations

Aortic cross-clamping leads to an increase in cardiac afterload. This acute increase in after-load is both measurable and manipulable, directly and indirectly. Uncontrolled hypertension, although tolerated by the healthy heart, can lead to systolic or diastolic dysfunction and cardiac decompensation. Blood pressure is often viewed as dependent on circulating blood volume, cardiac preload and afterload, and cardiac function. All of these factors are influenced by, and essentially precluded by, the ability of the heart to withstand the stress of any acute physiologic change. The effects of aortic cross-clamping are initially mechanical due to abrupt change of afterload. The rough percent age of cardiac output blocked by clamping at various levels is as follows infrarenal, 10 to 15 suprarenal, 15 to 25 and supraceliac, 55 . The precise percentage varies with certain disease states, such as aortic occlusive disease and collateralization. Typically, the surgeon works in concert with the...

Dementia the Public Health Challenge

Promising pharmacological strategies, such as the use of anti-inflammatory drugs, estrogen and vitamin E also seem to offer some potential for prevention. But we must temper our enthusiasm until better data are available. Perhaps the most realistic and practical approach to prevention is for the vascular dementias, where we already possess the capability to alter vascular risk factors such as hypertension, diet, exercise, smoking and hyperlipidemias.

Recent Recommendations on Vitamins and Chronic Disease Prevention

American Heart Association (176) Vitamin or mineral substitutes are not a substitute for a balanced, nutritious diet that limits excess calories, saturated fat, trans fat, and dietary cholesterol. Scientific evidence does not suggest that consuming antioxidant vitamins can eliminate the need to reduce blood pressure, lower blood cholesterol level, or stop smoking.

The answer is b Fauci 14e p 1446 Kartagener syndrome is the

The answer is d. (Fauci, 14 e, pp 1466-1468.) Primary pulmonary hypertension (PPH) is of unknown etiology and primarily affects women in their thirties or forties. The underlying problem in the disorder is a fixed increased resistance to pulmonary blood flow. Pulmonary function in PPH is usually normal, but the elevation in pulmonary artery pressure causes a decrease in cardiac output and eventually right ventricular failure. Patients become dyspneic and hypoxemic due to the mismatch of pulmonary ventilation and perfusion and the reduced cardiac output. Physical examination reveals signs of right ventricular hypertrophy, right- and left-sided heart failure, and tricuspid and pulmonic regurgitation. The mean survival for this disease is 2-3 years from the time of diagnosis.

Dementia the Challenge for the Next Decade

The subclassification of dementia by categorical diagnosis has proved useful, as it has allowed internationally agreed consensus criteria for each diagnosis to be developed 2,3 . This has led to standardization in research methodology and international comparisons. However, the disadvantage of this system is its encouragement of clinicians to seek maximal points of difference between clinical cases, so that they may be clearly diagnosed. If two sub-diagnoses are thought to be present, then a diagnosis of mixed etiology has to be made. The separation of vascular from Alzheimer's dementia is the most common of these distinctions made in clinical practice. However, this distinction may no longer be valid. Evidence that a wide range of vascular risk factors and vascular disease itself is associated with the onset of Alzheimer's disease (AD) is growing 4 . Furthermore, post mortem examination of a consecutive sample of community-drawn cases on a dementia register indicated that mixed...

Postnatal Influences on Offspring

As would be expected, maternal diet is a primary determinant of milk composition. Cafeteria diets composed of highly palatable junk foods increase the long-chain and decrease the medium-chain fatty acid content of maternal milk and have an additive effect to the presence of maternal obesity in lowering the protein and raising the long-chain fatty acid content of milk (104). Diets high in polyunsaturated fatty acids have the effect of lowering pup body weight and adiposity and leptin levels (58). Feeding dams a high-fat diet also accelerates the onset of independent feeding in neonates by 1 to 2 days (116) in association with increased weight gain (117) and the development of hypertension and abnormal glucose homeostasis as adults (118). Furthermore, feeding successive generations of dams a high-fat diet leads to progressive increases the level of obesity of their offspring (119). This feed-forward effect may have important relevance to the increasing incidence of obesity in the...

General Complications

Stability of BP is frequently noted and can result in both hypertension and hypotension 18, 21 . The mechanism behind systemic hypertension during and after carotid artery manipulation seems to be transient dysfunction of adventitial baroreceptors in the end-arterectomized area 6 . Infiltration of local anaesthetic into the periadventitial tissue around the carotid sinus might abolish this response 3 . Release of metabolic factors such as renin, vasopressin and cranial norepineph-rine has also been described 2 . Sudden increases in CBF due to removal of a significant stenosis may also contribute to the hypertension. Postprocedural hypertension is a critical finding associated with hyperperfusion syndrome (HPS) or intracranial haemorrhage (ICH). This has been well described following CEA and is associated with significant morbidity and mortality. The incidence of HPS after CEA is < 3 , with symptoms such as irritability, seizure and confusion, and rarely progresses to ICH if treated...

How does diabetes affect your heart

When blood flow to the heart is slowed for a period of time, one result is a kind of chest pain called angina, and this is a warning signal that something is reducing the flow of blood to the heart. Two types of cardiovascular complications that can result from diabetes are hypertension (high blood pressure) and atherosclerosis (hardening ofthe arteries).

