title: Prognosis in survivors of acute myocardial infarction occurring at age 70 years or older.
abstract: To identify prognostic factors in elderly persons who have survived acute myocardial infarction, 113 patients, aged 70 to 91 years (median 76), were followed for an average of 122 months (range 94 to 170). Eighty-four patients died, 61 (73%) from coronary artery disease. Overall mortality rates were 20.4% at 1 year, 30.1% at 2 years, 31.9% at 3 years, 45.1% at 4 years, 51.3% at 5 years and 69% at 10 years. Almost half (44%) of all deaths from coronary causes occurred in the first 2 years. Univariate analysis of 21 historical and clinical variables found several of prognostic significance: age, prior myocardial infarction, previous diastolic hypertension, history of diabetes mellitus, history of heart failure, presence of rales above the scapula, ventricular gallop, Killip class, cardiomegaly on admission chest x-ray and prescribing digitalis or diuretic at discharge. When these prognostic factors were entered into multivariate analysis, only Killip class (p less than 0.001) emerged as an independent predictor of survival.
