Factors affecting the 5 year survival rate of men following acute coronary heart disease

Abstract

A total of 213 male patients who survived an initial episode of acute coronary inusfficiency or myocardial infarction for 28 days have been followed for 5 years. The effect of age, weight, severity of infarction diastolic blood pressure, serum cholesterol, and cigarette smoking at the time of the initial attack on postinfarction morbidity and death was examined. Only severity of infarction adversely influenced the long-term mortality rate; none of the factors studied was related to subsequent morbidity. The effect of subsequent cigarette smoking on morbidity and death was noted over the 5 year period. Smoking did not affect subsequent morbidity but there was an increased death rate among those who continued to smoke. This effect of smoking was independent of the severity of infarction. Improved long-term survival may be predicted for patients who stop or markedly reduce cigarette smoking.
