Background-Whether Coronary artery bypass grafting (CABG) confers a survival benefit in patients with diabetes mellitus(DM) and complex coronary artery disease (CAD), including left main CAD and multivessel coronary disease (MVD) after a follow up period ≥ 5 years remains unknown.
Methods- Electronic databases (PubMed, Embase, Scopus, Cochrane) were searched from inception to December 12th 2020. Using a generic invariance weighted random effects model, Hazard ratios (HRs) and their 95% confidence intervals (CIs) from individual studies were converted to Log HRs and corresponding standard errors, which were then pooled. The primary outcome of interest was all-cause mortality and major adverse cardiac and cerebrovascular events (MACCE) which was defined as a composite of death, myocardial reinfarction and stroke at ≥ 5 years.
Results-A total of 8 studies with 13336 participants(PCI = 6783, CABG = 6553)were included in our analysis. Mean age was 54.6 and 55.3 in the PCI-DES and CABG groups respectively. The 5-yr follow-up outcomes including all-cause mortality (HR 1.37; 95%CI 1.15-1.65; p = 0.0006, I2 = 0)and MACCE (HR 1.48; 95%CI 1.29-1.69; p < 0.00001, I2 = 0) were significantly higher with PCI as compared to CABG. Furthermore, at >5 year follow-up, all-cause mortality (HR 1.35; 95%CI 1.10-1.66; p = 0.004, I2 = 37) and MACCE (HR 1.98; 95%CI 1.85-2.12; p < 0.00001, I2 = 0) had similar outcomes.
Conclusion-Amongst patients with DM and Complex CAD ( left main/MVD), CABG was associated with improved long-term mortality and freedom from MACCEs as opposed to PCI-DES. CABG is the preferred revascularization strategy in patients with complex anatomic disease and concurrent diabetes.
