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.

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...

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...

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...

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.

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


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).

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...

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.

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...

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.

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.

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.

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...

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.

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...

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 90 ) carotid stenoses may be predisposed to ICH, particularly with concurrent hypertension and...

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 (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...

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.

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).

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...

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,...

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...

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.

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...

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.

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 190mg dL with a target of 160mg dL with a target of reducing it to

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...

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...

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.

Effects Of Ra Signaling In Cardiac Remodeling

Left ventricular (LV) remodeling has a major role in the progression to heart failure. This process is associated with alterations in ventricular mass, chamber size, shape, and function that result from myocardial injury, pressure, or volume overload. At the cellular level, LV remodeling is characterized by myocyte hypertrophy, fibroblast hyperplasia accompanied by an increase in collagen deposition within the interstitial matrix (fibrosis), and cell death. Although remodeling is initially an adaptive response to maintain normal cardiac function, it often becomes maladaptive and leads to progressive decompensation. Elucidating the mechanisms responsible for preventing and or reversing the process of LV remodeling may lead to identifying novel therapeutic targets for the treatment of heart failure.

The prevalence of overweight and obesity is reaching epidemic proportions nationally and worldwide.75,76 In the U.S., 55 of adults aged 20 years and older are either overweight or obese. Overweight is defined as having a body mass index (BMI) of 25.0 to 29.9 kg m2 and obesity as BMI equal to or greater than 30 kg m2. Similar trends are observed in children and adolescents with a doubling of the number of obese children from 20 years ago.75 Obesity is a major risk factor for coronary heart disease, hypertension, type 2 diabetes, stroke, gallbladder disease, osteoar-thritis, respiratory problems, and some cancers. In addition to the enormous health consequences that result in increased health care costs, there are significant social and psychological burdens for obese individuals and their families.77 C. Hypertension Guidelines High blood pressure is one of the most common health problems in industrialized countries. Among U.S. adults, about one fourth suffer from hypertension. Certain...

Cerebral Arteriosclerotic Vascular Disease

Triglycerides have also been shown to inhibit the progression of early carotid arteriosclerotic vascular disease, and the Losartan Intervention For Endpoint Reduction in Hypertension study (45) has demonstrated that losartan (Cozaar) can be effective in reducing stroke in hypertensive diabetic patients.

Carbon Monoxide Poisoning

PE VS hypertension (BP 180 95) tachycardia (HR 160). PE restless, malnourished, and disoriented. Monitor vital signs and ECG for several hours. There are no specific antidotes for cocaine use. Propranolol may be used with a vasodilator for treatment of hypertension and tachyarrhythmias. Dialysis and hemoperfusion are not effect i ve. catecholamine reuptake mechanisms hence, its use results in a state of generalized sympathetic stimulation, with typical symptoms including euphoria, anxiety, psychosis, and hyperactivity. Severe hypertension, ventricular tachycardia, or fibrillation may also occur. Angina pectoris iti a young, healthy person is suggestive of cocaine use. Myocardial infarction secondary to coronary vasospasm and thrombosis have been described as well.

Risk Factors for Abdominal Aortic Aneurysm

Factors associated with an increased risk of aneurysmal development in the infrarenal aorta include increasing age, male sex, ethnic origin, family history, smoking, hypercholesterolemia, hypertension, and prior vascular disease. Studies suggest that of these, male sex and smoking are the most important, increasing the chances of AAA development by 4.5 and 5.5 times, respectively. A positive family history (first-degree relative affected) alone doubles the risk of AAA presentation and is more likely if the affected relative is a female. Interestingly,

Computed Tomography Scanning

The advent of spiral CT scanning in some centers has led to increased speed of assessment (a single breath hold) with the ability to reconstruct CT images in a three-dimensional manner, resulting in a more user-friendly and informative imaging. The use of CT scanning must be judicious in patients with a prior history of contrast reaction, high blood pressure, and preexisting renal impairment. As with ultrasound, CT scanning cannot detect visceral artery involvement or the presence of renal artery stenosis, and this must be remembered in assessment of the generated images.

