Abstract: Abstract Objective：The study was performed to discuss the selection of different revascularization treatment in patients with coronary artery disease and type 2 diabetes. Methods：Four hundred and fifty-six patients with coronary artery disease and type 2 diabetes were divided into percutaneous coronary intervention（PCI）（n=288）and coronary artery bypass grafting（CABG）（n=168）group. The primary endpoints were major adverse cardiac events（MACE, including all-cause deaths, myocardial infarction，stroke）within 12 months，and the second endpoint was target vessel revascularization within 12 months. Results：The rate of myocardial re-infarction in PCI group was higher than CABG group（P=0.014）within 12 months. There were no significant differences between two groups in total adverse cardiac events（P=0.072）and other MACE（all P>0.05）,also in target vessel revascularization（P=0.727）within 12 months. High-SYNTAX subgroup of PCI group had more incidence of adverse cardiac events than high-subgroup of CABG（P=0.017）,while there is no difference in low-subgroup and middle-one（all P>0.05）. Conclusions：It could not come to the conclusion that CABG was much better than PCI in patients with coronary artery disease and type 2 diabetes, but it might have lower incidence of adverse cardiac events in High-SYNTAX subgroup which patients accept CABG.
