[Results of the conservative treatment of patients with unstable stenocardia]

The results of conservative treatment were reviewed in 100 patients with unstable angina. In hospital, the condition was stabilized in 73% of patients, acute myocardial infarction developed in 24%, and fatal outcomes resulted in 7%. In the first year since the diagnosis of unstable angina was made, the incidence of acute myocardial infarction was 32%, with 14% mortality. Further prognosis for unstable angina was basically similar to that for chronic coronary heart disease. A clear-cut correlation was demonstrated between the frequency of anginal attacks, total ST displacement, the severity of coronary-bed and myocardial lesions and the incidence of acute myocardial infarction and death.
