The article compares the results of the screening of 3820 males aged 40 to 59 years, representative of the open population, and the mortality rate over a 6-year-follow-up. Mortality was the highest in males in whom angina pectoris was combined with "ischemic" codes on the ECG and the lowest in subjects without CHD symptoms and without codes of left ventricular hypertrophy. The study showed a fairly high prognostic value of the epidemiologic method of CHD diagnosis.
