Males and females 30 years and over were invited to participate in a community health screening project. Thirty percent of the target population did so. They were questioned on personal and family medical history, smoking and drinking habits and occupation. Height, weight, blood pressure and ECG were recorded. Haemoglobin, blood sugar, cholesterol and uric acid were analysed. Overweight, hypertension and hypercholesterolaemia were common. About one third of males and females smoked but 23 percent of males had given up smoking at the time of the survey.

The prevalence of clinical and sub-clinical occlusive arterial disease and of risk factors implicated in the pathogenesis of arteriosclerosis was assessed in 21 patients with chronic renal failure, 27 on maintenance haemodialysis and 51 renal allograft recipients. Clinical occlusive arterial disease was present in 27 patients, and sub-clinical arterial disease in 34. Myocardial infarction, cerebral thrombosis and lower limb arterial thrombosis had occurred only in the transplant recipients; these patients had, however, been followed for a longer period of time than the other two groups. In the allograft recipients, the cumulative incidence of any occlusive arterial disease was 416 per 1000, and that of coronary heart disease was 267 per 1000 at six years. Hypertension was present in 76 per cent of patients prior to renal replacement therapy. Following institution of definitive therapy, hypertension was of shorter duration and less common in haemodialysis patients than in renal transplant recipients. Uraemic and haemodialysis patients with occlusive arterial disease had required antihypertensive medication for significantly longer than those free of arterial disease. Transplant recipients with hypertension had a greater mean serum creatinine, were receiving a larger maintenance dosage of corticosteroids and less frequently had undergone prior bilateral nephrectomy than those transplant patients without hypertension. Serum lipid levels were elevated in 62 per cent of patients. In the uraemic and haemodialysis patients hypertriglyceridaemia was the predominant abnormality while in the transplant recipients combined hypertriglyceridaemia/hypercholesterolaemia was more frequent. Despite regular aluminium hydroxide therapy 81 per cent of uraemic and haemodialysis patients had a calcium X phosphate product higher than normal. Arterial and/or soft tissue calcification as demonstrable in 20-38 per cent of patients within each group, but could not be related to the calcium X phosphate product of radiographic evidence of hyperparathyroidism. Glucose intolerance was present in 71 per cent of the uraemic and haemodialysis patients and 33 per cent of the transplant recipients. Hyperuricaemia, cigarette smoking, obesity and a sedentary existence were also prevalent. The majority of patients had several risk factors implicated in the pathogenesis of arteriosclerosis. Occlusive arterial disease is a major problem in patients with end stage renal disease, being no less common after transplantation than with long-term maintenance dialysis. The aetiology is multifactorial.

The incidence of cardiovascular risk factors was studied in 83 renal transplant recipients: 84.3% showed at least one cardiovascular risk factor, hyperuricaemia was found in 42.2%, hypertension in 39.7%, hypercholesterolaemia in 31.3%, hypertriglyceridaemia in 27.7%, diabetes mellitus in 19.3%, obesity in 14% and nicotine abuse in 13.2% of the patients. Patients aged from 30 to 39 and 40 to 49 showed a mean incidence of 2.7 and 2.9, respectively out of the 7 investigated cardiovascular risk factors. The results demonstrate that renal transplant patients are a high-risk group for the development of degenerative cardiovascular diseases.

This paper reviews and discusses the evidence supporting the involvement of defective fibrinolysis in the pathogenesis of atherosclerosis, with emphasis on diabetes mellitus. According to the literature, defective fibrinolysis has been observed in association with virtually every major "risk factor" for coronary heart disease, including diabetes mellitus, hypercholesterolemia, hypertriglyceridemia, hypertension, obesity, cigarette smoking and lack of physical exercise. The interrelationships between disturbances in carbohydrate and fat metabolism and fibrinolysis are considered. Attention is drawn to the need for increased clinical attention to the potential role of defective fibrinolysis in atherogenesis, and periodic assessments of the fibrinolytic status are suggested as a promising approach toward early recognition of atherosclerotic tendency and risk. The judicious use of physiologic, dietary and pharmacologic means to correct defective fibrinolysis prophylactically and for the treatment of some forms of atherosclerosis is advocated.

