Major adverse cardiovascular events in patients undergoing percutaneous coronary intervention or coronary artery bypass graft with underlying chronic kidney disease

OBJECTIVE To assess early and late outcome in severe chronic kidney disease patients undergoing revascularisation. METHODS The retrospective ambi-directional cohort study was conducted at Tabba Heart Institute, Karachi, and comprised data from May, 2012, to July,2016, related to severe chronic kidney disease patients with creatinine clearance 0.05). Predictors of in-hospital adverse events were coronary artery bypass graft and cardiogenic shock (p<0.05). Follow-up was available in 181(94.3%) patients with a mean duration of 22.0±13.9 months. Heart failure and post-procedure stroke were independent predictors of late outcome (p<0.05). CONCLUSIONS Among patients with severe chronic kidney disease or end stage renal disease undergoing revascularisation, percutaneous coronary intervention PCI was performed in patients with less complex anatomy or as emergency for acute ST-elevation myocardial infarction. Coronary artery bypass graft patients had higher early mortality, but improved late survival.
