GENDER DIFFERENCES IN MYOCARDIAL REVASCULARIZATION IN INDIVIDUALS WITH ACUTE CORONARY SYNDROME AFTER CORONARY ARTERY BYPASS SURGERY

Abstract

The purpose of this study was to study the gender differences in the frequency of major cardiovascular and cerebrovascular events (MACCE), cardiac mortality, mortality from all other causes, and to study the relationship between these conditions and risk factors in patients after CABS. Materials and methods. The study included 717 patients after the CABS, of whom 596 were male and 121 female. Patients admitted to hospital with acute coronary syndrome (ACS) and only those undergoing CABS surgery participated in the study. All clinical data on demographic characteristics, risk factors, and complications were selected and the survival and mortality analysis was performed retrospectively. The results. In assessing the age indicator, it was found that females (59.9±7.3 years) were significantly older than males (56.3±8.2 years) (p=0.00012). In the estimation of the 30-day mortality rate, it was shown that this indicator was 3.4% for women and 0.5% for men, the differences were statistically significant (p=0.004). Identical differences were also observed for 1-year mortality, as this indicator was 3.5% for women, while for men it was 0.7% and significantly lower (p=0.012). The 5-year MACCE percentage was 19% for women and 16.9% for men, i.e. the difference was not statistically significant (p=0.585). Conclusion. The main finding of this study was the difference between the profiles of female and male populations of preoperative patients after CABS. As in other studies in this area, and in this study, female patients were older, more likely to have AH, DM, obesity and anaemia than male patients.