Guidelines For Exercise

The participants in this study were young white and black men and women (ages 1830) who completed treadmill testing and then were followed from 1985 to 2001. Glucose, lipids, and blood pressures were measured and physical activity was assessed by interview and self-reporting. Outcome measurements included hypercholesterolemia, metabolic syndrome, hypertension, and type-2 diabetes. 4. Hypertension 13. Patients with low fitness (< 20th percentile) were three to six times more likely to develop diabetes, hypertension, and metabolic syndrome than patients with higher fitness (> 60th percentile). Adjustment for BMI lowered the strength of the associations. Those patients that improved their fitness over 7 years reduced their risk of diabetes and metabolic syndrome.

Fibromuscular Dysplasia

Vascular bed, and it is likely that there will be subclinical disease present in other areas in most patients. The most common manifestations are hypertension from renovascular disease and stroke from carotid disease. In terms of the kidney, a significant proportion of renovascular disease arises on a background of FMD, the primary result of which is hypertension. However, as renovascular disease is a relatively uncommon cause of hypertension in itself, FMD is not a major contributing factor to adult hypertension. When it affects the cerebrovascular system, it is predominantly seen in the internal carotid artery, and frequently is seen bilaterally. Vertebral artery involvement also occurs, although rarely in isolation from carotid disease. There is also a reported association between cerebrovascular FMD and intracranial berry aneurysms of an order of around 7 . The symptoms of cerebrovascular disease depend on the location and severity of the lesions. Therapeutic intervention in FMD...

Lower Limb Claudication due to Iliac Artery Occlusive Disease

A 63-year-old hypertensive man presented in 1990 with a history of pain developing in his left calf and thigh after walking 100 metres. During the preceding 3 months, following the introduction of a beta-blocker for newly diagnosed hypertension, the distance he could walk at a normal pace had reduced from 200 metres. The pain ceased almost immediately after stopping walking and appeared again after the same interval. A systemic enquiry was unremarkable. He was noted to be an active and life-long heavy smoker. Clinical examination revealed a diminished left femoral pulse and absent left popliteal and pedal pulses. The abdominal aorta and right leg pulses were normal. No bruits were audible in the abdomen or groins.

The answer is c Seidel 4e pp 476478 Coarctation of the aorta

Is narrowing of the aorta usually just distal to the origin of the ductus arte-riosus and subclavian artery. Patients may complain of epistaxis, headache, cold peripheral extremities, and claudication. Absent, delayed, or markedly diminished femoral pulses may also be found. The low arterial pressure in the legs in the face of hypertension in the arm is also a clue toward the diagnosis. Chest radiograph in coarctation shows rib-notching secondary to the dilated collateral arteries. PDA is associated with a loud, continuous murmur. Tetralogy of Fallot consists of VSD, pulmonic stenosis (PS), dextroposition of the aorta, and right ventricular hypertrophy (RVH).

Antidepressants for Better Quality of Life

Whereas first generation antidepressants (tricyclics and MAO inhibitors) were associated with burdensome side effects, the class of selective serotonin reuptake inhibitors (SSRIs) first exhibited a favourable side-effect profile, which opened the way for effective pharmacotherapy for the necessary long-term treatment in depression (see 2 for a review). Since depression should be considered as a lifelong disorder, in the same way as hypertension or diabetes mellitus, the SSRIs revolutionized treatment, in the sense that antidepressants could be used in the necessary dosage for long-term treatment. Contrastingly, patients were not willing to take first generation antidepressants in the right dosage for much longer than the acute phase and therefore exposed themselves to a higher risk of relapse. Fortunately the same successful strategy, a favourable side-effect profile, has been followed for the antidepressants introduced after the SSRIs.

Aorta occurs when the intima is interrupted so that blood enters the wall of the aorta and separates its layers, forming a second lumen. It is almost always fatal if left undiagnosed, but with prompt treatment most patients survive. Anything that weakens the media can lead to dissection, but hypertension is the most common risk factor. Aortic dissection is a major cause of morbidity and mortality in Marfan syndrome. Other etiologies of dissection include cystic medial necrosis (described in patients with bicuspid aortic valves), syphilis, Ehlers-Danlos syndrome, trauma, and bacterial infections. Patients often have murmurs due to aortic insufficiency. The treatment of dissection is to control the blood pressure and heart rate to prevent extension of the dissection. A tracheal tug is considered positive if the pulsating aorta is felt when the trachea is pulled upward.

Toxoplasma infection in immunocompromised hosts

Therapy is often started empirically, and response is expected within 14 days. If no response is seen, then brain biopsy is required for diagnosis. Corticosteroids are often used to control intracranial hypertension due to mass effect. Desensitization to sulfadiazine has been reported to be successful. In about 30 percent of patients relapse of encephalitis occurs when treatment is stopped, although relapse may take several weeks. Patients are therefore maintained on pyrimethamine 25 mg d, sulfadiazine 4 g d, and folinic acid 10 mg d, after they have completed a 6-8-week course of primary treatment. With the use of antiretroviral therapy, if the CD4+ lymphocyte count is restored to over 200, secondary prophylaxis can be discontinued.