Cardiovascular Morbidity

A number of studies have suggested a higher than expected incidence of cardiovascular disease (CVD) in patients receiving chemotherapy for metastatic disease. The largest of these studies has suggested that after a median of 10 years' follow-up, there may be a twofold or greater risk of developing CVD in such patients when compared to (stage I) matched patients followed by surveillance alone the absolute risk is 6.7 , and the age-adjusted relative risk is 2.59 (95 confidence interval CI , 1.1 to 5.8) 53 . A variety of potential mechanisms could ac-count for an increased risk of CVD following chemotherapy, including vascular endothelial damage, renal impairment, hypertension, hyperlipi-demia, and an increase in body mass index. Although no clear relationship was established for any of these risk factors in this study, other studies have demonstrated a relationship between chemotherapy and an increased incidence of classical CVD risk factors such as plasma lipid profiles and raised...

False Aneurysms and Arterio Venous Fistulas

Indecisiveness about the order of sequence can be overcome if artery and (if necessary in order to avoid venous hypertension and compartment syndrome) vein are bridged by intraluminal shunts (Fig. 7.7.14) right from the beginning. If venous return is severely compromised this can cause venous hypertension and trigger the development of compartment syndrome.

Depression in the Elderly Areas Open to Research

Vascular depression is an interesting and potentially important concept. It is suggested that areas of infarction, particularly those in the left frontal lobe, or deep white matter hyperintensities identified by magnetic resonance imaging (MRI) scan (probably indicative of microvascular pathology), predispose to affective disturbance. Work from our own group has also suggested the importance of deep white matter lesions on MRI as an association of depression in Alzheimer's disease 5 , and work in preparation indicates that microvascular lesions and diffuse white matter disease, identified at neuropathological examination, are significantly correlated with depression in vascular and mixed dementias. A very consistent picture is hence emerging, drawing evidence from a number of different disciplines, substantiating the concept of vascular depression in the elderly. Simpson et al 6 have suggested that these patients are more likely to be treatment resistant and to progress into a chronic...

Hormones Produced By The Cortex Of The Adrenal Glands

Hypersecretion of Mineralocorticoids. Hypersecretion of mineralocorticoids (aldosterone) can lead to increased sodium reabsorption. This can also lead to decreased reabsorption of potassium into the blood. Ultimately, hypersecretion of aldosterone can result in an increased volume of extracellular fluid, which leads to increased volume of blood. This can increase cardiac output, ultimately resulting in hypertension.

Medications to Increase Outlet Resistance

Alpha adrenergic agonists have been used to increase bladder outlet resistance. Their use is based on studies that show an abundance of alpha-adrenergic receptors at the bladder neck and proximal urethra (103,104). Ephedrine is a treatment used for stress urinary incontinence (SUI). It enhances the release of norepinephrine from sympathetic neurons and stimulates directly the alpha and beta-adrenergic receptors (105). The usual dose is 25-50 mg QID and tachyphylaxis has been reported. Pseudophedrine, a steriosomer of ephedrine, can also be used at a dose of 30-60 mg QID. The use of these drugs for severe SUI is limited and may only be of benefit for minimal wetting (106,107). Phenylpropanoamine (PPA) has the same pharmacologic properties as ephedrine and has been used for SUI at a dosage of 50 mg BID. The side effects of these medications include anxiety, headaches, tremor, weakness, palpitations, cardiac arrhythmias, hypertension, and respiratory difficulties. Thus, these medications...

