Purpose
In this retrospective study, we investigated the demographic data and evaluated our early postoperative results of premenopausal and postmenopausal females who underwent coronary artery bypass graft surgery (CABG).
Methods
A total of 730 female patients who underwent CABG between April 2004 and January 2012 were included in the study. Patients were divided into two groups based on whether they were pre- (group 1) or postmenopausal (group 2). The groups were compared in terms of the demographic and peri-operative parameters.
Results
Smoking and the preoperative hematocrit levels were higher in group 1, whereas the incidence of hypertension and obesity and the European system for cardiac operative risk evaluation values were higher in group 2 (p values <0.01; <0.01; <0.01; 0.004 and <0.01 respectively). The utilization of a left internal mammary artery graft and the postoperative drainage volumes were higher in group 1; however, the number of grafts per patient, cardiopulmonary bypass duration, number of patients who needed inotropic support, blood transfusion volumes, the duration of ventilatory support and the hospital stay were higher in group 2 (p values 0.038; 0.040; 0.026; 0.032; 0.014; 0.001; <0.01 and <0.01, respectively).
Conclusions
Although the mortality rates were not significantly different, postmenopausal patients require more intensive postoperative care in comparison to premenopausal patients following CABG.
