Methods A total of 3176 CAD patients confirmed by coronary angiography were included. OMT was defined as the combination of anti-platelet drugs, statins, beta blockers, and angiotensin converting enzyme inhibitors or angiotensin receptor blockers. Factors for OMT and its prognostic value were analyzed in CAD patients across different subgroups. Results Out of 3176 patients, only 39.8% （n = 1265） were on OMT at discharge. Factors associated with OMT at discharge were pre-admission OMT and discharge department. All-cause mortality occurred in 6.8% （n = 217） of patients. Multivariate analyses indicated that OMT was significantly associated with reduced all-cause mortality （HR： 0.65, 95% CI： 0.45~0.95; P = 0.025）. Sub-group analyses indicate that male acute coronary syndrome （ACS） patients were more likely to receive survival benefits with OMT at discharge. The positive impact of OMT at discharge was more apparent after 24 months, regardless of revascularization therapy. Four-drug combination of OMT was superior to 3-drug combination therapy in ACS patients but not in stable patients. Conclusions OMT was asso- ciated with significant improvement in survival in patients with CAD. The positive impact of OMT was distinct in the CAD patients with different characteristics.展开更多
