Introduction- Many series have demonstrated that women undergoing CABG appear to have higher morbidity and mortality than men, therefore this study was designed to answer the questions of whether such differences actually exist or not in the pre- and postoperative period. Material- This study was carried out from January to end of May 2000 at our cent. 201 consecutive patient undergoing CABG were selected. Exclusion criteria included previous CABGS. We used antegrade and retrograde cardioplegia during surgery with conventional anesthesia in all patients, any complication during the pre- and postoperative and hospital stay were recorded, and data were evaluated statistically using SPSS software. Results- 201 patients undergoing CABG were evaluated. 46% were women and 54% were men with mean age of 51 years. In comparison with men, women were older, had higher incidence of hypertension, diabetes, but otherwise similar for early complications. However the duration of hospital stay was different, with 13.9±0.4 days for men and 18.4 ± 1 days for women, p<0.001. Conclusion- In spite of similar postoperative complications and mortality in men and women, the number of grafts and hospital stay was different (Iranian Heart Journal. 2002, 2003; 3(4)&4(1): 17-20) `
