Safety and efficacy of percutaneous coronary intervention versus coronary artery bypass graft in patients with STEMI and unprotected left main stem disease: A systematic review & meta-analysis.

Introduction: Owing to its large area of supply, left main coronary artery disease (LMCAD) has the highest mortality rate among coronary artery lesions, resulting in debate about its optimal revascularization technique. This -analysis compares percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG) for the treatment of LMCAD.

Method: MEDLINE, TRIP, and Cochrane Central databases were queried from their inception until 25 April 2021, to determine MACCE (major adverse cardiac and cardiovascular events), all-cause mortality, repeat revascularization, myocardial infarction (MI) and stroke rates post-revascularization for different follow-ups.
