aactive smoking was evaluated at the time of admission to the hospital (day 0 of AMI). Other patients were non-smokers (patients who had never smoked) or former smokers (patients who had stopped smoking at least three months before study); bChi-2 test, t-test. LVEF, left ventricular ejection fraction; NS, not significant; SD, standard deviation.
