Abstract:
Objective:To investigate the impact of previous coronary artery bypass grafting(CABG) on long-term outcomes in patients undergoing percutaneous coronary intervention(PCI).
Methods:A total of 10 724 consecutive coronary heart disease patients undergoing PCI between January and December 2013 in Fuwai hospital were prospectively included in this research. According to CABG history, the patients were divided into CABG group(437 cases) and without CABG group(10 287 cases). The patients were followed up for 2 years. Major adverse cardiovascular and cerebrovascular events(MACCE) including death, myocardial infarction, revascularization and stroke, and in-stent thrombosis following PCI were compared between the 2 groups. Multivariate Cox regression analysis was used to identify independent risk factors of poor prognosis.
Results:Compared with without CABG group, CABG group were older((61±10)years vs.(58±10)years, P<0.001), and more often had diabetes(35.7%(156/437) vs. 30.0%(3 082/10 287), P=0.012), hyperlipoidemia(73.9%(323/437) vs. 67.0%(6 888/10 287), P=0.003), previous myocardial infarction(31.1%(136/437) vs. 18.7%(1 925/10 287), P<0.001), PCI history(61.6%(269/437) vs. 23.0%(2 371/10 287), P<0.001), and cerebrovascular disease(7.1%(31/437) vs. 10.9%(1 119/10 287), P=0.013). After 2 years follow-up, rates of cardiac death(1.8%(8/437) vs. 0.6%(66/10 287), P=0.010), revascularization(11.2%(49/437) vs. 8.5%(877/10 287), P=0.049) and MACCE(15.1%(66/437) vs. 12.0%(1 231/10 287), P=0.049) were significantly higher in CABG patients than in without CABG group. There were no significant difference in all cause death(2.1%(9/437) vs. 1.2%(122/10 287), P=0.114), recurrence of myocardial infarction(2.3%(10/437) vs. 2.0%(204/10 287), P=0.600), stroke(1.1%(5/437) vs. 1.4%(140/10 287), P=0.701), and in-stent thrombosis(1.1%(5/437) vs. 0.6%(61/10 287), P=0.194). Multivariate Cox regression analysis showed that previous CABG was an independent risk factor of cardiac death(HR=2.13, 95%CI 1.02-4.46, P=0.045)and revascularization(HR=1.35, 95%CI 1.01-1.81, P=0.040). However, after propensity score matched analyses(429 pairs), previous CABG was no longer an independent risk factor of cardiac mortality (HR=0.97, 95% CI 0.37-2.54, P=0.954)and revascularization(HR=1.74, 95%CI 0.94-3.21, P=0.753).
Conclusion:Previous CABG is not an independent risk factor of poor prognosis in coronary heart disease patients undergoing PCI.
