研究设计:

队列研究 

Study design:

Cohort study 

研究目的:

(1)分析非瓣膜性房颤患者左心耳血栓形成的危险因素,探索能够独立预测LAAT的临床和实验室指标。 (2)评估现有的CHA2DS2-VASc评分系统在预测NVAF患者LAAT中的效能。 (3)构建并验证包含新发现的独立危险因素的改进版血栓栓塞预测量表,比较其与CHA2DS2-VASc评分系统的预测价值。  

Objectives of Study:

(1) To analyze the risk factors of left atrial appendage thrombosis in patients with nonvalvular atrial fibrillation, and to explore clinical and laboratory indicators that can independently predict LAAT. and (2) to evaluate the efficacy of the existing CHA2DS2-VASc scoring system in predicting LAAT in patients with NVAF. (3) To construct and validate an improved thromboembolism prediction scale containing newly discovered independent risk factors, and to compare its predictive value with the CHA2DS2-VASc scoring system.
