Abstract
- Background. Improved understanding of the incidence and risk factors for operative complications and longterm mortality following coronary artery bypass grafting (CABG) is needed to better define the optimal role for CABG in patients with chronic kidney disease (CKD). Methods. We analysed 2438 patients who underwent CABG at a single centre between 2005 and 2008. Multivariable regression was used to analyse associations and to generate a CKD-specific predictive tool. Results. Operative mortality was 4.8% in individuals with stage 3 CKD, 7.1% in individuals with stage 4–5 CKD and 2.2% in those without significant CKD (P< 0.001). CKD was associated with post-operative blood transfusion, acute kidney injury, myocardial injury and cardiac arrest, and use of exogenous blood and acute kidney injury were strongly associated with in-hospital death in CKD patients. Patients with stage 3 (HR 1.64, 95% CI 1.30–45.94) and stage 4–5 CKD (HR 2.77, 95% CI 1.00–2.68) were more likely to die during follow-up than those without CKD, but mortality rates were low among patients who survived to discharge—stage 3 (0.006 deaths/year) and stage 4–5 CKD (0.009/year). A scoring system including urgent or emergent surgery (OR 2.30), prior cardiac surgery (OR 3.06), concurrent valve surgery (OR 2.06), preoperative shock (OR 6.18), and prior stroke (OR 1.98) had 96.4% percent specificity for the detection of in-hospital death in patients with CKD. Conclusions. Perioperative mortality and morbidity remain more frequent in patients with stage 3–5 CKD than patients with preserved renal function, but long-term outcomes in patients surviving hospitalization are favourable. We have developed a predictive tool that holds promise as a means of identifying CKD patients most likely to survive surgery and benefit from CABG.
