Postoperative rise in serum creatinine following coronary artery bypass grafting: how is this best measured and what is its significance? Mannacio et al.s paper provides a valuable contribution to the evidence base concerning multiple composite grafts, highlighting concerns regarding an inability to meet flow requirements during perioperative stress-testing [1]. Of particular interest was the authors' definition of preoperative renal dysfunction, and the cutoff level used for the postoperative rise in serum creatinine. The link between end-stage renal failure and predisposition to adverse outcomes following coronary artery bypass surgery is established [2]. More recently, researchers have considered the impact of lesser degrees of renal impairment on mortality following coronary artery bypass graft (CABG) [3], and previous definitions of acute renal failure have been challenged [4]. …
