Abstract

To substantiate the hypothesis that patients with antecedent angina(> or =24hr before myocardial infarcton) are more likely to have a significant residual stenosis than are those without antedecent angina, the coronary angiogram of 27 patients with successful coronary thrombolysis for acute myocardial infarction were reviewed. In comparison with the patients without antecedent angina the patient with antecedent angina had an increased mean stenosis (86.9% vs 69.3%) and had a more decreased ejection fraction(52.3% vs 65.6%). These findings suggest that angina pectoris before acute myocardial infarction would be regarded as one of high risk factors after acute myocardial infarction.
