Can Our Blood Groups Determine Our Life Expectancy?
Background/aim: In this study, we aimed to investigate the relationship between long-term mortality and survival with ABO blood group in patients with acute coronary syndrome. Materials and methods: This observational study was carried out in two tertiary hospitals. 192 patients followed for 72 months due to acute coronary syndrome, showing a balanced distribution for ejection fraction, additional diseases and age, were included in the study. Results: The survival rate was evaluated in 72 months follow-up. In the survival analysis according to individual blood groups; there was no statistically significant difference between the groups. When the patients were divided into two groups, there was 24.39% mortality in those with O blood group and 15.23% mortality in those without O blood group (p>0.05). Although it was not statistically significant, in patients with O blood group, an increasing tendency was observed in 72 month mortality (p>0.05). There was no association between Rh antigen and survival in this study (p=0.79). Conclusion: Although it was not able to reach statistically significance limit, a decreasing tendency in long-term survival was observed in patients with O blood group compared to those without O blood group in patients with acute coronary syndrome. The results should be confirmed by larger prospective studies.