Medications Monotherapy

Different classes of medications are beneficial in the management of hypertension in patients with diabetes, including ACE inhibitors and angiotensin-receptor blockers (ARBs). The ALLHAT trial showed benefits of chlorthalidone therapy in the hypertensive and diabetic subset (8). For individuals who are 55 years of age or older, either with or without hypertension, ramipril at doses titrated up to 10 mg is the agent of choice in view of the outstanding data from the Heart Outcomes Prevention Evaluation (HOPE) trial (9). Carvedilol has improved left ventricular ejection fractions and decreased mortality rates in both diabetic and nondiabetic patients with congestive heart failure. In a doubleblind, randomized trial, the effects of the ACE inhibitor, perindopril (Aceon) on blood pressure and endothelial function were compared with carvedilol in 26 diabetic patients with hypertension. Both perindopril and carvedilol significantly reduced mean blood pressure and increased leg blood flow to...

When Should We Use Which Diagnostic Tools

This also holds true for white matter lesions on computed tomography (CT) and magnetic resonance imaging (MRI), which have been shown to increase in amount and frequency with age and vascular risk factors, especially arterial hypertension and smoking. Their presence does not automatically mean a vascular dementia or a mixed dementia 6 . With proton magnetic resonance spectroscopy it became possible to non-invasively monitor neuronal loss by a reduced concentration of N-acetyl-aspartate (NAA) and gliosis by an increase of myo-inositol.

Answers and Case Discussion

This middle-aged white female had significant risk factors in the form of obesity, hypertension, and diabetes, even though no family members were known to have had a myocardial infarction. Although the description of her pain, its radiation, and the way she related the pain to a fatty meal could suggest gallbladder disease, it is also entirely compatible with AMI. Nausea, vomiting, diaphoresis, and a mild sensation of shortness of breath could be common to both. Important aspects of the physical examination included wet skin and an S4 gallop. Both findings are compatible with AMI, but wet skin can also be present in patients who are vomiting and in pain with acute cholecystitis, and an S4 may be seen with hypertension alone. Nevertheless, the findings increase the index of suspicion for, and lend support to, a potential diagnosis of AMI.

Direct and Indirect Costs

Indirect costs include the impact on productivity, days lost from work, forgone leisure time, and increased mortality. Compared with other chronic conditions, the costs associated with depression are more likely to be productivity losses caused by absenteeism and suboptimal performance in the workplace 3, 30, 37, 42 . Depressed workers can experience short- and long-term absences from work leading to reduced earnings capacity over time 43 . One study has found that the magnitude of short-term disability appears to be greater than other chronic conditions such as diabetes, back pain, and high blood pressure 44 . The costs of depression are therefore more hidden and insidious than those associated with other chronic illnesses.

Mitral Stenosis Never Too Late To Operate

Selection for the best interventional procedure is based on valve morphology and comorbididty. As discussed elsewhere, valve morphology can be scored 24 in a 16 point scale and when this score, describing leaflet mobility and thickening as well as the status of the subvalvular apparatus and calcification present, exceeds 8, balloon- valvuloplasty is associated with a suboptimal result and complications 25. Of course it is hazardous to apply a rigid breakpoint for clinical decision making in patients with intermediate scores echocardiographer, interventionalist and surgeon should review valve morphology together to decide for the most appropriate therapy. This holds true even more in patients where the surgical risk is high, patients with pulmonary hypertension. In these patients the mortality rate of surgery is high, in one study of 42 patients with pulmonary systolic pressures of 60 mmHg and higher this rate was 11.6 , as is the complication rate, in the same study 16 26. In these...

Anatomical Tests Duplex Ultrasound

Although this is an excellent screening test to detect the presence of renal artery stenosis, duplex examination is unable to accurately predict the clinical response of either the hypertension or renal insufficiency following correction of the RAS. It is also unable to accurately identify all accessory branches of the renal artery and their contribution to the clinical picture. This is, however, an appropriate nonin-vasive screening test to evaluate for RAS and is useful for following the patient with serial examinations after intervention.

