Our way to prevention is to find a list of traits known to be predictors of elevated blood pressure. This list of predictors offers means for the early identification of susceptibile persons. Years of experience in preventive work indicate that such identification is always useful for developing preventive programmes, since it gives a focus for action (5). Most of the predictors show possible ways in which action could be directed towards prevention of hypertension and reduction of elevated blood pressure. We will focus on salt, control of obesity, physical exercise, and meditation. We would like to discuss preventive aspects of hypertension and the possibility of treating with other methods than drugs.

Seven hundred and fifty asymptomatic European subjects aged 16 to 69 years from an urban general practice were screened for various coronary risk factors. Required information was completed for 98.9 percent of the total sample. The incidence of individual risk factors in males and females respectively were: smoking, 52.8 percent and 45.6 percent; obesity, 26.9 percent and 30.9 percent; definite hypertension, 5.6 percent and 4.0 percent; borderline hypertension, 5.3 percent and 5.1 percent; hyperlipidaemia, 12.8 percent and 8.0 percent; impaired glucose tolerance, 1.1 percent and 1.3 percent. Respective figures for males and females with regard to numbers of risk factors present were: one or more risks present, 68.5 percent and 66.9 percent; two or more, 26.5 percent and 23.5 percent; three or more, 8.0 percent and 4.5 percent; four risk factors present, 1.6 percent and 0.3 percent.

1. Variables involved in the genesis of hypertension in male broad-breasted white turkeys include social environment, obesity and high salt intake. 2. The hypertension is characterized by low plasma renin activity and, with increasing age, normal to high plasma aldosterone. 3. Medionecrosis of the abdominal aorta is a common pathological finding. 4. The absence of atherosclerotic plaques is probably related to the high concentrations of alpha-lipoproteins.

Two-hundred-and-forty-eight full-blood tribal Aborigines from the West Kimberley region of Western Australia were surveyed for the prevalence of coronary heart disease, and compared with the known prevalence in whites in the country town of Busselton, WA. The prevalence was found to be greater among the Aborigines, with 7% of men, and 11% of women being found to have "probable" coronary heart disease. Seven per cent of the population had electrocardiographic changes characteristic of frank ischaemia. The major risk factors contributing to this high prevalence were hypertension, diabetes mellitus, and obesity. Thirty-seven per cent of the Aborigines were hypertensive, and 17% had diabetes mellitus.

An increasing incidence of endometrial cancer caused by a higher life expectancy and a number of other facters (i.e. obesity, diabetes, hypertension, lower pregnancy rate) as well as the unfavorable location for early detection when compared with cervical cancer has initiated this review in order to single out women with increased risk. Clinical characteristics of patients with endometrial cancer represented by age, menstrual disorders, reduced fertility, obesity, diabetes, hypertension, hirsutism, hyperplasia of the ovarian stroma or hilus cells in connection with an increased oestrogen effect in the vaginal smear and proliferative changes of the endometrium can be explained by extraglandular respectively peripheral aromatization of androgens to oestrogens, particular by the conversion of androstenedione to oestrone. This is supported by an increased plasma oestrone/oestradiol-ratio and increased conversion rate with age and overweight. In vivo- and in vitro-investigations have demonstrated the participation of adipose tissue in peripheral oestrogene production. The compiled data point towards the importance of the extraglandular oestrone production for the etiology of endometrial cancer by effecting the endometrium over a long period of time. The counter action of the normally cyclic changes of oestradiol and progesterone is lacking. Therefore, a dysoestrogenic effect of oestrone upon the endometrium can be fully effective, depending on the hormone receptor content of the respective endometrium. Based upon these data including recent publications, pre- and postmenopausal oestrogen therapy has to be critically reevaluated.

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 therapy of gout is discussed taking into consideration the concomitant diseases occurring significantly frequently in patients with gout: Hypertension, uric acid-nephrolithiasis, hyperlipoproteinaemia, obesity, premature arteriosclerosis as well as diabetes mellitus. In contrast to other opinions the authors are of the opinion that the dietetic treatment is furthermore of essential importance. It is referred to the still allowed sufficiently great number in the supply of nourishment, in which cases, however, the limitations in the supply of calories, protein or purin bodies, respectively, lipid and carbohydrate do not remain unmentioned. The propositions for the medicamentous treatment essentially correspond to the central therapeutic recommendations. For the acute attack of gout, however, following to the international experiences, the colchicine therapy is more emphasized again. The medicamentous therapy of the asymptomatic hyperuricaemia is to be included into the considerations after full exhaustion of all dietetic and other possibilities in constant increase of the serum-uric acid-level more than 8 mg/dl.

The seeds of premature coronary heart disease are often sown in childhood and it is the developing arteries of children which are the most susceptible. Paediatricians and all who work with them have the earliest and most promising opportunities for prevention. Coronary protection can be added to the potential advantages of breast feeding and to ensure appropriate fatty acid balance throughout weaning. It is reasonable to accept the strong consensus of opinion on diet reflected in the reports of the eighteen national committees. They are: to reduce total fat intake to 30-35% of the energy, to restrict consumption of saturated fat, cholesterol, sugar, and salt, to increase unrefined carbohydrate and polyunsaturated fat, and to maintain a P/S balance of 1.0-1.5:1. Food is the fundamental coronary risk factor, but others may add insult to injury. Smoking, hypertension, obesity, lack of exercise, and stress, each of which is related to behaviour, may start in childhood. Smoking doubles the overall risk CHD and increases it ten times in males under 45 years old. Good habits, including food preferences and eating patterns learned early, are those most likely to be continued. School meals require and should match revised nutritional education. The co-operation of the food industry is essential and can be anticipated, but it requires a clear lead by paediatricians. The nutritional advice should come from the medical profession. Every contact with children and their parents provides an opportunity for enquiry and giving advice.

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.
