The purpose of the survey was to study the time course of the leading CHD risk factors in an open population of men born in 1916-1935 during a prolonged prospective study and to specify CHD interrelationship with new cases of disease and a course of nonfatal CHD. A population of 5000 males from one of the Leningrad districts was examined with an interval of 7.6 yrs. The first screening included 3907 persons, the repeated screening 2096. In the period of observation the number of persons with the absence of leading risk factors decreased (from 11.5 to 9.6%), the frequency of arterial hypertension (AH) increased (from 32.9 to 42.3%), the proportion of examinees with atherogenic dyslipoproteinemia (DLP) remained the same. By the results of the first screening in 50% of the persons with atherogenic DLP the blood lipid composition in 7.6 yrs returned to normal; AH persisted in 80% of the examinees. The presence of the 3 leading risk factors during the first and second screenings was accompanied by the highest frequency of stable CHD and the highest index of new cases of disease.

An epidemiological survey was conducted among men aged 40 to 59 to study interrelationships of the nutritional patterns in 2 ethnic groups of population and the prevalence of CHD and risk factors of its development. The nutritional habits of the indigenous Kirghiz population in the city of Frunze differed significantly from those of the alien population (Russians, Ukrainians, etc.) and were characterized by a higher consumption of proteins and complex carbohydrates. Nutrition of the alien population included mostly simple carbohydrates: sugar, fat and monounsaturated fatty acids. Coronary heart disease, arterial hypertension, smoking, excess body mass, low physical activity were equally common among the Kirghiz and Europeans. Hypercholesterinemia was noted more frequently in Europeans whereas hypertriglyceridemia was more common among the Kirghiz.

A three-decade examination of the prevalence, incidence, secular trends, and prognosis of cardiac failure in the Framingham Study provides insights into its epidemiology. Annual incidence of CHF is observed to increase from 3 to 1000 at ages 35-64, to 10 per 1000 at ages 65-94. There is a slight male predominance, owing to a higher rate of coronary disease, which conferred a fourfold risk of cardiac failure. Most cardiac failure is on the basis of long-standing hypertension or CHD. Silent infarctions were as predisposing for CHF as symptomatic MIs surviving 1 year. Hypertension is a major predisposing factor that at least triples the CHF risk, the systolic component being more predictive than the diastolic component. Correctable predisposing risk factors for CHF include: elevated blood pressure, impaired glucose tolerance, elevated cholesterol, low HDL-cholesterol, obesity, and a high hematocrit. Risk factors reflecting deteriorating cardiac function also were highly predictive, including: an enlarged heart, poor vital capacity, sinus tachycardia, and ECG-LVH. Commonly encountered ECG abnormalities such as intraventricular block, nonspecific repolarization abnormality, and ECG-LVH are all associated with a substantial risk of CHF. ECG-LVH carries a higher risk than x-ray enlargement. Sudden death was a common feature with CHF, occurring at 5 times the general population rate, even excluding those with overt CHD. Using the standard cardiovascular risk factors (age, systolic blood pressure, cholesterol, glucose, cigarettes, and ECG-LVH) jointly, it is possible to identify one tenth of the population from which 40% of CHF events evolve, in the absence of interim CHD or RHD.

Prior to the start of the intervention activities in the five study regions of the German Cardiovascular Prevention Study (GCP), health surveys of representative samples of the population (25 to 69 years) were carried out between 1984 and 1986. In all, 11,527 persons participated in the study. Important socio-structural differences existed between the five study regions. An ecological analysis relating social class characteristics to the prevalence of CHD-risk factors did not show any significant findings. However, a pooling of the data of the five study regions resulted in the demonstration, for both sexes, of a significant association of social class with cigarette smoking and overweight. Hypertension and hypercholesterolemia were not related to social class. The proportion of persons with three or more CHD-risk factors was clearly higher in lower social classes. These findings point to the need for risk factor intervention strategies focusing more on the lower social classes in order to achieve more adequate prevention of coronary heart disease.

