Effects of a multifactorial prevention trial of coronary heart disease on the seasonal variation of the incidence of major cardiovascular events.

Under the influence of a primary prevention trial of coronary heart disease carried out for 10 years (1971-1982) in male subjects aged 40 to 60 years at entry, the curves of the seasonal variation of the incidence of myocardial infarction, sudden death and stroke were changed. The most important reductions of the incidence of these events were registered in spring and in September. In the rest of the year the effect of the action becomes variable according to the month and to the particular major events.

Transmission filter for the compensation of the intensity falloff in the image plane by using opaque dots.

A special type of transmission filter (dotted filter) for compensating the intensity falloff in the image plane is described.A dvantages and disadvantages area lso discussed.

Seasonal variations of serum cholesterol detected in the Bucharest Multifactorial Prevention Trial of Coronary Heart Disease. Ten years follow-up (1971-1982).

A group of 4800 men, aged fourty to sixty at entry, subjected to a multifactorial prevention trial of coronary heart disease for a ten-year period, showed spontaneous seasonal variations of serum cholesterol, characterized by increases in winter and decreases in summer. The authors discuss the relationship between the food changes and the seasonal variation of serum cholesterol values.

Ischemic heart disease in relation with the type of behavior and the emotional state.

The relationship between the cardiovascular state, on the one hand, and the type of behavior and emotional state on the other, was investigated in a professional type community of 550 subjects (280 men and 270 women) ranging in age from 20 to 64 years. The subjects were submitted to medical examination (clinical, electrocardiographic and biochemical) for the detection of ischemic heart disease and its risk factors (arterial hypertension, smoking, over weight, hypercholesterolemia) and concomitantly to a psychologic examination consisting of anxiety test as a state and as a trait, multiple affectivity test and the test of self-rating behavioral type, for the study of the emotional state and the type of behavior. The relation between the results of the two examinations showed that ischemic heart disease (irrespective of the form) and its risk factors are associated to various extents and in different manners to the psychologic factors.

The evolution of atherosclerotic risk factors in a primary prophylactic survey. Ten-year longitudinal epidemiologic study (1971-1982).

The present work is a study of the evolution of atherosclerotic risk factors in the course of ten years, in a group of 5,000 male subjects, aged 40 to 60 years, from an urban district, undergoing a programme of primary prevention against ischemic heart diseases. The general intervention methodology and the results after five years follow-up were published in earlier papers. The present work describes the ten year evolution of the prevalence of the main atherogenic risk factors studied, the yearly rate of prevalences, first appearance and correction potency of the risk factors detected.
