The Difference between the Two Scores: Background and Idea • The Background of Two Scores • —— CHADS2 originated in the early days of the anticoagulant conc ept of non-valvular disease, and most patients did not receive antico agulant therapy. • —— CHA2DS2-VAS originated in Europe where anticoagulation th erapy is highly popular and standardized. • Two Scoring Concepts • —— CHADS2: Conduct risk stratification, identify high-risk patien ts, and anticoagulate high-risk patients. • —— CHA2DS2-VAS: Desalinate the risk stratification, find out the real low-risk, do not give low-risk patients anticoagulation, other are anticoagulant. Speech from the European Heart Conference in August 2011 Assessment of stroke risk in anticoagulation therapy for at rial fibrillation by consensus of Chinese experts "At present, CHASD2 scoring system is mainly used to assess stroke risk in China.CHADS2 scoring system is the most widely used evaluation tool in clinical application. With the increase of CHADS2 scoring system, the risk of ischemic stroke in patients with atrial fibrillation will gradually increase in the future.
