- W2055461353 abstract "Patients with multivessel coronary artery disease and left ventricular dysfunction represent a high-risk subgroup in whom coronary artery bypass grafting has been shown to improve survival compared with that of medically treated patients. The comparative benefits and risks of coronary angioplasty and bypass surgery in this subgroup of patients are unclear. This study retrospectively analyzes 100 consecutive patients treated with bypass surgery compared with a matched, concurrent cohort of 100 treated with multivessel angioplasty. Early results favored angioplasty; a hospital stay of 12.8 days was noted in the bypass group compared with 4.3 days in the angioplasty group (p < 0.001). In-hospital mortality rates were similar in the bypass (5%) and angioplasty (3%) groups (p = NS). Stroke was observed significantly more often in the bypass group (7 vs 0%). However, late follow-up favored bypass patients; repeat revascularization procedures and late myocardial infarction occurred more frequently during follow-up in the angioplasty group. During 5-year follow-up, superior relief from disabling angina (99 vs 89%; p = 0.01) and a trend toward improved survival (76 vs 67%; p = 0.09) were observed in the bypass group as compared with the angioplasty group. Multivariate correlates of late mortality included age and incomplete revascularization, but not mode of revascularization. Thus, in patients with multivessel coronary artery disease and left ventricular dysfunction, early results favor angioplasty, whereas late follow-up favors bypass surgery. However, late survival was similar in both groups of patients who were completely revascularized." @default.
