Arteriosclerosis is caused by many factors. These pathogenic factors especially over-nutrition, nicotinabusus, deficiency of muscular exercise, muscular overstrain, emotional stress and concomitant basic diseases, especially arterial hypertension, diabetes mellitus and dyslipidemia are the most important points for preventive and therapeutical action. When possible the risk factors has to be eliminated, arterial hypertension, diabetes mellitus and dyslipidemia have to be treated orderly. In the pathogenesis of arteriosclerosis and atherosclerosis are known disturbances of the lipid metabolism, the blood coagulation and the metabolism of the arterial wall cells most important. Application of anticoagulants and lipid lowering medicaments did not come up to our expectations. Experiences with animal models and a double blind study (secondary prevention of myocardial infarction) have given good reason for recommending antirheumatic or as we like to say, mesenchyme suppressive drugs.

1) In 113 patients with cerebral infarction, the cause of infarction was cardiac embolism in 35, atherosclerotic thromboembolism in 45. It was either cardiac embolism or atherosclerosis but undetermined in 30. 2) Seven risk factors have been analysed. Eight patients (7 p.cent) had none of these factors. In the 105 remaining patients risk factors were: a) atrial fibrillation in 36, diagnosed in 21. Efficient treatment was applied in 1 or perhaps in 2 patients; b) High blood pressure in 39, diagnosed in 32, efficiently treated in 5; c) dyslipidemia in 42, diagnosed in 9, efficiently treated in 3; d) obesity in 50, efficiently tackled in 2; e) diabetes in 24, diagnosed in 11, efficiently treated in 2; f) hyperuricemia in 28, diagnosed in 1 with no efficient treatment; g) smoking in 44, abandonned by 1 only. 3) The high frequency of cardiac embolism is briefly commented. 4) Non diagnosis or unefficient treatment was present in a high proportion of cases. Realizing this regrettable state of affairs should result in better preventive diagnosis and treatment which, is assumed, could significantly reduce cerebral infarction.

The paper outlines the analysis of immediate and late outcomes of transcutaneous transluminal angioplasty (TTA) in 147 patients with atherosclerosis obliterans of the lower extremities. The study has revealed that age and dyslipidemia as TTA risk factors fail to affect the immediate outcomes in the early postoperative period. There is a positive correlation of the reocclusion time after TTA and the age and lipid metabolic disturbances in patients with atherosclerosis obliterans of the lower extremities in long-term periods. The paper provides strong evidence for that it is essential to correct dyslipidemias in order to make TTA results better in these patients.

In this article we have focused on the evolving pattern of nutritional management of the person with diabetes. Before the advent of insulin in 1922, it was sufficient to identify a meal plan that would keep people alive until they could be rescued from mortality due to diabetic ketoacidosis (the major killer of the era) by pharmacologic means. Now, the life expectancy of people with diabetes is close to that of the general population and focus has turned to combating the new threats of macrovascular disease and kidney failure. Over recent years the susceptibility of NIDDM patients to macrovascular events has been established and the twofold increase in risk of a heart attack in diabetic men is outshadowed by the four- to fivefold risk in diabetic women and the 13- to 17-fold greater risk in diabetics under the age of 30 years compared with their nondiabetic counterparts. The mechanism behind the susceptibility to macrovascular disease has generated a veritable plethora of investigations focusing on the atherogenic profile of diabetic dyslipidemia. Hyperinsulinemia, insulin resistance, and overtreatment of the diabetic with insulin have been claimed as contributors to the development of premature atherosclerosis. The hallmark of the diabetic dyslipidemia is the tendency to elevated VLDL triglyceride levels and the closely linked reduction in HDL cholesterol. Although there is some controversy on the relationship between triglyceride levels and the incidence of CAD, there is no doubt that HDL is an independent risk factor. It can now be safely said that elevated triglycerides are a risk factor in women and that in men elevated triglycerides constitute a risk factor if accompanied by a reduced HDL level. For these reasons, any approach to nutritional management of the diabetic must attempt not only to normalize glycemia but to make every effort to reduce the atherogenic profile. In the accompanying algorithm (Fig. 4), we consider the risk factors conducive to a reduction in life expectancy and offer a meal plan that is appropriate for the individual with diabetes. For the 80% of NIDDM patients who are obese, a diet with a reduction of 500 to 1000 kcal is in order and this may be achieved by a periodic VLCD. We examined carefully the controversy related to yo-yo dieting and support the notion that its effects in humans are not all that harmful. Ingestion of simple sugars in the high carbohydrate diet has negative effects both on carbohydrate and lipid metabolism.(ABSTRACT TRUNCATED AT 400 WORDS)

Cardiovascular disease constitutes an expanding problem in the elderly because of the increasing size of the aged population. Atherosclerosis, hypertension, and diabetes are responsible for the predonderance of cardiovascular disease, which causes 70% of all deaths beyond age 75. Coronary heart disease (CHD) is the most common and most lethal cardiovascular event in both sexes, exacting a large toll in disability and deteriorated quality of life in old age. Unrecognized myocardial infarctions are especially common and are as serious as symptomatic infarctions. beyond age 65, women are as vulnerable to cardiovascular death as men. The predisposing modifiable risk factors for coronary disease, stroke, peripheral arterial disease, and cardiac failure are similar in young and old and in men and women. These include hypertension, dyslipidemia, impaired glucose tolerance, physical indolence, and cigarette smoking. An attenuated risk ratio for some risk factors is offset by a greater incidence of cardiovascular events in advanced age so that the attributable risk and the potential benefit of treatment rise with age. Because the major risk factors predict CHD as efficiently in the elderly as in the young, and the decline in cardiovascular mortality has included the elderly, preventive efforts in the elderly may have substantial potential benefit. At advanced age, total cholesterol levels are considerably higher in women than in men. Some 10 million elderly, two-thirds of whom are women, may require investigation and treatment for elevated lipid levels, as determined by National Heart, Lung, and Blood Institute (NHLBI) guidelines. Because of the preponderance of women in the elderly population, trials of the efficacy of correcting risk factors in general, and lipids in particular, should include women.

