ABSTRACT
INTRODUCTION:
Numerous studies have shown that
women undergoing
coronary artery bypass graft surgery present higher mortality rate during
hospitalization, and often
complications when compared to
men.
OBJECTIVE:
To compare the
mortality of
men and
women undergoing
coronary artery bypass graft surgery and identify factors related to differences occasionally found.
METHODS:
Retrospective
cohort study conducted with 215 consecutive
patients who underwent coronary bypass
surgery.
RESULTS:
Women had a higher average age. Low body surface and
dyslipidemia were more prevalent in
women (1.65 vs . 1.85, P<0.001 53% vs . 30%, P =0.001), whereas
history of
smoking and previous
myocardial infarction were more prevalent in
men (35% vs .14.7%, P =0.001; 20% vs . 2.7%, P =0.007). Regarding
complications in the
postoperative period, there was a higher rate of
blood transfusions in
women. The overall mortality rate was 5.6%, however there was no statistically significant difference in
mortality between
men and
women. It was observed that among the
patients who died, the average
body surface area was lower than that of
patients who did not have this complication.
CONCLUSION:
There was no difference in
mortality between the sexes after
coronary artery bypass graft in this service.
