【 摘 要 】

OBJECTIVES: The aim of this study was to investigate bleeding risk in patients treated with VKAs after ground-level falls, considering the type and severity of bleeding. 65 years treated for AF continuously with warfarin for more than 3 years. Data were obtained from hospital registries in Bratislava, Slovakia. A 5-year assessment of death/survival was performed to determine mortality.RESULTS: There was no statistically significant difference in severe bleeding (2.13 % with falls vs 2.55 % without, p = 1) and 5-year mortality (45 % and 38 % respectively, p = 0.3987) based on the presence of falls. Multivariate analysis, after adjustment for age, CHA2DS2VASc, HASBLED, stroke history, labile INR and number of falls showed that only HASBLED score was a statistically significant contributor (CI: 1.0245 – 1.0919, p = 0.0007) to severe bleeding. There was statistically significant difference in severe bleeding (18 % vs 0 %, p = 0.0132) between patients suffering from spontaneous and bleeding after falls and also when comparing individual bleeding episodes (12 % vs 1 %, p < 0.0001). There was no statistically significant difference in 5-year mortality between the two groups (43 % vs 42 % respectively, p = 0.3931).CONCLUSIONS: Our results show that occurrence of falls in AF patients treated with VKAs have no significant impact on the incidence of severe bleeding and 5-year mortality and that spontaneous bleeding was associated with a significantly higher risk of severe bleeding compared to bleeding after falling (Tab. 4, Ref. 30).
