['Both preoperative left ventricular dysfunction (LVD) and acute kidney injury (AKI) in the postoperative period are independently associated with mortality. We evaluated the prevalence and prognostic implications of AKI in a cohort of vascular surgery patients.', 'Before vascular surgery, 1,158 patients were screened for LVD. Development of AKI, defined by RIFLE classification, was detected by serial serum creatinine measurements at days 1 to 3 after surgery. Primary end point was cardiovascular mortality during a median follow-up of 2.2 years (interquartile range [IQR] 1.0-4.0).', 'LVD was present in 558 patients (48%), and 120 patients (10%) developed postoperative AKI. Subjects with LVD developed postoperative AKI more often than patients without LVD (8% vs. 13%, p=0.01). Patients were categorized as (i) no LVD, without AKI (n=551, 48%), (ii) LVD without AKI (n=487, 42%), (iii) no LVD, with AKI (n=49, 4%) and (iv) LVD with AKI (n=71/6%). Patients with LVD prior to surgery who developed postoperative AKI had the highest cardiovascular mortality risk (hazard ratio = 4.9; 95% confidence interval, 2.9-8.2).'] Does preoperative left ventricular dysfunction predispose to postoperative acute kidney injury and long-term mortality?
