Angina pectoris and myocardial infarction.
Angina pectoris was studied in a representative series of male patients (n = 504) with a first myocardial infarction (MI) surviving the hospital stay. The prevalence of questionnaire angina before MI was 28% and of effort-induced chest pain alone 40%. Of the patients with effort-induced chest pain, 72% retained symptoms also after MI. No correlation with age was found. Three months after and one year after infarction the prevalence of effort-induced chest pain was 55% and 45%, respectively. The patients with effort-induced chest pain before MI had a somewhat more severe clinical course and a significantly higher death rate (15% versus 6%) than those without chest pain.