Medical Management of Symptomatic Renal Artery Stenosis

The medical management of symptomatic RAS is accomplished using a variety of antihyper-tensive medications in an attempt to control the hypertension. Control of the hypertension in itself is critical, as uncontrolled hypertension is a major risk factor for myocardial infarction, cerebrovascular accident, and chronic renal insufficiency. Thus, the goals of medical management of symptomatic RAS are to reduce the blood pressure, to control cardiovascular risk factors, and ultimately to prevent end-organ damage from sustained hypertension. Hunt and Strong (1973) orchestrated a comparative analysis examining drug therapy compared to operative therapy to treat symptomatic RAS 114 patients were in the medical treatment arm and 100 patients were in the surgical treatment arm. The follow-up was over the course of 7 to 14 years. Overall, 84 of patients were alive in the surgical group compared to 66 alive in the group treated medically. Of those alive in the surgical group, 93 were cured or...

Blood Pressure Control

Interestingly, blockage of the angiotensin II type I receptor has been shown to improve endothelial function and diminish endothelial adhesiveness. Angiotensin II promotes sodium retention, vasoconstriction, slows progression of glomerular injury at the renal level, and induces cardiac and vascular myocyte hypertrophy, fibromuscular proliferation, and endothelial cell apoptosis (22). With this in mind, the concept of combined therapy with angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) to lower blood pressure, reduce proteinuria, and reduce overall risk (including congestive heart failure CHF ) has received considerable attention. Therefore, there has been a trend in clinical practice toward combining therapy with both agents. Based on their different mechanisms of action, ACE inhibitors and ARBs can have synergistic effects. ACE inhibitors block the conversion of angiotensin I to angiotensin II and also inhibit the breakdown of vasodilatory...

Critical Growth Periods

There may be several critical periods during which adipose tissue development may be more of a factor in the long-term development of obesity (21). Three such periods are the prenatal period (22), the period of adiposity rebound (23), and puberty (24). Both high and low birthweights have been shown to correlate positively with rates of obesity later in life. Infants of diabetic mothers and other very large infants, as well as infants whose mothers were energy-deprived during the first two trimesters, are at significantly increased risk for hypertension, diabetes, and obesity later in life.

Regurgitant Valve Pathology

Rheumatic mitral regurgitation is becoming rare in the last ten years, and is often complicated by an associated mitral stenosis. Other -rare- causes are lupus erythematosus, the antiphospholipid antibody syndrome and the after-effects of infective endocarditis. Acute mitral regurgitation due to ruptured chordae tendinae or valve perforation due to bacterial endocarditis is very rare during pregnancy, but always very severe.2 Women with mitral regurgitation in the childbearing age, usually still have a well-functioning adaptive cardiac mechanism to volume overload. Their disease has rarely progressed to severe states. However, in few cases, the constant unloading of the left ventricle into the left atrium has already resulted in a reactive pulmonary hypertension, left ventricular enlargement and right-sided heart failure. The presence of cardiomegaly, atrial fibrillation and right-sided decompensation is associated with elevated maternal risks. In these patients, it might be...

Try to get enough rest and sleep

High blood pressure (p. 125) and hardening of the arteries (arteriosclerosis), which are the main causes of heart disease and stroke, can usually be prevented or reduced by doing the things recommended above. The lowering of high blood pressure is important in the prevention of heart disease and stroke. Persons who have high blood pressure should have it checked from time to time and take measures to lower it. For those who are not successful in lowering their blood pressure by eating less (if they are overweight), giving up smoking, getting more exercise, and learning to relax, taking medicines to lower blood pressure (antihypertensives) may help.

Understanding the Economic Implications of Depression

Depressive disorders produce a heavy economic burden at the personal, family and societal levels. This burden can be reduced considerably by cost-effective interventions. While suffering from depression, the individual's working capacity is considerably impaired, and depression causes more disability than any other mental disorder. One international multicentre study showed that mental disorders (depression being near the top of the list) were more strongly correlated with disability than common physical illnesses such as diabetes mellitus and hypertension in primary care settings 1 . It is thus quite clear that depressive illness is a high health management priority. However, all health care interventions have major cost implications.

