RESUMO

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. METHODS: The study was designed as a retrospective cohort study and included a total of 204 elderly patients aged > 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).

RESUMO

INTRODUCTION: Aortic valve replacement (AVR) is often recommended for patients with severe aortic stenosis or chronic aortic regurgitation. These conditions result in remodeling of the left ventricle, including increased interstitial fibrosis that may persist even after AVR. These structural changes impact left ventricular (LV) mechanics, causing compromised LV diameter to occur earlier than reduced LV ejection fraction (LVEF). The aim of this study was to examine the effect of left ventricular end-diastolic diameter (LVEDD) and its role in aortic expansion one year after AVR. METHODS: Sixty-three patients who underwent AVR were evaluated. All patients underwent standard transthoracic echocardiography, which included measurements of the ascending aorta, aortic root, LVEF, and LVEDD before the surgery and one year postoperatively. Correlations between these variables were calculated. RESULTS: All patients underwent AVR with either a mechanical or biological prosthetic aortic valve. Following AVR, there was a significant decrease in the dimensions of the ascending aorta and aortic root (both P=0.001). However, no significant changes were observed in LVEDD and LVEF. Correlations were found between the preoperative ascending aortic size and the preoperative and one-year postoperative LVEDD (r=0.419, P=0.001 and r=0.320, P=0.314, respectively). Additionally, there was a correlation between the postoperative ascending aortic size and the preoperative and one-year postoperative LVEDD (r=0.320, P=0.003 and r=0.136, P=0.335, respectively). CONCLUSION: The study findings demonstrate a significant correlation between the size of the aortic root and ascending aorta, before and after AVR. Additionally, a notable correlation was observed between postoperative LVEDD and the size of the aortic root.
