Abstract
INTRODUCTION
In this meta-analysis, we aimed to systematically compare the 10-year outcomes of percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG) in patients with type 2 diabetes mellitus (T2DM) suffering from left main coronary artery disease (LMCD).
METHODS
Medical Literature Analysis and Retrieval System Online (MEDLINE), http://www.ClinicalTrials.gov , Excerpta Medica dataBASE (EMBASE), Cochrane Central, Web of Science, and Google scholar were searched for publications comparing 10-year outcomes of PCI versus CABG in patients with T2DM suffering from LMCD. Cardiovascular outcomes were considered as the clinical endpoints. Statistical analysis was carried out using RevMan software (version 5.4). Risk ratios (RR) with 95% confidence intervals (CI) were used to represent the data after analysis.
RESULTS
Eight studies (three randomized trials and five observational studies) with a total number of 3835 participants with T2DM were included in this analysis; 2340 participants were assigned to the PCI group and 1495 participants were assigned to the CABG group. Results of this analysis showed that mortality (RR 0.85, 95% CI 0.73-1.00; P = 0.05), myocardial infarction (RR 0.53, 95% CI 0.35-0.80; P = 0.002), repeated revascularization (RR 0.34, 95% CI 0.26-0.46; P = 0.00001), and target vessel revascularization (RR 0.26, 95% CI 0.18-0.38; P = 0.00001) were significantly higher with PCI when compared to CABG in these patients with diabetes and LMCD. Major adverse cardiac and cerebrovascular events were also significantly higher with PCI at 10 years (RR 0.67, 95% CI 0.49-0.92; P = 0.01). However, CABG was associated with a significantly higher risk of stroke (RR 2.16, 95% CI 1.39-3.37; P = 0.0007).
CONCLUSIONS
During a long-term follow-up time period of 10 years, PCI was associated with worse clinical outcomes compared to CABG in these patients with T2DM suffering from LMCD. However, a significantly higher risk of stroke was observed with CABG. This piece of information might be vital in order to carefully choose and prevent complications following revascularization in such patients.
