Background: It is known that women are considered under-privileged in cardiovascular medicine. There is no enough data about the effect of the gender on the clinical outcome following CABG surgery.

Methods: A retrospective study following 239 patients that underwent CABG surgery in the Baruch Padeh Medical Center in the last 4 years. There were 35 women and 204 men, aged 61.85±9.57 years. Gender was the independent variable and the dependent variables included the post-operative appearance of atrial fibrillation, mortality, re-admission rate, hospitalization time and the time that patients had to be connected to the cardio-pulmonary bypass machine (CPBM). We used logistic regression analysis to study the effect of WBCs on all the dependent variables.

Results: Women had a higher probability to develop atrial fibrillation following CABG (OR=2.165, p=0.05), had a higher re-admission rate (OR=2.307; p=0.032).

Discussion: Females had a grave clinical outcome following CABG. Women are at a higher risk to have an adverse effect following cardiovascular intervention, and we should be more aware of the possibly that women come to seek medical attention when they are sicker and at a higher risk compared to men.
