Abstract

The purpose of this study was to determine the long-term prognosis of patients with an isolated total occlusion of the left anterior descending artery (LAD). A total of 173 male patients with a chronic LAD occlusion and <50% narrowing of the other coronary arteries (group I) was compared with a group of 177 male patients with only insignificant coronary artery disease and a normal left ventricular function (group II). Baseline characteristics of both groups were comparable except for the inclusion of 54 patients (31.2%) with moderately or markedly reduced left ventricular systolic function in group I. During an 8-year follow-up period there was a greater number of patients with cardiac events in group I when compared with group II: cardiac death 11.2% versus 0.6% (p < 0.0001), myocardial infarction 12.7% versus 3.4% (p = 0.0001), myocardial revascularization procedures 11.6% versus 3.4% (p = 0.04). Stepwise discriminant analysis showed that a reduced ejection fraction and a family history of coronary artery disease were the best predictors for these adverse cardiac events.
