Objectives: To identify the variables related to morbidity and risk factors for death of patients that undergo to urgent myocardial revascularization surgery. Method: Historical cross sectional study. It included 232 patients aged ≥18 years old that underwent to isolated myocardial revascularization surgery, with or without cardiopulmonary bypass. Those surgeries were urgents and were adopted as emergency measures. It happened from January 1996 to December 2014. The total of revascularization myocardial surgeries carried out in this period were 3772 Results: The frequency of death observed in this sample was 117 (50.4%). Multivariate analysis identified as risk predictors: age ≥65 years old (OR: 2.34; 95% CI 1.35 to 5.27; P = 0.007), congestive heart failure class III and IV (OR: 2, 67, 95% CI 1.35 to 5.28; P = 0.005), cardiopulmonary bypass time> 90 minutes (OR: 2.52, 95% CI 1.21 to 4.17; P = 0.001), cardiogenic shock (OR: 3.47; 95% CI 1.70 to 7.07; P = 0.001), acute myocardial infarction (OR: 2.73, 95% CI 1.25 to 5.94, P = 0.011), bleeding (OR: 3.06, 95% CI 1.00 to 9.37; P = 0.049). Conclusion: Age, chronic obstructive pulmonary disease, class III and IV of congestive heart failure, cardiopulmonary bypass time, cardiogenic shock, acute myocardial infarction and bleeding they were independent predictors of in-hospital mortality in patients that undergo to myocardial revascularization surgery.
