BackgroundChronic kidney disease is an independent predictor of perioperative cardiovascular morbidity and mortality. We analysed the preoperative estimated glomerular filtration rate (eGFR) as a risk factor for perioperative major adverse cardiovascular and cerebrovascular events (MACCE) in non-cardiac surgery.MethodsIn a post hoc analysis of the ANESCARDIOCAT database, patients were classified into six stages of eGFR calculated with the abbreviated Modification of Diet in Renal Disease Study and the Chronic Kidney Disease Epidemiology Collaboration equations: >90 (1), 60-89.9 (2), 45-59.9 (3a), 30-44.9 (3b), 15-29.9 (4), and <15 (5) ml min(-1) 1.73 m(-2). We analysed differences in MACCE, length of hospital stay, and all-cause mortality between eGFR stages.ResultsThe eGFR was available in 2323 patients. Perioperative MACCE occurred in 4.5% of patients and cardiac-related mortality was 0.5%. Five hundred and forty-three (23.4%) patients had an eGFR of <60 ml min(-1) 1.73 m(-2) and 127 (5.4%) had an eGFR below 45 ml min(-1) 1.73 m(-2). Logistic regression analysis showed that MACCE increased with eGFR impairment (P<0.001), with a marked increase from stage 3b onwards (odds ratio 1.8 vs 3.9 in 3a and 3b, respectively, P=0.047). All-cause mortality was not related to eGFR (P=0.071), but increased substantially between stages 3b and 4. The length of stay correlated with eGFR (P<0.001).ConclusionsPerioperative MACCE increase with declining eGFR, primarily when <45 ml min(-1) 1.73 m(-2). We recommend the use of preoperative eGFR for cardiovascular risk assessment.© The Author 2014. Published by Oxford University Press on behalf of the British Journal of Anaesthesia.
