The present study examined whether preoperative insulin resistance or adiponectin were associated with short- and long-term adverse outcomes in non-diabetic patients undergoing elective cardiac surgery. Methods In a prospective study we assessed insulin resistance and adiponectin levels from preoperative fasting blood samples in 836 patients undergoing cardiac surgery. Population-based medical registries were used for postoperative follow-up. Outcomes included all-cause death myocardial infarction or percutaneous coronary intervention stroke re-exploration renal failure and infections. The ability of insulin resistance and adiponectin to predict clinical adverse outcomes was examined using receiver operating characteristics. Results Neither insulin resistance nor adiponectin were statistically significantly associated with 30-day mortality but adiponectin was associated with an increased 31-365-day mortality adjusted odds ratio 2.9 95 confidence interval 1.3-6.4 comparing the upper quartile with the three lower quartiles. Insulin resistance was a poor predictor of adverse outcomes. In contrast the predictive accuracy of adiponectin area under curve 0.75 95 confidence interval 0.65-0.85 was similar to that of the EuroSCORE area under curve 0.75 95 confidence interval 0.67-0.83 and a model including adiponectin and the EuroSCORE had an area under curve of 0.78 95 confidence interval 0.68-0.88 .