The coagulative system has an important role on haemodialysis and on atherosclerosis genesis; in particular the platelets are key elements of the coagulation and of atherosclerosis phenomena. Alterations of the coagulative system and increase risk of developing atherosclerosis are reported in the aging. We in this paper, report the results obtained studying the influence of the interaction between the elderly and dyslipidemia on the coagulative system in haemodialyzed patients. The obtained data showed that the hypertriglyceridaemia in interaction with the elderly accelerates and increases platelet aggregation after stimulation by ADP, Epinephrine and Collagen. So, it is important to consider hypertriglyceridaemia and age as thrombogenic factors and atherosclerosis accelerating factors in haemodialyzed patients.

Insulin resistance and consecutive hyperinsulinemia in individuals with the metabolic syndrome are associated with dyslipidemia. This latter is characterised by hypertriglyceridemia and a diminishment of high-density lipoprotein (HDL) cholesterol in the plasma. In severe forms of insulin resistance, low density lipoprotein (LDL) cholesterol may also be elevated. Hypertriglyceridemia is due to an increase in the rate of synthesis of very low density lipoproteins (VLDL) in the liver, and a reduction in their breakdown by the lipoprotein lipase in non-hepatic tissue. Changes in VLDL metabolism are associated with a reduction in HDL concentrations. In addition, direct effects of insulin on the lipid metabolism have been described. Changes in lipid metabolism due to insulin resistance and hyperinsulinemia may be of significance for the atherosclerosis risk in patients with the metabolic syndrome.

Ten patients have been studied for lipidic behaviour during hemodialysis using as anticoagulant heparin and prostacyclin. Hearing has been administered at infusion rate of 2000 U/h and prostacyclin in 5 ng/kg/min. Lipidic behaviour (before and after hemodialysis) has been studied for apolipoproteins A and B, total serum cholesterol and serum triglycerides, HDL-cholesterol, lipoprotein. Total serum cholesterol/HDL-cholesterol, apolipoproteins A/apolipoproteins B, apolipoproteins A/HDL-cholesterol ratios have been also studied. Our findings show that heparin produces acute changes in lipidic behaviour after hemodialysis and suggest that administrations may contribute to lipidic derangement of uremic dialytic patient while heparin free dialysis (prostacyclin infusion) doesn't show lipidic derangement after dialytic treatment. Prostacyclin infusion suggests that may be a useful anticoagulant and therapeutic drug especially in uremic dialytic subject with high atherosclerosis involvement, dyslipidemia and arterial hypertension.

Non-insulin-dependent diabetes (NIDDM) has long been recognized as being associated with a cluster of disorders including obesity, hypertension, dyslipidemia, and atherosclerotic heart disease. It was only recently, however, that Reaven, DeFronzo, and Ferrannini with techniques to quantitate insulin resistance suggested that this represents a common factor in this group of disorders and that hyperinsulinemia resulting from insulin resistance could be the cause of the hypertension, dyslipidemia, and atherosclerosis. The names syndrome X or the insulin-resistance syndrome have been used to identify this pathological entity, and considerable investigations have been done and are in progress to establish whether or not these coexisting disorders represent an as yet unexplained association of cardiovascular risk factors or if, indeed, insulin resistance and hyperinsulinism represent the primary cause for most of the other disorders. To paraphrase a philosophical comment, if syndrome X did not exist, we probably would have had to invent it. In addition to the intellectual satisfaction of being able to "lump" these diverse ills under a single etiology, the main value of grouping these disorders as a syndrome is to continually remind physicians that the therapeutic goals are not only to correct hyperglycemia in NIDDM but also to manage the elevated blood pressure and dyslipidemia that cause cerebrovascular and cardiac morbidity as well as mortality in these patients. Having a syndrome X reduces the fragmentation of medical care among subspecialties and decreases the likelihood of prescribing drugs that correct hypertension but raise lipids or drugs that lower lipids but raise blood glucose. Finally, it encourages the selection of drugs that reduce hyperglycemia without increasing insulin secretion and to the development of new drugs for this purpose. Unfortunately, the concept of insulin resistance with hyperinsulinism being a cause of the other associated disorders is still unproved but continues to be open to experimental investigation. The remainder of this article reviewed the use of sulfonylureas in the management of NIDDM, discussed new molecular and cellular mechanisms by which they promote insulin secretion, and reviewed the controversy as to whether an extrapancreatic action contributes to their glucose-lowering effects in NIDDM. A closing section listed some other oral drugs that can lower blood glucose without stimulating the pancreatic beta cell. Their insulin-sparing hypoglycemic effect makes them potentially useful in NIDDM therapy, particularly if the fundamental premise of syndrome X is substantiated, which implicates hyperinsulinemia as contributing to the morbidity and mortality from atherosclerotic vascular disease.

Accelerated atherosclerosis is a major complication of long-term diabetes mellitus, and this is partly due to associated abnormalities of lipoprotein metabolism. Hypertriglyceridemia is usually due to poorly controlled diabetes and responds to improved glucose control. Hypercholesterolemia is usually not related to poor diabetic control and should be treated with a cholesterol lowering diet and drugs according to the National Cholesterol Education Program guidelines. Low HDL-C is common in NIDDM and does not fully return to normal with improved diabetic control. Dyslipidemia in diabetics should be aggressively identified and treated to decrease cardiovascular risk.
