Comparative assessment of risk factors and hospital results in male and female patients underwent to coronary artery bypass surgery

: There are controversial data on relatively unfavorable effect of female gender on postoperative mortality of patients underwent to coronary artery bypass grafting (CABG). In order to assess risk factors and hospital outcomes after elective CABG we studied retrospectively data on patients who had undergone CABG in Sani Konuogly medical center (Gasiatep, Turkey) during the period from March 2002 to March 2010. For elimination of unfavorable effect of old age we included into analysis data from patients younger than 65 years. In accordance with study aim all patients (n=2692) were divided into two gender groups 1966 men (mean age 54,01 years) and 726 women (mean age 54.35 years). Diabetes (48.3 and 26.9%; p=0.0001), arterial hypertension (76.6 and 28.4%; p=0.00001), and obesity (50 42%; p=0.03) were more frequent among women while smoking (44.5 and 10.3%; p=0.0001), hyperlipidemia (37.6 and 21.5%; p=0.0002), and history of myocardial infarction (31.3 and 17.3%; p=0.06) were more often registered among men. Mortality was insignificantly higher in women (1.6 and 0.9%; p=0.06). Perioperative Q-wave myocardial infarction was more frequent among men than among women (1.5 and 0.4% respectively; p=0.04). It is necessary to conduct prospective well controlled study for exclusion of gender influences on perioperative outcomes in patients subjected to CABG .
