[Results of 2-year study of morbidity of myocardial infarct (according to material of the myocardial infarction registry)].

The results of a two-year study conducted in accordance with the programme of the Myocardial Infarction Register in the Sokolniky district of Moscow with nearly 164,000 population are presented. The incidence of myocardial infarction in the 20-64 year age group comprises 2.87 and 3.08 among males and 1.52 and 1.44 among females, per 1,000 population for the 1st and 2nd years of the study respectively. The incidence of various clinical forms of myocardial infarction onset and of some complications developing in the acute phase of the disease was established. The typical variant of clinical manifestations is observed in 84.1% of the patients with the onset of myocardial infarction. The most frequently observed complication during the acute period of the disease (nearly in every 5th patient) is cardiac failure. Cardiogenic shock is observed only in 4.4-3.8% of the patients, aged under 64 years. Prior to the development of myocardial infarction 82.3% of the patients suffered angina pectoris, 55-62% arterial hypertension, 29-33% had survived another myocardial infarction earlier.