The answer is b Seidel 4e p 481 An acquired arteriovenous

(increases venous return and decreases thoracic pressure) increases the split of S2 by two mechanisms. First, there is delayed pulmonic valve closure, which is due to prolonged right ventricular ejection time from increased stroke volume. Second, inspiration increases the compliance of the pulmonary vasculature and thereby decreases the return of blood to the left heart and shortens its ejection time by the same mechanism. Pulmonary hypertension and systemic hypertension cause a loud S2 calcific AS causes a soft S2.

Bypass to the Popliteal Artery

A 62-year-old overweight postal worker presented with complaints of cramps in his right calf. He stated that this reproducible pain occurred each time he walked 50 yards and resolved upon sitting down. He denied tissue loss or rest pain. His past medical history was significant for hypertension, hypercholesterolemia and tobacco use, as well as coronary revascularization.

The answers are 180a e f 181d 182b c Seidel 4e p 429 Normally S2 is split during inspiration Wide splitting of S2 occurs

The answers are 185-a, 186-i, 187-l, 188-k. (Fauci, 14 e, pp 1303-1304, 1317, 1330.) Patients with AS may present with symptoms of angina, syncope, dyspnea, or congestive heart failure. The etiologies of AS include rheumatic fever and congenital bicuspid valve. Idiopathic calcific AS is a common disorder in the elderly and may produce the murmur of AS, but it is usually a mild disorder and of no significance. Hyper-trophic obstructive cardiomyopathy (HOCM or HCM) is the most common cause of sudden cardiac death in young adults. Patients may be asymptomatic, and over half have a positive family history of sudden death. ASD is a common anomaly in adults VSD may be a congenital anomaly or a complication of myocardial infraction. Both defects may cause a left-to-right shunt, which may lead to pulmonary hypertension (loud S

Wine and the heart is wine more cardioprotective than ethanol

The hypothesis that wine protects against heart disease was originally proposed to explain the comparatively low mortality from coronary heart disease in France despite relatively high levels of known coronary risk factors, such as smoking, high blood pressure, cholesterol, fat intake or obesity (the 'French paradox'). One proposed explanation was that the low rates of coronary heart disease are due to a high intake of wine (particularly red wine, which contains various substances with possible cardioprotective effects). Several studies based on international data on mortality rates and alcohol (wine) intake have supported this interpretation. Mortality from coronary heart disease was, in general, lower in countries with higher per capita intakes of alcohol, and the link with alcohol appears stronger for wine intake than for alcohol (ethanol) in general or for other beverages (LaPorte et al. 1980 Criqui and Ringel 1994 Leger et al. 2002).

The Renin AngiotensinCardionatrine System

Not the main pathway, for angiotensin II stimulates the adrenal cortex to secrete aldosterone. The latter acts on the kidneys enhancing sodium reabsorption, water retention and its consequent increase in extracellular volume ECV, which has also a compensatory effect on BP. This is a second negative feedback loop. The atria, in turn, have stretch volume receptors that activate the secretion of the atrial natriuretic peptide or car-dionatrine. Surprisingly, the heart appears also as an endocrine organ. This relatively new substance stimulates the kidneys to excrete sodium (natriuresis), opposite to sodium reabsorption. Besides, it has a vasodilat-ing effect, thus, tending to lower BP (Wardener and Clarkson, 1985). Natriuretic peptides are a group of naturally occurring substances that act in the body to oppose the activity of the renin-angiotensin system. Heart failure is a leading cause of morbidity and mortality. In the United States, there are more than 5 million patients with heart...

Chapter Summary continued

Pulmonary hypertension is increased pulmonary artery pressure, usually due to increased vascular resistance or blood flow. Pulmonary hypertension can be idiopathic or related to underlying COPD, interstitial disease, pulmonary emboli, mitral stenosis, left heart failure, and congenital heart disease with left to right shunt.

Morbidity and Mortality Associated With Obesity

Many previous analyses, however, used older data sets obtained at a time when the screening and treatment of cardiovascular disease risk factors and diabetes were less aggressive than is currently the case. In a recent controversial analysis, Flegal et al. used NHANES data to make new estimates of excess deaths associated with underweight, overweight, and obesity (5). This analysis did not correct for the presence of comorbid conditions such as treated hypertension or treated hyperlipidemia. The results demonstrated that those with a BMI between 25 and 30 had a lower mortality rate than those with either a lower or higher BMI. Those with a BMI greater than 35 clearly had increased mortality. It appeared that the increased risk of mortality associated with obesity was higher in earlier cohorts, suggesting that current treatments for comorbid conditions may be improving the health of obese people. In a related study, Gregg et al. examined longitudinal trends in the management of...

Mitral Valve Stenosis

Generally, rheumatic heart disease is the major cause of patients with mitral stenosis. Approximately 40 of these patients present with isolated valve stenosis 40. With the advent of percutaneous mitral balloon valvulotomy, a technique is available with immediate 31 and long-term 3 similar to those of open commissurotomy. Since percutaneous mitral balloon valvulotomy is the treatment of choice in patients with mitral valve stenosis1, assessment of mitral valve suitability for percutaneous valvulotomy is of major importance in the management of mitral stenosis patients, particularly in patients with mild symptoms. Since 2-D echocardiography and Doppler echocardiography provide the necessary information to monitor most patients with mitral valve stenosis, there is generally no need for additional MR imaging studies. In patients with a discrepancy between symptoms and hemodynamics, an MR imaging study may add confirmatory data regarding the severity of the...

