title: Risk factors for pre, intra, and postoperative hospital mortality in patients undergoing aortic surgery.
abstract: OBJECTIVE
  The primary objective was to identify predictors of hospital mortality in patients undergoing aortic surgery. The secondary objective was to identify factors associated with clinical outcome composed hospital (death, bleeding, neurologic complications or ventricular dysfunction).
  
  
  METHODS
  A cross-sectional design with longitudinal component. Through chart review, 257 patients were included. Inclusion criteria were: aortic dissection Stanford type A and ascending aortic aneurysm. Exclusion criteria were acute aortic dissection, of any kind, and no aortic aneurysm involving the ascending segment. Variables assessed: demographics, preoperative factors, intraoperative and postoperative.
  
  
  RESULTS
  Variables with increased risk of hospital mortality (OR, 95% CI, P value): black ethnicity (6.8, 1.54-30.2; 0.04), cerebrovascular disease (10.5, 1.12-98.7; 0.04), hemopericardium (35.1, 3.73-330.2; 0.002), Cabrol operation (9.9, 1.47-66.36; 0.019), CABG simultaneous (4.4; 1.31 to 15.06; 0.017), bleeding (5.72, 1.29-25.29; 0.021) and cardiopulmonary bypass (CPB) time [min] (1.016; 1.0071.026; 0.001). Thoracic pain was associated with reduced risk of hospital death (0.27, 0.08-0.94, 0.04). Variables with increased risk of hospital clinical outcome compound were: use of antifibrinolytic (3.2, 1.65-6.27; 0.0006), renal complications (7.4, 1.52-36.0; 0.013), pulmonary complications (3.7, 1.58.8, 0.004), EuroScore (1.23; 1.08-1.41; 0.003) and CPB time [min] (1.01; 1.00 to 1.02; 0.027).
  
  
  CONCLUSIONS
  Ethnicity black, cerebrovascular disease, hemopericardium, Cabrol operation, CABG simultaneous, hemostasis review and CPB time was associated with increased risk of hospital death. Chest pain was associated with reduced risk of hospital death. Use of antifibrinolytic, renal complications, pulmonary complications, EuroScore and CPB time were associated with clinical outcome hospital compound.
