    Background And ObjetiveObesity is a disease that affects a large part of the population and has been associated with worse outcomes after cardiac surgery. The aim of our study is to evaluate the consequences of obesity related to postoperative complications, hospital length of stay and mortality.MethodsObservational, prospective, multicenter study of patients included in ARIAM registry of adult cardiac surgery between March 2008 to March 2011. We analyzed clinical variables, the surgical procedure, postoperative complications and mortality, comparing the group of patients with body mass index (BMI) greater or less than 30 kg/m(2).ResultsThe study included 4,172 patients with a mean age of 64.03 (SD 12.08) years, BMI 28.53 (4.7) and EuroSCORE 5.58 (2.91). In 1,490 patients (35.7%) BMI was greater than 30. There were no differences in the development of overall postoperative complications (33% in obese and non-obese 35.8%, P=.07), although there were less appreciated reoperation rate or stroke (P<.05), as well as further development postoperative renal failure (P=.009). After adjusting for severity and length of cardio by pass time, obese patients had lower mortality without being statistically significant. OR 0.94 (0.79-1.04). There were no differences in ICU length of stay, but obese patients had greater Ward length of stay 9.04 (10.43) vs. 8.18 (9.2) days, P=.01.ConclusionsObese patients undergoing cardiac surgery have a mortality, rate of complications and length of stay similar to non-obese. Obese patients required less reoperations but developed more frequently postoperative renal failure.Copyright © 2012 Elsevier España, S.L. All rights reserved.
