ABSTRACT

In this study, we aimed to investigate the relationship between long-term mortality and survival in patients with ABO blood group, and acute coronary syndrome.

This observational study was carried out in two tertiary hospitals. A total of 192 patients followed up for 72 months due to acute coronary syndrome, and showing a balanced distribution for ejection fraction, additional diseases and age, were included in the study.

The survival rate was evaluated in 72 months of follow-up. In the survival analysis made according to individual blood groups; a statistically significant difference was not detected between groups. When the patients were divided into two groups, mortality rates were 24.39% in patients with, and 15.23% without blood group O (p>0.05). Although not statistically significant, in patients with blood group O, an increasing tendency was observed in 72 month-mortality rates (p>0.05). Any association between Rh antigen and survival was not found in this study (p=0.79).

Although it could not reach the limit of statistical significance, a decreasing tendency in long-term survival was observed in acute coronary syndrome patients with blood group O compared to those without The results should be confirmed by larger prospective studies.
