A 38-year-old female was admitted to our hospital because of dyspnea. The diagnosis of total lipodystrophy was made by following findings: (1) gaunt appearance; (2) insulin-resistant diabetes mellitus; (3) hyperlipidemia; (4) fatty liver. Chest X-ray demonstrated cardiomegaly, pulmonary edema and pleural effusion. Echocardiogram was characterized by left ventricular hypertrophy with asymmetrical septal hypertrophy and left ventricular dysfunction. Renal biopsy revealed focal glomerulosclerosis. We reported a patient with total lipodystrophy combined with heart failure and renal failure, which have been rarely associated with the disease.

It is generally acknowledged that hypertension is associated with an increased risk of cardiovascular morbidity and mortality, and that lowering elevated blood pressure is effective in reducing that risk. However, hypertension is more likely to cause cardiovascular disease in those with additional risk factors, such as cigarette smoking, hyperlipidemia, diabetes mellitus, hypokalemia, loft ventricular hypertrophy, or electrocardiographic abnormalities. The evidence to date indicates that not all patients with mild hypertension need to be treated with drugs; not all of those receiving drug therapy should be treated with the same drugs; and the benefit of the same degree of reduction in blood pressure may not be equivalent for different drugs. The use of traditional step 1 diuretic therapy is not uniformly appropriate. As an alternative, the vasodilator prazosin can be effective as monotherapy in the treatment of mild hypertension, and its addition to diuretic or beta blocker therapy appears to blunt or prevent the adverse effects of those agents on lipid levels. Since prazosin therapy is least likely to worsen existing risk factors or precipitate their occurrence, it should enhance the benefit of blood pressure reduction in delaying or preventing cardiovascular disease.

The treatment of high blood pressure with beta-blocking and other antihypertensive agents has been associated with a decrease in the incidence of stroke, progression of hypertension, heart failure, left ventricular hypertrophy, retinopathy and renal failure. Although hypertension increases the risk for developing coronary disease, the risk is heightened markedly if coexistent hyperlipidemia, smoking or glucose tolerance is present. Thiazide diuretics, primarily used as antihypertensive agents, compromise glucose tolerance and are associated with increases in plasma cholesterol, triglycerides and low density lipoprotein levels. Nonselective and beta 1-selective beta blockers have also been associated with increases in plasma triglycerides and very low density lipoproteins, as well as with decreases in high density lipoprotein levels. The effects of various antihypertensive agents on lipid levels, lipid metabolism, carbohydrate metabolism, left ventricular size and atherogenesis are discussed.

Whether or not obesity per se is an independent risk factor remains controversial. However, a variety of studies have shown that obesity precipitates certain well-known risk factors, such as glucose intolerance, hyperlipidemia, hyperestrogenemia, hypertension, and left ventricular hypertrophy. Distribution of adipose tissue also seems to influence cardiovascular risk; patients with predominantly male-pattern obesity exhibit more profound risk for cardiovascular disease.

To assess the potential effect of hypertension on the results of thallium-201 stress imaging in patients with chest pain, 272 thallium-201 stress tests performed in 133 hypertensive patients and 139 normotensive patients over a 1-year period were reviewed. Normotensive and hypertensive patients were similar in age, gender distribution, prevalence of cardiac risk factors (tobacco smoking, hyperlipidemia, and diabetes mellitus), medications, and clinical symptoms of coronary disease. Electrocardiographic criteria for left ventricular hypertrophy were present in 16 hypertensive patients. Stepwise probability analysis was used to determine the likelihood of coronary artery disease for each patient. In patients with mid to high likelihood of coronary disease (greater than 25% probability), abnormal thallium-201 stress images were present in 54 of 60 (90%) hypertensive patients compared with 51 of 64 (80%) normotensive patients. However, in 73 patients with a low likelihood of coronary disease (less than or equal to 25% probability), abnormal thallium-201 stress images were present in 21 patients (29%) of the hypertensive group compared with only 5 of 75 (7%) of the normotensive patients (p less than 0.001). These findings suggest that in patients with a mid to high likelihood of coronary artery disease, coexistent hypertension does not affect the results of thallium-201 exercise stress testing. However, in patients with a low likelihood of coronary artery disease, abnormal thallium-201 stress images are obtained more frequently in hypertensive patients than in normotensive patients.

The effect of hypertension, hyperlipidemia, and the combination of both on acute and chronic myocardial ischemia were evaluated in a total of 30 male rabbits. After preliminary hypertension and/or hyperlipidemic load by loading of the abdominal aorta and/or cholesterol feeding, acute ischemia was produced by clipping of the left coronary artery. The banding produced elevation of carotid arterial pressure and left ventricular hypertrophy. Cholesterol feeding resulted in severe atheromatous changes in all sizes of coronary arteries. The intimal thickening was due to foam cell accumulation in all arteries examined. Animals pretreated with the combination of hypertension and hyperlipidemia displayed the most severe cardiolmegaly with advanced coronary atherosclerosis and chronic ischemic lesions of the myocardium, i.e., perivascular patchy fibrosis in the subendocardial area. Furthermore, electron microscopic detection of ultrastructural myocardial damage, involving glycogen depletion, sarcoplasmic edema, mitochondrial swelling, and contractile abnormalities, was also most frequent in this group. These changes were quantitated using the ischemic score. These results confirm the hypothesis that fatal ischemic injuries may occur clinically in human hearts with coronary insufficiency due to coexistence of hypertensive cardiomegaly and severe coronary atherosclerosis. They offer a model for further study of these combined effects.

