Short- and long-term prognosis of off-pump coronary endarterectomy / 中华胸心血管外科杂志

ABSTRACT

Objective:To evaluate the prognosis of off-pump coronary artery bypass grafting combined(OPCABG) with coronary endarterectomy(CE) treating the diffuse coronary artery disease.Methods:From January 2012 to December 2014, the clinical data of 2 496 OPCABG patients in our department were retrospectively analyzed, and they were divided into OPCABG group and OPCABG+ CE group. After 1∶1 matching via the propensity score matching method, the perioperative prognosis, long-term survival and adverse cardiovascular and cerebrovascular events(MACCE) were compared between the two groups.Results:A total of 238 pairs of patients were included after propensity score matching. The incidence of postoperative AMI in the OPCABG+ CE group was significantly higher than that in the OPCABG group(5.04% vs. 1.68%, P=0.042). With an average follow-up of 7.3 years, there was no significant difference in the cumulative survival rate(92.44% vs. 88.65%, P=0.159) and long-term MACCE(10.92% vs. 15.13%, P=0.173) between the two groups. Compared with the OPCABG group, the recurrence of angina pectoris(CCS grade Ⅲ-Ⅳ) in the OPCABG+ CE group increased significantly(20.16% vs. 12.60%, P=0.026). Conclusion:The risk of early AMI and long-term angina recurrence after OPCABG+ CE is significantly increased, but the long-term survival and MACCE of OPCABG+ CE and OPCABG are comparable.
