Briefly, the thrombosis and bleeding rate increased with the increase in BMI levels.

Discussion To the best of our knowledge, our study is the first to show statistically increased risks for thrombotic incidents in Chinese obese patients with atrial fibrillation anticoagulated with low dose DOACs. Using DOACs might be alternatives for the treatment of patients with high BMI referred to catheter ablation of atrial fibrillation. We.Meanwhile, for Chinese patients with higher BMI (BMI 25kg/m2), rivaroxaban of lower dosage (15 mg) might be not enough to prevent thrombosis and a higher dose was suggested. months.
