研究目的: |
1. 评价NAPT策略用于TAVR术后1年无长期接受抗凝或抗血小板治疗指征人群抗栓治疗的安全性及有效性; 2. 探究影响TAVR术后患者发生出血或缺血性事件的危险因素,初步建立适用于TAVR术后患者长期出血及缺血性事件风险的预测评分系统; 3. 探究TAVR术后出血及缺血事件的危险分层及管理流程。 |
||||||||||||||||||||||
|
Objectives of Study: |
1. To evaluate the safety and efficacy of cessation antithrombotic drugs (NAPT) after 1 year of TAVR in patients without indications for long-term anticoagulation or antiplatelet therapy; 2. To explore the risk factors of bleeding or ischemic events in patients after TAVR, and to establish a predicting system for the long-term risk of bleeding and ischemic events after TAVR; 3. To establish a risk stratification and management process for bleeding and ischemic events after TAVR. |
