Abstract：Objective To discuss the difference in immediate and long-term curative effects on coronary heart disease (CHD) between percutaneous coronary intervention (PCI) and off-pump coronary artery bypass grafting (OPCABG).Methods CHD patients (n=40) undergone PCI and CHD patients (n=40) undergone OPCABG were retrospectively analyzed in the Central Hospital of Zhengzhou City from Jan. 2014 to Jan. 2015. The status of tracheotomy, hemodialysis, sternal infection, postoperative atrial fibrillation and in-hospital mortality, and changes of left ventricular ejection fraction (LVEF) were compared, and incidence of major adverse cardiovascular events (MACE), re-hospitalization rate and mortality were recorded in 2 groups during 2-y follow-up period.Results The difference in tracheotomy, hemodialysis, sternal infection, postoperative atrial fibrillation and in-hospital mortality had no statistical significance between 2 groups (P>0.05). The rate of endotracheal re-intubation was higher in OPCABG group than that in PCI group [20.00％ (8/20)vs. 2.50％ (1/40),P<0.05]. The difference in LVEF had no statistical significance between 2 groups before the operation (P>0.05), and LVEF was improved in 2 groups after the operation (P<0.05). The difference in LVEF had no statistical significance between 2 groups after the operation (P<0.05). The results of 2-y follow-up showed that the difference in stroke, re-revascularization and mortality had no statistical significance between 2 groups (P<0.05). The rates of relapse myocardial infarction [2.63％ (1/40)vs. 18.92％ (7/40)], relapse angina pectoris [2.63％ (1/40)vs. 16.22％ (16/40)] and re-hospitalization [10.53％ (4/40)vs. 40.54％ (15/40)] were lower in OPCABG than those in PCI group (P<0.05).Conclusion The immediate and long-term mortality is similar in CHD patients undergone PCI or OPCABG, while long-term incidence of MACE is lower in CHD patients undergone OPCABG.
