This meta-analysis was performed to compare two methods of superior revascularization strategies coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in patients with multivessel and/or left main coronary artery disease for elderly patients diabetes mellitus.


An electronic search of recent studies (2009–2019) was carried out using “diabetes mellitus”, “coronary artery bypass surgery”, and “percutaneous coronary intervention” as the main search terms. Stata software (version 15.0) was used to calculate relative risk (RR) and 95% confidence intervals (CIs). 


Among those observational studies, PCI and CABG patients did not differ significantly in their rates of stroke/cerebrovascular events(CVE)/cerebrovascular accident(CVA) (RR 0.98 95% CI 0.87-1.10;P=0.697 ) and cardiac death (RR 1.22 95% CI 0.95-1.57;P=0.118 ). However, rates of major adverse of cardiac and cerebral events(MACCEs), all-cause death, myocardial infraction(MI) and any repeat revascularization were significantly higher in the PCI group. Although there was no significant difference of MI (RR 1.26 95% CI 0.90-1.77;P=0.173) and stroke/CVE/CVA (RR 0.52 95% CI 0.26-1.03;P=0.061) among those RCT studies, the CABG significantly had lower all-cause death, cardiac death and any repeat revascularization.


Despite the high potential risk of stroke/CVE/CVA, CABG was better than PCI for diabetic elderly patients with multivessel and/or left main coronary artery disease  in clinical practice.
