Resume

Actuality. Atrial fibrillation significantly increases the risk of stroke, while vitamin K antagonists cannot always be used due to contraindications. Apixaban is a potential alternative, but data on its comparative effectiveness with aspirin in such patients remain insufficient. This study aims to assess the efficacy and safety of apixaban in preventing stroke and systemic embolism in this patient group. Objective: To evaluate the efficacy and safety of apixaban compared to aspirin in patients with atrial fibrillation who are contraindicated for vitamin K antagonists. Materials and Methods: A total of 103 patients were included in the study and randomized into two groups: apixaban (n=52) and aspirin (n=51). The incidence of stroke, systemic embolism, mortality, and bleeding risk were analyzed. Statistical analysis was performed using the chi-square test and relative risk (OR) estimation with a 95% confidence interval (CI). Results: Stroke or systemic embolism occurred significantly less frequently in the apixaban group (1.9% vs. 8%, p<0.001). The incidence of ischemic stroke was also lower (3.8% vs. 10%, p<0.001). The rate of major bleeding events remained low and did not differ between the groups (1.9% vs. 2%, p=0.88). Hospitalization due to cardiovascular causes was lower in the apixaban group (13.5% vs. 22%, p<0.001). Conclusion: Apixaban is a more effective option for preventing stroke and systemic embolism in patients with atrial fibrillation who are contraindicated for vitamin K antagonists, while not increasing the risk of major bleeding.

Keywords: atrial fibrillation, apixaban, aspirin, stroke, systemic embolism.
