A seven-year prospective study of a random 10% sample of a population of 50- to 59-year-old males from one municipal district in Moscow is reported. Mortality was reviewed among patients with complicated angina pectoris, i.e. those exhibiting other coronary symptoms as well, and among patients with uncomplicated angina as the primary and only sign of coronary heart disease (CHD). At long-term follow-up, the diagnosis of both varieties of angina is associated with aggravated vital prognosis. Some correlations between CHD risk factors and mortality are presented for both groups of anginal patients.
