Is chronic kidney disease predictive of coronary artery bypass grafting after acute coronary syndrome? A systematic review and meta-analysis

Abstract Background Coronary artery bypass grafting (CABG) provides superior long-term outcomes to percutaneous coronary intervention (PCI) for multi-vessel coronary artery disease. People with chronic kidney disease (CKD) are at increased risk of multi-vessel coronary artery disease, and experience greater morbidity and mortality following acute coronary syndrome (ACS). Purpose To determine whether CKD affects choice of revascularisation strategy after ACS. Methods We searched EMBASE, MEDLINE, SCOPUS, CENTRAL and the NIHR’s website of funded studies to identify articles referring to ACS and invasive coronary management in high-income countries over the past 12 years until 29th September 2023. Full text articles were included if data on rates of CABG were reported in people with and without CKD who were revascularised following ACS. CKD was defined as one or more recording of an estimated glomerular filtration rate (eGFR)