Risk factors for atherosclerosis

There are three classes of risk factor for atherosclerosis. Causal risk factors are those where evidence supports a direct cause-and-effect role. These risk factors include nicotine use, high blood pressure, elevated serum cholesterol or LDL, low HDL, and high plasma glucose.

Conventional Angiography

It is important to note diabetes, metformin treatment (http www.rcr.ac.uk pubtop.asp PublicationID 70), renal function, severe uncorrected hypertension, antiplatelet (aspirin) and anticoagulant (warfarin) treatment, recent cardiac and cerebral vascular events. These may constitute relative or absolute contraindications to a procedure, depending upon the condition of the patient. Factors such as the availability of recovery observation space and nursing staff within the radiology department will determine local practices.

Lipid Differences Between Omnivores And Vegetarian Or Vegans

The elderly vegetarian, particularly the elderly vegan, is in a protective life-style that minimizes ischemic damage, plaque formations, and lipid depositions involved in atherosclerotic disease, hypertension, stroke, or rheumatic heart disease. Plant dietary protein minimizes endogenous The PUFA are divided into omega-3, omega-6 and omega-9 groups. The omega-3 and omega-6 PUFA groups contain the two essential fatty acids linoleic acid, an omega-6 fatty acid, and alpha-linolenic acid, an omega-3 fatty acid (Figure 11.3).42 Underlying the necessity of meeting the alpha-linolenic acid requirement are the demonstrated effects of omega-3 fatty acids in suppressing carcinogenesis, allergic hyperactivity, thrombotic tendency, apoplexy, hypertension, hypertriglyceridemia, and aging in animals. The suppression of allergic hyperactivity is a suppression of the immune system, particularly marked with fish oils as the source of the omega-3 fatty acids, as a combination of alpha-linolenic,...

Answers and Explanations

Enlargement of and retrograde flow in gastric veins, in particular the left gastric veins, dilates the capillary bed in the wall of the esophagus in cases of portal hypertension. Blood flow would increase in and dilate tributaries of the azygous vein on the other side of the capillary bed, but flow in this vein is in the typical direction toward the superior vena cava. Paraumbilical vein engorgement contributes to a caput medusa. Splenic enlargement might present with splenomegaly, and backflow in to the superior mesenteric vein occurs but is asymptomatic.

The Focus And Purpose Of Therapy

I'm still not on blood pressure medication. I've had high blood pressure for five years now, because anyone I know who has gone on the medication, you never come off of it. Some people when they come off the pills, boom they've had a stroke or a heart attack because the body can't regulate itself without that medication any more.

Spina Bifida With Myelomeningocele

The oculomotor nerve CN III) innervates the levator palpebrae superioris the medial, superior, and inferior recti and the inferior oblique muscles. CN III palsy may be due to aneurysm, increased intracranial pressure, uncal herniation, diabetes meliitus, hypertension, or giant cell arteritis. Subarachnoid hemorrhage is most commonly due to a ruptured intracranial aneurysm, arteriovenous malformation, cerebrovascular accident, or trauma. The middle cerebral artery bifurcation is the most common location of intracranial aneurysms.

Management of Patients with Carotid Bifurcation Disease

A 72-year-old white male was referred for evaluation and management following the finding of an asymptomatic carotid bruit, picked up on routine physical examination by his primary-care physician. The patient was asymptomatic with respect to ocular or hemispheric ischaemic events. His risk factors included a 30-year history of smoking one pack of cigarettes a day, which he quit a year ago. He had hypertension that was controlled well by two drugs. He had no history of coronary artery disease, diabetes mellitus, or symptoms of peripheral vascular disease. On physical examination, his temporal pulses were equal. His carotid pulses were full and equal, but there was a loud bruit over the right carotid bifurcation. His femoral, popliteal, dorsalis paedis and posterior tibial pulses were normally palpable bilaterally.

Intracranial Small Vessel Disease

Occlusion of the penetrating end arteries (lenticulostriate, thalamoperforate) in the deep structures of the brain causes discrete wedge-shaped infarctions of brain tissue. These ischemic lesions, termed lacunar infarcts, are responsible for up to 25 of ischemic carotid territory strokes. Conditions predisposing toward lacunar infarction include hypertension and diabetes. There is still considerable debate as to whether embolization from a carotid stenosis can cause lacunar infarction.

Type 2 Diabetes Mellitus

Retrospective studies looking at diabetes prevalence over time have generally noted an increased prevalence with age in women with PCOS. Studies from Scandinavia have shown increased rates of type 2 diabetes and hypertension compared with controls (53). This study used a combination of ovarian morphology and clinical criteria to identify women with PCOS and found that 15 had developed diabetes, compared with 2.3 of the controls (53). A case-control study of PCOS in the United States has shown persistent

Cardiovascular Risk Factors

The metabolic profile noted in women with PCOS is similar to insulin resistance syndrome, a clustering within an individual of hyperinsulinemia, mild glucose intolerance, dyslipidemia, and hypertension (73). There is a prolific literature identifying obesity, dyslipidemia, glucose intolerance, diabetes, and occasionally hypertension as risk factors for cardiovascular disease in women with PCOS (74-79). However, there is actually little published evidence supporting a link between PCOS and cardiovascular events i.e., increased mortality from CVD, premature mortality from CVD, or an increased incidence of cardiovascular events (stroke and or myocardial infarction).

