[Assessment of early mortality risk factors undergoing coronary artery bypass graft surgery]

To analyze early mortality risk factors and clinical characteristics in our patients undergoing coronary artery bypass graft (CABG) surgery.

Clinical data of 310 consecutive patients undergoing CABG from January 2005 to March 2007 were collected. Twenty-two risk factors were evaluated by univariate and multivariate Logistic stepwise regression analysis.

Univariate statistical analysis revealed that factors significantly correlated with early death were 12 variables including age, diabetes, neurological dysfunction, old myocardial infarction, acute myocardial infarction, ejection function, left main artery stenosis, emergency procedure, cardiopulmonary bypass time, aortic cross-calming time, and mechanical ventilation time. Logistic stepwise regression analysis showed that emergency procedure, ejection function, age, cardiopulmonary bypass time, and mechanical ventilation time were independent risk factor of early mortality after procedure.

Emergency procedure, ejection function, age, cardiopulmonary bypass time, and mechanical ventilation time are independent risk factors of early mortality after CABG procedure.
