[Role of heredity in the prevalence of ischemic heart disease and its risk factors].

The relationship of heredity with CHD prevalence and the main risk factors (RF) was analyzed on the basis of the results of a primary cardiological screening of the male population aged 40 to 59 in Minsk and Kaunas (10012 persons). The results of the analysis were in favor of hereditary predisposition to CHD. The prevalence of CHD and the main RF in probands with aggravated heredity was much higher than that in probands with favorable heredity. CHD prevalence in the compared groups was 12.4 and 10.7%; SK 3.9 and 0.2%; cerebral stroke 1.6 and 0.6%, respectively. Statistically significant changes were also revealed in RF frequency: AH--32.6 and 27.1%; HCS--27.7 and 24.1%; EBM--16.6 and 13.8%; smoking--43.6 and 47.0%. Over 1/3 of all types of CHD and AH were found in the persons with hereditary predisposition to CHD on the maternal side with a tendency to CS.
