Adverse Cardiovascular Outcomes associated with Coronary Artery Bypass Surgery and Percutaneous Coronary Intervention with Everolimus Eluting Stents: A Meta-Analysis.

This study aimed to compare the mid-term adverse cardiovascular outcomes associated with Coronary Artery Bypass Surgery (CABG) and Percutaneous Coronary Intervention (PCI) with Everolimus Eluting Stents (EES). Electronic databases were searched for studies comparing the mid-term (>1 year) adverse cardiovascular outcomes between CABG and PCI with EES. Odd Ratios (OR) with 95% Confidence Intervals (CIs) were calculated and the pooled analyses were performed with RevMan 5.3 software. A total number of 5207 patients were involved in this analysis. No significant difference was observed in mortality between CABG and EES with OR: 0.90, 95% CI: 0.73-1.10; P = 0.30. Moreover, CABG was associated with a high stroke rate, with OR: 0.73, 95% CI: 0.45-1.17; P = 0.19, without any statistical significant. CABG was associated with significantly lower Major Adverse Cardiac Events and Myocardial Infarction with OR: 1.46, 95% CI: 1.05-2.04; P = 0.03 and OR: 1.46, 95% CI: 1.01-2.12; P = 0.05 respectively whereas PCI was associated with a significantly higher repeated revascularization with OR: 2.21; 95% CI: 1.76-2.77; P = 0.00001. In conclusion, significant differences were noted in several subgroups analyzing the mid-term cardiovascular outcomes between CABG and EES.
