Abstract

Background. Severe coronary artery disease in patients with a markedly depressed left ventricular function is associated with a poor prognosis. Even though coronary angioplasty (PTCA) has been offered as an alternative to bypass surgery, the role of PTCA in the treatment of patients with severe left ventricular dysfunction has not been well defined. The aim of the present study was to evaluate the immediate and long-term results in patients with severe left ventricular dysfunction ≤35% who underwent PTCA. Methods. One hundred and twenty-five patients with a left ventricular ejection fraction ≤35% who underwent PTCA were analyzed. Results. The mean left ventricular ejection fraction was 29.7%. Eighty-seven patients (69.6%) had multivessel disease and 41 (32.8%) had previous coronary artery bypass graft. Intra-aortic balloon pumping was used in 12% of cases. Angiographic success was achieved in 96% of patients. Complete revascularization was achieved in 56 patients (44.8%). Major complications occurred in 4% of the population and 2 patients died (1.6 %). During the long-term follow-up re-PTCA due to angiographic restenosis was performed in 41 patients (34%); 12 patients (10.4%) died. The only parameter which significantly correlated with death was the presence of an occluded left anterior descending coronary artery not recanalized neither with PTCA nor with coronary artery bypass graft. Conclusions. These data suggest that PTCA may be an effective treatment for coronary artery disease in patients with left ventricular dysfunction and is associated with high procedural success rate and low complications; however, the long-term follow-up seems not to be influenced by the PTCA procedure.