Pharmacological Management Estrogens

Because sympathetic-nerve stimulation of the alpha-adrenergic receptors located in the intrinsic sphincter or bladder neck region produces smooth muscle contractions, cases of mild stress incontinence have responded to the use of oral alpha-adrenergic agents (26). In the case of stress incontinence, the most commonly used agents are ephedrine, pseudoephedine, and phenylpropanolamine all are the active components of commonly used over-the-counter decongestants. The usual adult dosage of phenylpropanolamine is 25-100 mg in sustained-release form, given orally twice a day that of pseudoephedrine is 15-30 mg three times a day. Side effects are numerous and are associated with the drug's lack of bladder neck selectivity. Typical manifestations of the nonspecific action of this medication include an increase in blood pressure, stomach cramping, and central nervous system (CNS) symptoms of excitation and drowsiness. These drugs must be used with caution in patients with hypertension,...

Gases Respiratory Care

As the dose rises (2-10 mg kg min), -receptor activity predominates and the inotropic effect on the myocardium leads to increased cardiac output and blood pressure. Above 10 mg kg min, a-receptor stimulation causes peripheral vasoconstriction, shifting of blood from extremities to organs, decreased kidney function, and hypertension. At all doses, the diastolic blood pressure can be expected to rise since coronary perfusion is largely a result of the head of pressure at the coronary ostia, coronary blood flow should be increased. 68. The answer is c. (Charlson, Ann Surg 210 637-648, 1989.) The landmark study by Goldman in 1978 identified cardiac risk factors in noncar-diac surgical patients that included previous infarction (particularly infarction within 6 mo, but with increased risk continuing for life), functional impairment such as dyspnea on exertion, age over 70 years, mitral regurgitation, more than five premature ventricular contractions (PVCs) per minute, and a...

Lifestyle changes and nonpharmacological therapy

The primary treatment of hypertension definitely starts with lifestyle changes, especially in individuals with borderline hypertension. Diet and weight reduction, if needed, are the primary treatments. A low-fat, low-salt diet is important. Weight loss of 10-20 may obviate or reduce the need for pharmacological therapy. Patients who lose weight may be able to stop medication. A weight loss of 10 kg may reduced a woman's risk of hypertension by 26 . Alternatively, an increase in weight of 1 kg is associated with a 12 risk of developing hypertension.7 Reducing alcohol consumption is also important.

Captopril is a rationally designed, competitive inhibitor of peptidyl dipeptidase. It blocks the formation but not the response of angiotensin II. Captopril is useful in reducing the blood pressure of both renin-dependent and normal-renin essential hypertension The hypotensive action of clonidine is believed to be due primarily to stimulation of the a-adrenergic receptors in the CNS. A reduction in the discharge rate of preganglionic adrenergic nerves occurs in addition to bradycardia. The CNS actions of clonidine also lead to a reduction in the level of renin activity in the plasma. Los art an blocks angiotensin type I (ATI) receptors 200, The answer is c.

Pulmonary Vascular Disease

The PA view shows the cardiac silhouette to be slightly off center but not enlarged. The aortic knob is at the lower limits of normal. The pulmonary outflow tract is large and both the right and left pulmonary arteries are prominent. The peripheral vasculature shadows appear attenuated, especially in the right lung. There are no abnormal lung parenchymal shadows. The lateral view shows that the anterior clear space behind the sternum is occupied above a portion of the lower one-third of the cardiac shadow. The truncus of the right pulmonary artery seen in front of the trachea is very large and the left main pulmonary artery coursing over the left upper lobe bronchus is greater than 16 mm. These findings are consistent with pulmonary arterial hypertension.

Pharmacological therapy

Pharmacological therapy is initiated in individuals in whom lifestyle changes are not accomplished or are inadequate to control hypertension and in those individuals who have sustained blood pressure readings greater than 160 mmHg systolic and or 100 mmHg diastolic.9 In individuals with diabetes or who have evidence of end-stage target organ damage, treatment should be started if blood pressure is higher than 140 90 mmHg.3 Diuretics are effective antihypertensive medications, but they may worsen incontinence and glycemic and lipid control, and theymay cause hypokalemia. Angiotensin-converting enzyme inhibitors (ACEIs) are effective treatment and have many other effects, some of which are not understood. They protect renal function in diabetics, and one study found recently that ramipril decreased the risk of stroke, even in diabetic individuals who were not overtly hypertensive.12 However, up to 49 ofwomenon, ACEIs may develop a cough. The angiotensin II inhibitors are another good...

Molecular Biology of Kidney Cancer

Kidney cancer, more commonly known as renal cell carcinoma,is the sixth leading cause of cancer death in the United States 1 . It currently accounts for approximately 3 of all adult malignancies 1 .In 2001,32,000 cases of renal cell carcinoma in the United States were documented. Of these 32,000 cases, approximately 40 will die of the disease 1 . Renal cell carcinoma is more common in males than in females, with approximately a 2 1 ratio. It typically affects patients between the ages of 50 and 70 but may occur in younger individuals, especially those who suffer from familial syndromes 2-5 . The number one risk factor for the disease is cigarette smoking. Other risk factors include obesity and hypertension, which are thought to be particular risk factors for females who develop renal cell carcinoma 3-5 . Occupational exposures such as leather finishing products and asbestos have also been associated with the development of renal cell carcinoma 6,7 .Also an increased incidence has been...

