title: [Risk Factor Analysis of Pneumonia after Cardiovascular Surgery].
abstract: Pneumonia is a major and life-threatening complication after cardiovascular surgery. The objective of our study was to describe epidemiology, clinical characteristics, and risk factors of pneumonia after cardiovascular surgery. From January 2007 to December 2011, 511 consecutive patients (age 67.3±11.9;336 men, 175 women) were enrolled in this study. Pneumonia was diagnosed according to Centers of Disease Control and Prevention surveillance criteria for healthcare associated infection. Data collection included preoperative, intraoperative, and post-operative variables. The overall incidence of pneumonia was 72 cases(14.0%). The mortality in pneumonia group was significantly higher than that in non-pneumonia group (16.6% vs 4.3%, Odds ratio 4.4 p<0.001). Multi-logistic analysis revealed that elderly patient, preoperative congestive heart failure, preoperative hemodialysis, and operation of the thoracic aorta were independent risk factors for pneumonia after cardiovascular surgery.