Pharmacological Treatment

A limited number of medications are currently available in the pediatric age group for use as adjuncts to behavioral management. Sibutramine (Meridia) is currently available for the treatment of adolescents 16 yr of age or older. Sibutramine is a norepinephrine and serotonin reuptake inhibiter and has side effects that include hypertension, tachycardia, dry mouth, headache, constipation, and insomnia. When used in conjunction with a group-based behavioral therapy, sibutramine plus behavioral therapy led to a more rapid decline in BMI than behavioral therapy alone (91). Sibutramine should not be administered in conjunction with monoamine oxidase inhibitors or other serotonin reuptake inhibitors. Another pharmaceutical alternative is orlistat (Xenical). Orlistat binds gut lipase and prevents hydrolysis of dietary fats into free fatty acids and monoacylglycerols. Its side effects, which often lead to discontinuation of the medication, include flatulence, diarrhea, steatorrrhea, and...

National Vascular Database And Vpossum

POSSUM stands for Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity. It was developed by Copeland and co-workers and has since been applied to a number of surgical procedures. POSSUM aims to adjust the risk of a surgical procedure based on the patient's physiological condition and therefore allow a more accurate comparison of a team's performance. Twelve physiological (including age, systolic blood pressure and heart rate) and six operative (including operative blood loss and peritoneal contamination) parameters are measured. Each of these 18 factors are weighted and used in a formula to calculate the predicted mortality and morbidity. Prytherch and colleagues modified the original POSSUM formula for use in elective vascular surgery. When applied to Vascular surgery it carries the V-prefix. With the increasing emphasis on informed consent such a scoring system is particularly useful in giving individual patient's information regarding the...

Pros and Cons of Regional Anesthesia and General Anesthesia for Carotid Endarterectomy

The advantages of regional anesthesia are more often seen in a different patient population than with that of general anesthesia. Published selective shunt rates in regional anesthesia are in the range of 15 , which is a lower rate of shunting than techniques that involve monitoring. Regional anesthesia has been shown to invoke less postoperative hypertension and hypotension and reduced postoperative intensive care unit and hospital stay.

The answers are 405-d, 406-a, 407-a, 408-e. (Wallace, 14 e, p 895. USPS Task Force, 2 e, p xli.) Primary prevention prevents the occurrence of the condition disease. Thus, using condoms prevents the acquisition of an STD, and pasteurizing milk prevents brucellosis and other diseases. The treatment of syphilis during pregnancy prevents the infection of the fetus and congenital syphilis, and thus is a primary prevention for the newborn. Treating the mother also prevents the complications of untreated syphilis, such as neurosyphilis, and thus is a measure of tertiary prevention for the mother. Secondary prevention measures are used to detect and treat disease before it becomes clinically manifest. Screening for hypertension in asymptomatic persons is both a secondary measure and a primary measure as it also prevents the occurrence of strokes.

Endovascular Repair of Renal Artery Stenosis

Weibull and associates (1993) prospectively and randomly assigned 58 patients with symptomatic RAS to either renal angioplasty or surgical renal revascularization. Percutaneous transluminal angioplasty (PTA) was initially technically successful 83 of the time, whereas surgical management was successful 97 of the time. The primary patency rate after 2 years was 75 in the PTA group compared to 96 in the surgical group. Secondary patency was 90 versus 97 , respectively, in the PTA and surgical patients. Hypertension was improved in 90 after PTA and 86 following open surgical renal revascularization, and improvement in renal function was seen in 83 and 72 , respectively. The authors concluded that PTA is a reasonable option when compared to surgical revascular-ization. Indeed, the primary patency was lower in the endovascular group, but the secondary patency was comparable. Patients treated with angioplasty of RAS clearly require close surveillance and often subsequent procedures to...