General Discussion

An increase in pulmonary artery pressure is called pulmonary hypertension. The various mechanisms of this increase include (1) increase in left atrial pressure, as seen in mitral stenosis and left ventricular failure. This is further discussed in Chap. 15. (2) Increase in pulmonary blood flow, as occurs in congenital heart disease and left-to-right septal defects. Initially this causes no structural distortion in the vascular bed, since capillary distensi-bility and recruitment compensates for this increased pressure. Later, however, sustained increased pressure causes changes in small vessels with development of right-to-left shunt. (3) Increased pulmonary vascular resistance the most common cause of cor pulmonale. This may be due to alveolar hypoxia, as seen in COPD, and is called secondary pulmonary hypertension. It is related to release of mediators such as serotonin and cat-echolamines. In pulmonary thromboembolic disease, the vessels are obstructed by thrombi or circulating...

Clinical Features of Nonatherosclerotic Disease

One of the characteristic features of the non-atherosclerotic pathologies listed earlier is the potential for thrombosis stenosis and aneurysm formation. Accordingly, each condition can cause ischemic stroke TIA, but most are relatively rare. The onset of stroke TIA in a patient exhibiting other atypical features should raise the possibility of a nonatheromatous pathology. Sudden onset of temporal headache or neck pain associated with a neurological or visual deficit is suggestive of carotid dissection. The initial neurological symptoms are thought to be due to acute expansion of the dissection resulting in compression of cranial nerves IX, X, XI, or XII, followed by cerebral ischemia. Horner syndrome can also occur, which is believed to be due to disruption of periadventi-tial sympathetic fibers adjacent to the carotid artery. Systemic illness, malaise, weight loss, and myalgia suggest an underlying arteritis (Takayasu, giant cell, SLE, polyarteritis). Jaw claudication is an...

Investigation of Ischemic Stroke

All patients should undergo simple baseline investigations (full blood count, urea electrolytes, glucose, lipids, chest x-ray, electrocardiogram). This not only enables diagnosis of unexpected coexistent pathologies (sickle cell disease, thrombocytosis, etc.), but also enables important risk factors to be corrected (hypertension, diabetes, ischemic heart disease, etc.). There is no need for more complex investigations to be performed routinely (autoantibod-ies, echocardiograms, thrombophilia screens). These should only be undertaken if the history or initial investigations suggest it is appropriate.

Obesity and impaired glucose tolerance (IGT) are associated with a greater health risk for a number of conditions, including insulin resistance, diabetes mellitus, hypertension, dyslipidemia, coagulation abnormalities, inflammatory markers, and coronary heart disease. Lifestyle changes can delay or prevent the development of type 2 diabetes in patients with obesity and IGT. The risks improve with weight loss and increased physical activity. A decrease of 7 to 10 or more from baseline weight can have a significant effect. This has now been documented in a number of randomized controlled studies. This essay is directed on how the Diabetes Prevention Program approach to lifestyle change can be translated in a meaningful way to routine clinical care practice settings.

Increase in Prevalence of Obesity

The National Health and Nutrition Examination Survey (NHANES) III, which was conducted from 1988 to 1994, showed that 59.4 of men and 50.7 of women in the United States are overweight or obese. In the period between the second NHANES survey and the third, the prevalence of obesity rose from 14.5 to 22.5 (7). More recent data has put the figure at 30.5 for obesity and 64.5 for overweight (8). Obesity is also increasing rapidly in other parts of the world (8). Global obesity increased from an estimated 200 million adults in 1995 to more than 300 million in 2000 (9). Childhood obesity has also increased. During the past 30 yr, childhood obesity in the United States has more than doubled (10). As obesity increases, it leads to an increased disease burden (11,12), increased mortality (13), and a shortened life span (14). It brings with it not only an increased incidence of type 2 diabetes, but also of dyslipidemia, hypertension, and cardiovascular disease.

Abnormal Glucose Metabolism and Type 2 Diabetes

Fat distribution is also very important in diabetes risk (22-25). Central or upper body fat deposition is independently associated with insulin resistance (23), diabetes (24,25), and cardiovascular disease (26). Intra-abdominal or visceral obesity is strongly associated with insulin resistance, as well as with dyslipidemia, hypertension, and glucose intolerance (27-30). In Japanese American men intra-abdominal fat deposition was closely correlated with type 2 diabetes, whereas subcutaneous fat deposits in the abdomen, thorax, or thigh were not statistically significant predictors (31).

Vertebrobasilar Ischemia Embolic Mechanism

A 51-year-old male experienced over a period of 6 months a major stroke and several transient ischemic attacks (TIAs) of vertebrobasilar distribution. The original episode consisted of loss of balance, loss of coordination, and loss of the left visual field while driving a bus, which resulted in a road accident. Since then, he had experienced four additional episodes of aphasia and paraparesis lasting for 4-5 h. A diagnosis of vertebral artery dissection was made at the local hospital and he was placed on Coumadin. Concomitant diagnoses were hypertension, non-insulin-dependent diabetes, and hypercholesterolemia. In spite of adequate international normalized ratio (INR) levels, his symptoms continued and he was referred to us.

