519 patients with angina pectoris studied by selective coronary arteriography and left ventriculogram, were followed for a period ranging from 18 months to 7 years. The mean follow-up was 42.2 months. The patients showed a survival probability of 81% at the 7th year. After 5 years the survival probability was 83.2% for patients with typical stable angina, 70.3% for patients with unstable angina, 96.7% for patients with atypical angina. The survival probability was 78.8% for the male sex and 94.6% for the female (at the 5th year). Age, a long-lasting angina, the presence of: previous infarction, myocardial failure, cigarette smoking, hyperlipidemia, cardiomegaly and an ischemic resting EKG were factors with poor prognostic value. The prognostic value of significant coronary stenosis was confirmed. The survival probability at the 5th year of the patients without critical stenosis was 96.6%, of patients with stenosis of 1, 2 and 3 main coronary arteries was respectively: 87.6%, 79% 54.7%. Significative prognostic differences were observed in patients with normal left ventricle kinesia (survival probability at the 5th year: 90%), compared with patients with severe VS ipokinesia (62.7%) and with VS diskinesia (69%). In the follow-up period an incidence of 9% of myocardial infarctions was observed. The degree of each stenosis and the number of vessels involved, the type of angina, the presence of risk factors or previous myocardial infarction did not affect the clinical evolution of angina.
