Six risk factors adversely affected long-term prognosis after acute myocardial infarction, with approximately half of 5-year survivors experiencing angina and two-thirds under 60 returning to work.
Cohort
The factors adversely affecting long-term prognosis differed from those affecting outcome of acute infarction. Individual factors were previous history of infarction or hypertension, tachycardia, cardiac arrest, ventricular arrhythmia, atrial fibrillation, 3rd heart sound, raised venous pressure, and pulmonary crepitations. Multivariate analysis reduced these to 6--previous infarct or hypertension, sinus tachycardia, cardiac arrest, ventricular arrhythmia, and artial fibrillation. Of those who survived 5 years, approximately half had angina. Two-thirds of the under 60 survivors were at their normal work.