Treatment of Atrial Fibrillation

Mately 5 of the population aged > 65 years have NVAF, incurring a 3 to 5 annual risk of stroke. Treatment with warfarin reduces the risk of stroke by 68 but decisions regarding the role of anticoagulation must take into account the potential hemorrhagic risks. The annual risk of significant bleeding in anticoagulated patients is 1.3 , including a 0.3 incidence of intracranial hemorrhage. Patients at increased risk of significant hemorrhage include those with the following findings a previous history of bleeding, age > 75 years, an international normalized ratio (INR) > 3.0, fluctuating INRs, and uncontrolled hypertension. Although each case must be considered individually, it is generally recommended that patients considered high risk for embolic stroke be warfarinized with a target INR of < 3.0. High-risk patients (6 annual stroke risk) include (1) those of any age with a past history of TIA or stroke, rheumatic heart disease, ischemic heart disease, and evidence of impaired...

Treatment of Hyperlipidemia

In the U.S., statin therapy is advised in all patients with TIA stroke and coronary heart disease. In patients with no coronary heart disease and fewer than two vascular risk factors (selected from men aged > 45 years, women aged > 55 years, family history of heart disease, smoking, hypertension, diabetes, high-density lipoprotein (HDL) cholesterol < 35mg dL), the advice is to try dietary modification for 6 months and to introduce statin therapy only if the low-density lipoprotein (LDL) cholesterol is > 190mg dL with a target of < 160mg dL. The TIA stroke patients with no history of coronary heart disease (but having more than two risk factors) should undergo dietary modification for 6 months followed by statin therapy if the LDL cholesterol is > 160mg dL with a target of reducing it to < 130mg dL.

Premorbid Level of Functioning

Population studies in which the criteria for defining the population are expressed in detail. It has to be concluded, however, that these details are often missing. It is not always clear whether individuals with disorders affecting brain function, or with latent disease (e.g. incident dementia), or carrying risk factors for brain dysfunction (e.g. hypertension, hypotension, diabetes, heart problems, endocrinological disturbance, psychiatric syndromes, etc.) are excluded or not. Of course, sensory and motor difficulties also have to be considered. With few exclusions made, the population will cover a large proportion of all individuals, which will result in relatively low values of mean performance and high values of distribution spread. On the other hand, with many exclusions made, the population will cover a small proportion of all individuals, which will result in relatively high values of mean performance and low values of distribution spread. Thus, the concept of normality,...

Acyanotic Heart Disease

Small defects close spontaneously in 30-50 of cases by 2 years of age and require no therapy. Antibiotic prophylaxis for endocarditis is required. Medical management includes controlling heart failure, promoting normal growth, and preventing pulmonary vascular disease. Surgical closure is recommended for failure of medical management, or large defects with pulmonary hypertension that has not yet become severe. Patients with small VSDs and those having undergone surgical repair without residua have an excellent long-term prognosis. Complications. Large defects can result in heart failure and failure to thrive. All patients with unrepaired VSD are at risk for endocarditis. Pulmonary hypertension is another complication. Treatment. Surgery is performed during infancy because of the high risk of early development of pulmonary hypertension. The defects are patched, and the cleft mitral valve is repaired. Presentation. A coarctation may be missed in a newborn while the ductus is...

Neurological Manifestations

Neurological manifestations are present in 8-31 of all patients and mostly begin 4-6 years after the first manifestation of BD. In neuro-BD, parenchymal involvement is distinguished from non-parenchymal (vascular) involvement, where the parenchymal lesion, when it occurs, is secondary to another pathological process, such as large arterial or venous occlusion, haemorrhage, etc., and thus corresponds to a major vascular territory. Intracranial hypertension with or without dural sinus thrombosis is the most common manifestation of vascular neuro-BD and comprises 11-35 of all neuro-Beh et's patients. In parenchymal involvement, which is more common and is seen in 82 of all cases of neuro-Beh et, the pathological process occurs primarily within the nervous parenchyma, with a tendency to produce focal lesions clustering in the brainstem, basal ganglia, diencephalic structures, internal capsule, etc., and is also disseminated throughout the CNS as a low-grade inflammation 4,

Vascular Manifestations

Vascular manifestations occur in 28 and consist of thromboses and arterial aneurysms. Symptoms correlate with the localization and mostly occur 3-4 years after the first manifestation of BD.Venous thrombosis is more common than arterial complications. Most commonly occlusions of the superior or inferior vena cava, femoral veins, cerebral veins, veins of the upper extremities and liver veins (Budd-Chiari syndrome) occur. Rarely, also thrombosis of the renal veins, the portal vein with consecutive portal hypertension and intracardiac thrombus are seen 54, 150 . Pulmonary embolism is diagnosed in 10-15 of cases. There is an accumulation of thromboembolism in patients with additional coagulation defects such as prothrombin mutation, factor V Leiden mutation, protein C or protein S deficiency or hyperhomocys-teinaemia 35, 87,143 . However, thromboses in BD are due to vascular inflammation and the resulting endothelial dysfunction. The frequency of arterial complications is estimated at 7-

Retinoic Acid and the Heart

The requirement of RA during early cardiovascular morphogenesis has been studied in targeted gene deletion of retinoic acid receptors and in the vitamin A-deficient avian embryo. The teratogenic effects of high doses of RA on cardiovascular morphogenesis have also been demonstrated in different animal models. Specific cardiovascular targets of retinoid action include effects on the specification of cardiovascular tissues during early development, anteroposterior patterning of the early heart, left right decisions and cardiac situs, endocardial cushion formation, and in particular, the neural crest. In the postdevelopment period, RA has antigrowth activity in fully differentiated neonatal cardiomyocytes and cardiac fibroblasts. Recent studies have shown that RA has an important role in the cardiac remodeling process in rats with hypertension and following myocardial infarction. This chapter will focus on the role of RA in regulating cardiomyocyte growth and differentiation during...

