Background. This study was aimed to determine influence of gender on result of coronary artery bypass grafting. It is a retrospective analysis. Methods. Ninety six patients, 48 men and 48 women of similar body surface area operated between 1991 to 1997 were compared. Associated comorbid conditions were identical in both the groups, except that none of the women smoked. Results. One patient (2.08%) died in each group. (p=NS). Although left anterior descending artery was smaller in diameter in women as compared to men, it did not express higher operative risk in women. No statistically significant difference was observed in perioperative and post operative morbidity including hospital stay. Conclusion. This study does not support the view that women carry higher surgical risk in comparison to men of similar body surface area.

Despite several studies reporting a higher mortality rate for women undergoing isolated coronary artery bypass graft (CABG) surgery, this issue has not been completely clarified. The aim of the current study was to determine if sex differences in CABG surgery affect adjusted operative results and operative mortality. Between January 2005 and December 2012, 3756 consecutive patients (3009 men and 747 women) underwent isolated CABG at our institution. Women presented with older age, smaller BSA and higher rate of preoperative comorbidities. The propensity score methodology was used to obtain risk-adjusted outcome comparisons between the two groups. The distribution of preoperative variables among matched pairs (553 patients in both groups) was, on average, equal. Propensity-matched women received a similar number of distal anastomoses (P = 0.56), had similar rate of left internal thoracic artery (LITA) graft (P = 0.73) and comparable extracorporeal circulation (P = 0.61) and aortic cr...

BackgroundA prospective study of patients undergoing coronary artery bypass graft surgery (CABG) was conducted to examine differences in hospital mortality by sex. Outcome data on 3055 CABG patients undergoing operation between 1987 and 1989 were examined for differences in patient, disease, and treatment factors. Methods and ResultsOdds ratios (OR), risk differences, and 95% confidence intervals (CI95%) were calculated. Mortality rates for women (7.1%) and men (3.3%) differed, the OR (women versus men) being 2.23 (CI9%, 1.58 to 3.15). Women were older, more often diabetic, and had more urgent or emergent surgery; adjustment yielded an OR (women versus men) of 1.75 (CI95%, 1.17 to 2.63). Body surface area BSA) was associated with risk of death in both sexes (P=.007) and positively associated with coronary artery luminal diameters. After adjustment for BSA, sex was no longer significantly associated with mortality (OR [women versus men] of 1.18; CI95%, 0.72 to 1.95). Internal mammary...

The female gender has been shown as high-risk factor for mortality and morbidity. We sought to assess the influence of female gender on coronary artery bypass graft (CABG) surgery from our own experience. This is a retrospective analysis of prospectively collected database from a single centre. Patients were grouped according to gender and potential differences in pre-operative, intra-operative and post-operative factors were explored. Significant high-risk factors were then fitted in a multivariate model to account for differences in predicting gender influence on surgical outcomes. Two thousand eight hundred and four consecutive patients underwent isolated first-time CABG between February 2000 and December 2008; 562 (20%) patients were females. Pre-operatively, females were more likely to have significant comorbidities (age, congestive cardiac failure, hypercholesterolemia, hypertension, ischemic heart disease, peripheral vascular disease, pre-op arrhythmias, small body surface ar...
