Non-infarct-related artery revascularization during primary percutaneous coronary intervention for ST-segment elevation myocardial infarction: A systematic review and meta-analysis

There is paucity of randomized data to guide management of STEMI patients with multivessel disease. SS-PCI group in cohort studies has higher baseline risk compared to IRA-PCI. The primary end point is higher for SS-PCI in observational cohort studies but this difference did not persist after exclusion of shock patients and for analysis limited to randomized controlled trials. These findings underscore the need of a large randomized controlled trial to guide therapy for a commonly encountered clinical situation.