Drugs on the Near and Distant Horizons

The 1-yr phase III trial with a 1-yr open-label extension randomized 501 subjects to placebo and 1467 subjects to axokine at a dose of 1 g kg d (90). Subjects had a BMI between 30 and 55, if their obesity was uncomplicated, or between 27 and 55, if their obesity was complicated by hypertension or dyslipidemia. At the end of 1 yr, the axokine group lost 3.6 kg, compared with 2.0 kg in the placebo group (p 0.001), a difference that does not meet the FDA efficacy criteria for approval. The most common adverse events were mild and included injection site reactions, nausea, and cough. The most concerning finding, however, was that two-thirds of those receiving axokine developed antibodies after 3 mo that limited further weight loss, and there was no way to prospec-tively predict those who would develop the antibodies. Development of axokine has been terminated.

Followup Prevention Of Complications

Phenomena is more common in patients with cervical injuries, and common triggers include bowel and bladder distention. Symptoms may involve piloerection, diaphoresis, pounding headache, flushing above the level of the injury, and may be associated with sudden and severe hypertension accompanied by reflex bradycardia. Although bradycardia is most common, tachycardia and arrythmias may be present. Hypertension may be of varying severity from causing a mild headache to a seizure or life-threatening cerebral hemorrhage. Therefore, it is necessary to monitor the blood pressure in these patients with any visceral stimulation. Immediate management when dysreflexia occurs is to discontinue the procedure. A life-threatening episode can be terminated by Procardia 10 mg sublingual (82), which has also been shown to be capable of preventing this syndrome when given orally 30 min prior to the procedure (82). The use of general or spinal anesthesia may be used in refractory cases. Prophylaxis...

Protein Differences Between Omnivores And Vegetarians Or Vegans

A varied diet based on plant proteins is adequate, yielding growth and body maintenance results equivalent to a diet based on meat protein.39 The lower incidence of obesity, constipation, lung cancer, hypertension, coronary artery disease, type 2 diabetes, gallstones, reduced risk of breast cancer, diverticular disease, colon cancer, calcium kidney stones, and osteoporosis appear to be obvious advantages particularly of the well balanced vegan diet for the elderly.3,39,40 Key et al.,40 (Table 11.1) show the protective effect of daily fresh fruit intake in ischemic heart disease, cerebrovascular disease, and lung cancer, and daily raw salad protection for ischemic heart disease. They also presented a higher incidence of breast cancer in the vegetarian women, but the confidence interval was broad. The smokers in their study population demonstrated a higher rate of ischemic heart disease, cerebrovascular disease, and, of course, lung cancer, to emphasize the disease problems associated...

Expiratory phase becomes prolonged and the patient develops tachypnea, tachycardia, and mild systolic hypertension. Accessory muscles of respiration (sternocleidomastoid and intercostals) may be used to improve breathing. If the asthma attack is severe, the patient will develop a pulsus paradoxus (an inspiratory drop in systolic blood pressure of more than 10 mm Hg). Patients with epiglottitis present with fever, drooling, and dysphagia lung examination will be normal. Children with croup or laryngo-tracheobronchitis present with labored breathing and stridor, and use accessory muscles to assist breathing.

Aortofemoral Graft Infection

A 66-year-old man, an ex-smoker with hypertension and hypercholesterolemia, had undergone a Dacron bifurcated aortic graft and bilateral ureteric stents for an inflammatory aortic aneurysm with ureteric obstruction at another hospital 4 years previously. The left limb of the graft had been anastomosed to the common femoral artery and the right limb to the common iliac bifurcation. Postoperatively he had suffered a mild groin wound infection, which had healed with antibiotics. At follow-up he complained of left calf and thigh claudication. On examination, he appeared generally well with a midline abdominal scar and a left vertical groin scar. He had good right femoral pulse but an absent left femoral pulse.

