研究目的:

心房颤动是临床上最常见的心律失常之一,导管消融是治疗心房颤动的主要手段之一。但导管消融成功是否能降低血栓栓塞风险尚无定论,迄今国际上主流指南仍均建议无论房颤是否消融成功,对于CHA2DS2-VASC评分≥1分的患者仍需要长期抗凝治疗。本研究旨在明确房颤消融成功是否能够降低房颤患者血栓栓塞的风险,为相关指南提供依据。  

Objectives of Study:

The global burden of atrial fibrillation (AF) is well-documented, with current therapeutic strategies, including catheter ablation (CA), at the forefront of clinical management. However, whether successful catheter ablation can reduce the risk of thromboembolism has not yet been concluded. So far, mainstream international guidelines still recommend long-term anticoagulation therapy for patients with CHA2DS2-VASC score ≥1 regardless of successful ablation of atrial fibrillation. The aim of this study is to determine whether successful ablation of atrial fibrillation can reduce the risk of thromboembolism in patients with atrial fibrillation and provide evidence to relevant guidelines.
