Abstract:
Nonvalvular atrial fibrillation (NVAF) is the most common type of arrhythmia and an independent risk factor for ischemic stroke.Warfarin effectively decreases the risk factors for ischemic stroke in patients with NVAF,but substantially increases the risk for severe bleeding.Currently,most clinical guidelines recommend using the CHADS2 score for stroke risk stratification in NVAF patients to guide antithrombotic treatment.Although its application is simple and convenient,the CHADS2 score has been debated because of many limitations; especially some common stroke risk factors were not included.By comparison,the CHA2 DS2-VASc scores have included more risk factors for stroke.It can better identify the truly low-risk patients.Among the AF patients with CHADS2 score of 0 to 1,CHA2DS2-VASc scores may provide the important information for stroke risk,and thus help the decision-making of the anticoagulant therapy.
