title: Prognosis after a first Q-wave myocardial infarction in ethnic Chinese people: a prospective study.
abstract: The prognosis after a first Q-wave myocardial infarction was investigated in 206 Chinese patients of 65 years or younger who had a predischarge cardiac catheterization and coronary angiography. Three patients studied were lost to follow-up. In the remaining 203 patients with ages of between 28 and 65 years, 101 (49.8%) had 0- or 1-vessel disease, 56 (27.6%) had 2-, and 38 (18.7%) had 3-vessel disease. Significant left main coronary artery stenosis was noted in 8 (3.9%). During a mean follow-up of 33 months, 33 (16.3%) patients had 36 episodes of cardiac events, and 16 (7.9%) died of cardiac causes. Stepwise logistic regression analysis revealed that the left ventricular ejection fraction and left main coronary artery disease were predictors of cardiac mortality, while age and the extent of coronary artery disease were predictors of total cardiac events. There was no variable that could predict recurrence of myocardial infarction.
