Revascularization of coronary artery disease in patients with left ventricular ejection fraction ≤40 % / 中国综合临床

ABSTRACT

Objective To investigate the effect of PCI/CABG for the patients with coronary artery disease(CAD) with LVEF≤40%. Methods 196 CAD patients with LVEF≤40% were divided into PCI (n = 106) and CABG group (n=90). The clinical factors, revaseularization, medication, and in-hospital and follow-up malignant cardiological events(MACCE) were retrospectively compared,and the survival curve were drew by COX regression.Results Survival rate of the PCI group and CABG group in 30-day (96% vs. 94% ), 1-year(95 % vs. 92% ), and 2-year(93% vs. 87% )were similar. There was no MACCE within 30 days in the two groups(92% vs. 92% ) and 1-year survival rate without MACCE was similar in the two groups(86% vs. 88% ). CABG group had higher 2- year survival rate without MACCE than PCI group (83%vs. 72% ). But the COX survival curves of the two group were not signifi-cantly different (P=0. 662). Conclusion The patients with LVEF ≤ 40% undergoing PCI have short-term and long-term survival rate similar to those accepting CABG.