The National High Blood Pressure Education Program has released three Joint National Committee reports and a task force report on the detection, evaluation, and treatment of high blood pressure. Like its predecessors, the 1988 Joint National Committee report was developed using the consensus process; it is based on the latest scientific research and reflects the state of the art regarding hypertension management. This report updates findings of previous reports in several respects: it broadens the step-care approach to provide more flexibility for clinicians; encourages greater patient involvement in the treatment program; emphasizes a consideration of the quality of life in the management of patients; and addresses the cost of care. It also provides more emphasis on control of other risk factors for cardiovascular disease; includes a discussion of the new cholesterol guidelines; recommends a reduction in alcohol consumption; and discusses the use of calcium and fish oil supplementation. This document expands earlier reports on special populations, including blacks and other racial and ethnic minority groups, young and elderly patients, pregnant patients, surgical candidates, and hypertensive patients with cerebrovascular disease, coronary artery disease, left ventricular hypertrophy, congestive heart failure, peripheral vascular disease, renal disease, chronic obstructive pulmonary disease or bronchial asthma, gout, diabetes mellitus, and hyperlipidemia. The report also updates previous drug tables to include new drugs, revised recommended doses of some drugs, and drug interactions. Consideration of step-down therapy after blood pressure has been controlled is suggested. This report is intended as a guide for practicing physicians and other health professionals in their care of hypertensive patients and as a reference for those participating in the many community high blood pressure control programs throughout the country.

Out of 512 recipients of kidney allotransplants 36 patients exhibiting cardiovascular complications (coronary artery disease, cerebrovascular accident, aneurysm of aorta, peripheral arterial occlusions) were compared with an age and sex matched group of recipients without cardiovascular problems. The following significant differences were observed in the study group versus the controls: high systolic and diastolic blood pressure, longer duration of hypertension before renal allografting, higher serum concentrations of cholesterol, triglycerides and uric acid, and an increased incidence of left ventricular hypertrophy and preexisting cardiovascular disease. No differences were found between the two groups as regards smoking habits, overweight, hyperparathyroidism, duration of hemodialysis treatment and type of kidney disease. Diabetes mellitus, family history of cardiovascular complications and hypertonic alterations of the eye fundus were more frequent, but not to a statistically significant extent, in the study group as compared to control patients. These findings show the need for regulation of blood pressure, hyperlipemia and hyperuricemia to ensure successful longterm rehabilitation after kidney allografting.

From March 1960 through January 1968, 71 patients underwent operations for renovascular hypertension at our center. There were three operative deaths in 94 procedures. Primary nephrectomy was performed in 26 patients. Attempted revascularization of 62 kidneys was successful in 46 (74%). In 13 (87%) of the 15 cases considered operative failures, the patients underwent either secondary nephrectomy (11) or repeat revascularization (two). Based on the results of the final operation, initial blood pressure response (1 to 6 months postoperatively) in the surviving patients indicated 44% cured (30 patients), 40% improved (27), and 16% unchanged (11). The sequential clinical, functional, and anatomic follow-up evaluations to time of death or to date are available in 66 of the 68 patients (97%) who survived operation and form the basis of this report. Fifteen- to 20-year arteriographic follow-up in 16 patients revealed one late neointimal anastomotic stenosis and an additional three aortic suture line false aneurysms in Dacron aortorenal grafts. During this 15- to 23-year follow-up, 71% of atherosclerotic (AS) patients and 23% of fibromuscular dysplasia (FMD) patients died. Cardiovascular (CV) morbid events occurred in 77% of AS patients and in 19% of FMD patients. The cumulative incidence of death and CV morbid events during follow-up is examined by Kaplan-Meier life tables and Cox's proportional hazards regression analysis in these respective groups to identify preoperative markers predictive of longer event-free survival in relation to blood pressure benefit by operation (for example, focal vs. diffuse AS, presence of cerebrovascular disease, ischemic heart disease, left ventricular hypertrophy seen by electrocardiography, azotemia, smoking, diabetes, and hyperlipidemia).(ABSTRACT TRUNCATED AT 250 WORDS)

The introduction of continuous nocturnal enteral glucose feeds and uncooked cornstarch has improved the prognosis for patients with the hepatic glycogen storage diseases. An increasing number of patients are surviving into adulthood in better health, but still at some medical cost. In this review we examine bone mineralization, renal function, hepatic tumours, and vascular endothelial function in GSD I and cardiac function in GSD III. All females over the age of 5 years with GSD I, III, VI and IX had morphologically polycystic ovaries. Thirteen adult GSD I patients have been studied, and been found to have poor bone mineralization and marked renal glomerular and tubular dysfunction. More than half of these patients also had focal hepatic lesions on sonography and yet vascular endothelial function was preserved in the face of hyperlipidaemia. In 12 GSD III patients, one had a focal hepatic lesion and 6 had pronounced left ventricular hypertrophy, although cardiorespiratory function was normal. These data emphasize the multisystem nature of these disorders and highlight the need for careful longterm follow-up.
