Coronary artery bypass graft surgery versus percutaneous coronary intervention with drug-eluting stents for left main coronary artery disease: A meta-analysis of randomized trials

From the present updated meta-analysis of available studies on LM coronary disease treatment, there were no differences in mortality, myocardial infarction, and stroke rate at 3-5 years follow-up after CABG or PCI, but CABG decreased the rate of repeat revascularization and non-periprocedural infarction. However, at short-term follow-up, CABG showed higher rate of stroke and periprocedural myocardial infarction, but these effects attenuated over time. These findings merit further investigation at longer follow-up.
