title: [10-year survival after myocardial infarction. Longitudinal study of a hospital population].
abstract: In this study, 321 patients discharged from hospital after an acute myocardial infarction were followed for 10 years or until death. Death rate was 46.4% and 30.8% of all fatalities was sudden. In over 80% of the cases death was from cardiac causes and frequently occurred out of hospital. Univariate analysis showed that age, female sex, previous infarction, diabetes, heart failure during hospitalization, heart murmur, NYHA class III or IV, post-infarction angina, intraventricular conduction defects, cardiomegaly, ST displacement, were all associated with an increased death rate. A positive exercise test 6-17 months after infarction, was associated with a 4-fold mortality increase. Bypass played a minor role in this series since only 6.8% of the patients underwent this operation. A nonfatal infarction recurred in 71 patients (22.1%) with an annual rate of 2.2%. Annual death rate after the first 2 years of follow-up was 3.9%, as in most recent reports on survival after myocardial infarction.