Thoracoscopic Sympathectomy

A 22-year-old female undergraduate student who had had bilateral palmar hyperhydrosis since the fifth grade presented with hyperhydrosis that was refractory to noninvasive treatment. Her sweating was severe, to the point that it dripped and was thus incapacitating. Her symptoms become more severe primarily when she was anxious or upset, but they also increased with physical activity or elevated temperatures. She was unable to shake or hold hands in social settings. She had difficulty taking exams because the sweat made the paper wet. She was currently looking for a job and felt socially inhibited when being interviewed. Conservative therapy had failed, trying Drysol, Robinul, Drionic and roll-ons. Her hyperhydrosis had also proven refractory to hypnotherapy, biofeedback and iontophoresis. She denied any axillary hyperhydrosis. Her past medical history was negative for any major illnesses, and she denied any thyroid conditions, hypertension or diabetes. She had had no previous lung...

Achievement of optimum health status

This is perhaps one of the most challenging aspects of pre-assessing vascular patients. It is, first of all, necessary to assess the risk factors a high percentage of these patients are, or have been, heavy smokers, diabetic, suffer from hypertension, raised cholesterol, ischaemic heart disease (IHD) and lead a sedentary lifestyle. Thus achieving optimum health status can be quite difficult. It is also important to ensure that patients are taking their prescribed medications regularly (in particular antihypertensives, statins and aspirin) and understand the need for these medications.

Additional risk factors for type 2 diabetes include prior gestational (pregnancy-related) diabetes or delivery of a baby weighing over 4.1 kg, hypertension, dyslipidemia, family history of type 2 diabetes, and certain racial and ethnic groups (Table 15.1).

The role of retinoids in promoting the ventricular phenotype in the embryonic heart suggests that retinoids may also be important in maintaining normal ventricular phenotype in the postnatal state. We and others have demonstrated that RA inhibits mechanical stretch and G-protein-coupled receptor (GPCR)-mediated hypertrophy in neonatal cardiomyocytes (Palm-Leis et al., 2004 Wang et al., 2002 Wu et al., 1996 Zhou et al., 1995). It has also been shown that RA inhibits left ventricular fibrosis and has a role in ventricular remodeling during the development of hypertension in spontaneously hypertensive rats (SHR) and in the myocardial infarction rat model (de Paiva et al., 2003 Lu et al., 2003 Paiva et al., 2005). RA signaling could potentially serve as an alternative target in the prevention and treatment of pathological hypertrophy and heart failure.

Neurological Deficit After 24 Hours

Stroke due to hyperperfusion syndrome is another poorly understood entity, and there is considerable controversy as to whether it would be better renamed the reperfusion syndrome. More recently, there has been renewed debate as to how much the condition is associated with high flow as opposed to hypertensive encephalopathy or dysautoregulation. Patients at risk of hyperperfusion-related stroke tend to have a history of severe bilateral disease and treated hypertension. Stroke is often preceded by seizure and severe hypertension. The mainstay of management is control of seizures and careful reduction of blood pressure. Early CT scans often show changes consistent with an evolving ischemic infarction, but in fact this is often white matter edema. Paradoxically, a lot of the white matter edema is present in the verte-brobasilar territory.

Nuts Seeds And Oils

The increased life expectancy and low rates of chronic diseases such as heart disease, high blood pressure, diabetes, and cancer among the southern Europeans, may be, in part, due to their physically active, simple lifestyle and unique Mediterranean diet, which is especially rich in a variety of phytochemicals such as those found in olive oil, garlic and other herbs, beans, fresh fruit and vegetables.145,146

Antihypertrophic Effects Of Ra In Neonatal Cardiomyocytes

Cardiac hypertrophy occurs as an adaptive response to many forms of cardiac disease, including high blood pressure (hypertension), myocardial infarction, cardiac arrhythmias, genetic defects in cardiac contractile proteins, and endocrine disorders. Cardiac hypertrophy is characterized by an increase in myocyte cell size (in the absence of cell division) and by a number of qualitative and quantitative changes in gene expression. Many pathological stimuli induce the heart to undergo adaptive hypertrophic growth. Although the initial hypertrophic response may be beneficial, sustained hypertrophy often results in a transition to heart failure, which is a leading cause of mortality and morbidity worldwide, and is characterized by a progressive deterioration in cardiac function. Cardiac hypertrophy is generally associated with the expression of atrial natriuretic peptide (ANP) that is restricted to the atria shortly after birth, and is reexpressed in the ventricles following hemodynamic...

Blood Pressure Health

Blood Pressure Health

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
