The Rate and Predictors of Mortality in Patients undergoing Coronary Artery Bypass Graft Surgery in Dr Heshmat Hospital 2011-2014

Introduction & Coronary artery bypass graft surgery is the most effective strategy in selected patients with coronary artery disease that improves clinical outcomes. Due to increasing trend toward this intervention, determining the risk factors and rate of operative mortality among these patients seem vital.
This descriptive study was conducted at Dr Heshmat Hospital from 2011 to 2014.By using the SPSS statistical software and Chi square, mann whitney , Fisher and logistic regression tests data were analyzed and risk factors for post coronary artery bypass grafting surgery mortality were evaluated.
Data from 2295 patients were collected. The operative mortality rate was 1.5%. Patient age, serum creatinine, valvular disease, prolonged intensive care unit duration, cardiopulmonary bypass time, had the strongest association with mortality (P=0.0001).
Our mortality rate was comparable to that reported in other countries. Identification of these factors in the perioperative setting may enhance resource utilization and improve mortality following cardiac surgery.