Changes in the activity of blood monocytic cholesterol esterase in men with major CHD risk factors (dyslipoproteinemia, arterial hypertension, excessive body mass) were described. Standard methods of epidemiological survey and a radionuclide method to determine cholesterol esterase activity applied to a representative sampling (195 persons) have shown that enzymatic activity was growing with age. In examinees with hyperlipoproteinemia of type IIa and IIb the activity of cholesterol esterase was decreased, and in persons with excessive body mass it was increased. In combination of 2-3 CHD risk factors significant differences in enzymatic activity were undetectable.

Alcohol consumption practice was studied by a method of interview in an unorganized male population aged 40 to 59 investigated by a program of multifactorial CHD prevention. The frequency of spreading of this habit and its intensity were determined. The frequency of alcohol consumption was decreased with age and was associated with the examinees' educational level. Persons consuming alcohol more frequently had raised arterial hypertension and smoked. These factors increased the risk of CHD development which was confirmed by a 5-year prospective study of mortality. Alcohol abusers were characterized by higher rates of general mortality, including that from cardiovascular diseases, traumas and accidents, in particular, alcoholic intoxication.

The paper is concerned with some data on the time course of indices of carbohydrate metabolism and lipid spectrum in patients with type II diabetes mellitus with concomitant CHD or arterial hypertension during therapy with mean doses of propranolol. The course treatment with propranolol resulted in the deterioration of carbohydrate metabolic indices and unfavorable shifts in the lipid spectrum of some patients. Patients on insulin therapy might demonstrate a significant decrease in the blood sugar level after physical exercise. The results obtained indicate the necessity of control over indices of carbohydrate and lipid metabolism in patients with type II diabetes mellitus during propranolol therapy.

A massive body of scientific evidence from clinical, experimental, pathological and epidemiological studies as well as from risk factor intervention trials and community studies has emerged until the 1980s; interpreted as a whole it leaves no more doubt about the major role of hyperlipidaemia, hypertension, cigarette smoking and some other modifiable factors in the aetiology of atherosclerosis and CHD, and about the great potential for primary prevention of CHD. In response to this challenge, the World Health Organization Expert Committee in its report in 1982 outlined the general principles and strategies for the primary prevention of CHD, and these principles and strategies have then been reinforced and further developed toward practical action plans by international and national experts groups. The perspectives for the primary prevention during the future decades may be envisaged to include: (1) further strengthening of preventive action in those countries with high or relatively high CHD rates in which favourable changes in life-styles and risk factor levels are already going on and CHD rates are declining; (2) development and implementation of effective plans for preventive action in those countries with high or relatively high CHD rates in which these rates are not yet declining or even increasing, and (3) development and implementation of effective plans for a real primordial prevention of CHD, i.e., preventing the appearance of unhealthy life-styles and elevated risk factor levels, in those developing countries in which CHD threatens to emerge in connection with socio-cultural changes toward urbanization and industrialization.

The impact of risk factors for sudden and non-sudden coronary death was investigated in 3,589 Finnish men aged 40-59 years at entry from a prospective population survey. During a mean follow-up time of 11 years, 234 coronary deaths occurred, 150 of which were sudden, i.e. ensuing within 1 hour of the onset of symptoms. The severity of the manifestations of CHD at baseline investigation appeared to be a powerful predictor of sudden coronary death. Smoking and high serum cholesterol were significant predictors of sudden coronary death. High serum cholesterol was an equally significant predictor of sudden and non-sudden coronary death. High blood pressure did not appear to significantly increase sudden coronary death but increased the incidence of non-sudden death significantly. Obesity and diabetes did not appear to be independent risk factors for sudden coronary death. Smoking and high serum cholesterol were significant risk factors for sudden coronary death in men with manifestations of coronary heart disease. The results suggest that reduction of primary risk factors, especially smoking and high serum cholesterol, is important even after coronary heart disease has become manifest.

The results of prophylactic examination of a district population were compared with medical documents. Information on 85.7% of patients with CHD, 70.5% with arterial hypertension, 80.3% with chronic bronchitis and 83.3% with diabetes mellitus detected during the examination was absent in the medical documents. Prophylactic examination of the population, education of a district physician in methods of primary and secondary prophylaxis of chronic incommunicable diseases, the availability of health educational literature brought about an increase in the volume of therapeutic, diagnostic and preventive activities in this district, however they did not have great influence on the prevalence of risk factors in the population over a 2-year period.
