Factors Affecting Bleeding in Patients with Atrial Fibrillation Receiving Rivaroxaban : A Multicenter Matched Case-Control Study
Main Article Content
Abstract
Objective: To investigate factors affecting bleeding in patients with atrial fibrillation receiving rivaroxaban. Methods: This research was a multicenter, matched case-control study. Data were collected from patients with atrial fibrillation receiving rivaroxaban at King Chulalongkorn Memorial Hospital and Ramathibodi Hospital from October 1, 2013 to September 30, 2021. Case-control pairs were matched (1:1) with gender and age. The factors affecting bleeding were analyzed using multiple logistic regression. Results: A total of 182 patients were divided into two groups. Ninety-one case-patients with bleeding consisted of 20 patients with major bleeding, 45 patients with clinically relevant non-major bleeding and 26 patients with minor bleeding. The control group was 91 patients without bleeding. Factors significantly affecting bleeding included history of bleeding (adjusted OR: 11.23, 95%CI= 3.94, 31.97; P < 0.001) and hypoalbuminemia (adjusted OR: 2.22, 95%CI=1.01, 4.89; P = 0.047) after adjusted with rivaroxaban daily dose, creatinine clearance, inappropriate dose with too high dose, anemia, and drug interactions. Conclusion: Factors affecting bleeding in patients with atrial fibrillation receiving rivaroxaban were history of bleeding and hypoalbuminemia. Therefore, patients with these factors should be monitored to reduce risk of bleeding and improve safety of rivaroxaban use.