Estrogen replacement in menopause should be used for specific symptoms such as ovarian failure, hot flushes, vaginal atrophy, atrophy of the vulva, and atrophic urethritis. The dose should be as low as possible to be effective and perscribed for as short as time as possible, since there are possible risks of uterine cancer, breast cancer, increased blood pressure, gallstones, deep vein thrombosis, and thromboembolism. Estrogens should be administered to provide the maximum benefit with the minimum risk involved. Estrogens should not be given to patients with known contraindications such as: suspected breast or uterine cancer; undiagnosed genital bleeding; Dubin-Johnson syndrome; acute hepatic disease; previous or present thromboembolism; or severe thrombophlebitis. Careful evaluation should be made before administering estrogen to women with uterine myomata, hyperlipidemia, hypercholesterolemia, sevare varicose veins, chronic hepatic dysfunction, diabetes mellitus, porphyria, or severe hypertension.

For the first time in mass studied of populations the author applied a REG method for the assessment of different risk factors in cerebrovascular disorders. REG changes were studied in 1446 individuals (males from 40-59 years and females from 50-59 years) living in 2 districts of Moscow in relation to the influence of age, sex, arterial hypertension, smoking, excessive weight and hypercholesterolemia. A certain specificity of changes depending upon the acting factors was established. The highest REG changes were connected with advent of age, arterial hypertension and smoking. The achieved results make it possible to recommend REG for use in epidemiological studies. This method may also facilitate a detection of pathological changes in the brain due to the action of unfavourable factors.

In 240 patients with peripheral circulatory disorders (Fontaine Stage II) who had participated in intensive physiotherapeutic interval training daily for 6 weeks between October 1974 and July 1976, it was established that the therapeutic results were not related to age or sex. The "risk" factors of smoking, diabetes mellitus, hypertriglyceridemia, hypercholesterolemia and hyperuricemia individually show no connection with the results. Only overweight, hypertension and coronary heart disease appear to have an unfavorable influence. It is distinctly recognizable that the more risk factors there are combined in a patient with intermittent claudication, the less chance he has of success in physiotherapeutic vessel training.

1477 employees of a large industrial firm in Munich (868 males and 609 females, aged 40-59) were examined for coronary heart diseases risk factors. Among males, hypercholesterolemia predominates with a distribution of over 40%. Every fifth male has high blood pressure or is a heavy cigarette smoker. The females under 50 years of age clearly show fewer risk factors, but toward 60 years they exceed the males in frequency of some factors. Among women, too, the top risk factor is cholesterol, followed by overweight and high blood pressure. On the average, about 8% of the men and women have a preclinical or manifest diabetes. About every fifth male examined and every seventh female can be considered as especially endangered by the presence of 3 or more risk factors.

1. Using the xenon-133 washout technique, the renovascular response to intrarenal infusions of 3 and 30 mumol/min noradrenaline in four baboons with dietary-induced hypercholesterolaemia was measured. 2. The degree of reduction in cortical blood flow rate during an intrarenal infusion of 3 mumol/min noradrenaline in the four hypercholesterolaemic baboons was not significantly different from that in normocholesterolaemic baboons. However, a significant difference in the degree of reduction in cortical blood flow rate was found with the 30 mumol/min noradrenaline infusion (P less than 0.05). 3. The mean arterial blood pressure of the four animals was significantly higher (P less than 0.001) than the mean blood pressure in baboons used in this laboratory for other experiments. 4. These results have shown that baboons with dietary-induced hypercholesterolaemia have an enhanced renovascular sensitivity to exogenous noradrenaline. However, the possibility that this enhanced sensitivity was due to the associated hypertension cannot be excluded.

An optimal diet cannot yet be defined. If we knew what an optimal diet was, additional research in nutrition would not be necessary. There is abundant evidence, however, that the usual American diet is not optimal and adequate reason to recommend modification. Current dietary recommendations were developed to prevent the occurrence of nutritional deficiency disease in the 1930's and 1940's. They have been largely successful. They were made, however, before any knowledge was available about the effects of diet upon chronic disease which now represent the primary health problems of the United States. Large amounts of data are available indicating the kids of recommendations which should be made to control hypercholesterolemia--a primary risk factor of coronary artery disease. These kinds of data together with less information upon diet and cancer, hypertension, obesity, diabetes, etc. lead to sensible and consistent dietary recommendations to moderate the dietary practices of most Americans.
