Popis: The clinical impact of ABO blood type on cardio-cerebrovascular outcomes in patients undergoing dialysis has not been clarified. A total of 365 hemodialysis patients participated in the current study. The primary endpoint was defined as a composite including cardio-cerebrovascular events and cardio-cerebrovascular death. The primary endpoint was observed in 73 patients during a median follow-up period of 1182 days, including 16/149 (11%) with blood type A, 22/81 (27%) with blood type B, 26/99 (26%) with blood type O, and 9/36 (25%) with blood type AB. At baseline, no difference was found in the echocardiographic parameters. Multivariable Cox regression analyses revealed that blood type (type A vs. non-A type; hazard ratio (HR): 0.46, 95% confidence interval (95% CI): 0.26–0.81, p = 0.007), age (per 10-year increase; HR: 1.47, 95% CI: 1.18–1.84), antiplatelet or anticoagulation therapy (HR: 1.91, 95% CI: 1.07–3.41), LVEF (per 10% increase; HR: 0.78, 95% CI: 0.63–0.96), and LV mass index (per 10 g/m2 increase; HR: 1.07, 95% CI: 1.01–1.13) were the independent determinants of the primary endpoint. Kaplan–Meier curves also showed a higher incidence of the primary endpoint in the non-A type than type A (Log-rank p = 0.001). Dialysis patients with blood type A developed cardio-cerebrovascular events more frequently than non-A type patients.
