The purpose of this study was to evaluate the outcome of percutaneous coronary intervention (PCI), coronary artery bypass graft surgery (CABG) and medical therapy in stable angina pectoris patients.
This is a multicenter, retrospective trial to assess the outcome of the PCI, CABG and medical therapy in patients who had stable angina pectoris between January 2003 and December 2011.
Among 8,770 CAD patients, 469 had stable angina pectoris and were managed by PCI (n=225), CABG (n =80) and medical therapy (n =164). The primary outcome measure is major adverse cardiac and cerebrovascular events (MACCE: all-cause mortality, myocardial infarction, stroke or re-revascularization).
The rate of all-cause mortality of PCI, CABG and medical therapy were 2.67%, 5.00% and 1.22% respectively, P=0.2263; The rates of MACCE were 11.6%, 7.5% and 8.5% respectively, P=0.4559.
Multivariable logistic regression analysis showed that compared with medical therapy, the hazard rates of MACCE of PCI and CABG were 0.879(PCI：OR=0.879, 95% CI 0.376-2.055, P=0.7898) and o.596 (OR=0.596, 95% CI, 0.143-2.484 P=0.5186), respectively. However, there was no statistical significance of the hazard rates of MACCE.
There was no difference in MACCE of stable angina pectoris patients by PCI, CABG and medical therapy.
