Objective(s): To determine One-month survival after CABG in Shariati Hospital.
Methods: We followed 340 patients who underwent Isolated-CABG in Shariati Hospital and used survival analysis to compare common coronary risk factors and to assess surgical factors related to survival after CABG.
Results: Smoking was more prevalent in males than in females but prevalence of hypertension, diabetes and hperlipidemia was greater in women. Female subjects were older, had greater Body Mass Index (BMI) and left ventricular ejection fraction (LVEF) and had undergone more non-elective surgery compared to males. Most patients had received 3 or 4 grafts (range 1-6 grafts). There was no difference in aortic cross clamp and anesthesia time between the two genders. Females were hospitalized for longer periods after surgery and their mortality rates were greater. One-month survival ratio estimated by the Kaplan Meier method was   97.1% and 88.4% in males and females respectively. The overall survival rate was 95.3%.
Conclusion: The factors related to poor survival were: female gender, non-elective surgery, lengthy aortic cross clamp and anesthesia time and the history of: hypertension, hyperlipidemia, previous CABG and CCU hospitalization.