Primary and secondary prevention

Primary prevention focuses on reducing risk factors for stroke. The six most important factors are hypertension, atrial fibrillation, history of recent MI, diabetes, cigarette smoking, and alcohol abuse.Weightreduction in obese people and control of hyperlipidemia can reduce the risk of stroke (Table 13.2). stroke, previous embolism, hypertension or left ventricular function, age 75 years Patients with atrial fibrillation, aged 65-75, and with no risk factors Control of hypertension is the single most important way to reduce the risk of stroke for every 7.5-mm increase in diastolic blood pressure, the risk of stroke doubles.21 The greatest reduction in risk is in the elderly.

Kelmac Medical Answers

The answer is c. (Braunwald, 15 e, p 665.) Patients with chronic inflammatory or neoplastic disease often develop anemia of chronic disease. Cytokines produced by inflammation cause a block in the normal recirculation of iron from reticuloendothelial cells (which pick up the iron from senescent red blood cells) to the red cell precursors (normoblasts). In addition, IL-1 and interferon y decrease the production of and the response to erythropoietin. This causes a drop in the serum iron concentration and a normocytic or mild microcytic anemia. The inflammatory reaction, however, also decreases the iron-binding capacity (as opposed to iron-deficiency anemia, where the iron-binding capacity is elevated), so the saturation is usually between 10 and 20 . The anemia is rarely severe (Hb rarely less than 8.5 g dL). The hemoglobin and hematocrit will improve if the underlying process is treated. Diseases not associated with inflammation or neo-plasia (i.e., congestive heart failure,...

Acute Glomerulonephritis

(1) Hypertension (high arterial blood pressure) - mild to severe from sodium retention, water retention, or inappropriate renin release. (Renin is an enzyme released by the kidney into the blood stream, where renin has a part in raising blood pressure when blood pressure is low.) c. Treatment of Acute Glomerulonephritis. There are two goals of treatment of this infection first, relief of the symptoms and second, prevention of complications. Treatment does not require hospitalization unless oliguria, nitrogen retention, and hypertension are present. Instead, treatment requires supportive care to include the following (5) An antihypertensive (an agent that reduces high blood pressure) such as hydralazine.

Alternative Pharmacotherapy

Discussion Obesity contributes to atherosclerosis, CAD, hyperlipidemia, hypertension, and type II diabetes. Anti-obesity drugs currently on the market include orlistat and sibutramine. They are indicated lor weight loss and maintenance in conjunction with a calorie-reduced diet in patients with a body mass index 30. Orlistat is a lipase inhibitor that acts in the GI tract and blocks the absorption of dietary fat. The most common adverse effects are GI-related and include spotting, flatus, and fatty stools. Absorption of lipid-soluble vitamins (e.g., vitamin K) or medications (e.g., griseofulvin) may be decreased. Sibutramine treats obesity through appetite suppression it acts centrally by blocking serotonin and norepinephrine reuptake. Adverse effects include headache, dry mouth, constipation, insomnia, and a substantial increase in blood pressure and heart rate in some patients. Unlike the discontinued drug fenfluramine, sibutramine does not cause pulmonary hypertension or cardiac...

Items 818 through 819

A 70-year-old man complains of the sudden onset of visual loss in his right eye accompanied by a headache. He has a history of hypertension and diabetes mellitus. On physical examination, visual acuity in the left eye is 20 20 while visual acuity in the right eye is 20 90. Fun-duscopic exam shows the right disc to be pale and swollen with some hemorrhages. Which of the following is the most likely diagnosis 8-23. A 50-year-old woman is evaluated for hypertension. Her blood pressure is 130 98 mm Hg. She complains of polyuria and mild muscle weakness. She is on no diuretics or other blood pressure medication. On physical exam the PMI is displaced to the 6th intercostal space. There is no sign of congestive heart failure and no edema. Laboratory values are as follows

Types of Stress Tests

The standard echocardiogram can give the clinician invaluable information in managing the diabetic and the hypertensive patient. Quantification of valvular regurgitation and assessment of valvular stenosis and incompetence can be of value in determining appropriate therapy for hypertension (19).

The Case of Aortic Dissection

Mended, whereas the management of acute Stanford type B dissection depends on its clinical manifestation 42 . Surgical intervention is only indicated in cases of impending rupture, visceral and lower limb ischaemia, therapy-resistant hypertension and continued pain 27 . EVAR has emerged as a less invasive alternative technique for the management of complicated aortic type B dissection. EVAR significantly reduces the morbidity and mortality rates in comparison to open repair 43 . The choice of stent graft is particularly important for patients with aortic dissection. It is recommended to implant stent grafts with high flexibility and low rigidity. Customized stent grafts should be used when covering up to 20 cm of the dissected aorta 33 . In order to avoid retrograde aortic dissection, the placement of stent grafts with bare stents, hooks and barbs should be avoided. The graft over-sizing should not exceed 8-10 of the aortic diameter. Retrograde dissections are reported in up to 10 of...

Definition and Pathophysiology

Lymphedema can result from lymphatic aplasia, hypoplasia, dysmotility (reduced contractility with or without valvular insufficiency), obliteration by inflammatory, infective or neoplastic processes, or surgical extirpation (Table 10.4).Whatever the primary abnormality, the resultant physical or functional obstruction leads to lymphatic hypertension and distention with further secondary impairment of contractility and valvular competence. Lymphostasis and lymphotension lead to the accumulation in the ISF of fluid, proteins, growth factors and other active peptide moieties, glycosaminogly-cans, and particulate matter, including bacteria. As a consequence, there is increased collagen production by fibroblasts, an accumulation of inflammatory cells (predominantly macrophages and lymphocytes), and activation of ker-atinocytes. The end result is protein-rich edema fluid, increased deposition of ground substance, subdermal fibrosis, and dermal thickening and proliferation. Lymphedema, unlike...

Is Livergen Suitable For Three Months Pregnancies

The answer is e. (Braunwald, 15 e, p 479.) Data from the Metropolitan Life Tables indicate that BMIs for the midpoint of all heights and frames among both men and women range from 19 to 26 kg m2. Even at similar BMIs, women have more body fat than men. A BMI of 30 is most commonly used as a threshold for obesity in both men and women. This cutoff of 30 is based on unequivocal data. When BMIs are 25, the risk of all-cause, metabolic, and cardiovascular mortality rises, suggesting that the cutoff for obesity should be lowered. Some authorities use the term overweight (rather than obese) to describe individuals with BMIs between 25 or 27 and 30. A BMI between 25 and 30 should be viewed as medically significant and worthy of therapeutic intervention, especially in the presence of risk factors that are influenced by adiposity, such as hypertension and glucose intolerance. The desired BMI range is 18.5 to 24.9.

How does diabetes affect your kidneys

One-third of people with type 1 diabetes and 10-20 per cent of people with type 2 diabetes develop kidney disease after living with diabetes for 15 years or more. To understand how this complication develops, you need to know a little bit about the structure and function of the kidneys. The kidneys maintain the body's internal environment by controlling its fluid and electrolyte levels, and by removing its waste products. Each kidney contains approximately one million microscopic units called nephrons, which filter out waste products from the blood. Over long periods of time, high blood sugar levels damage the tiny blood vessels in the kidneys, making them thicker and clogged, and impairing the filtering ability of the nephrons. As a result, they are less able to filter wastes and impurities from the blood properly. Waste products in the bloodstream then build up to harmful levels. At the same time, some of the nutrients and proteins that should remain in the blood leak out of the...

Medications to Facilitate Bladder Emptying

Prostaglandins (PG) have been used to facilitate emptying. It is thought that these substances contribute to the bladder tone and bladder contractile activity (9,10). PGE2 and PGF2a, specifically, have been shown to cause bladder contractility. These medications, when administered intravesically, improved bladder emptying and reduced the frequency duration of postoperative urinary retention (10-16). Nevertheless, the use of PG to facilitate bladder emptying has not been completely determined. The side effects include hypotension, hypertension, pyrexia, diarrhea, and vomiting.
