Identifying patients at high risk for stroke despite anticoagulation: a comparison of contemporary stroke risk stratification schemes in an anticoagulated atrial fibrillation cohort. CHF = 1pt As shown in the diagram below, CHADS2-VASc classifies the same patient group into a higher risk category compared to CHADS2.1. . Note how the CHADS2-VASc scoring system classifies more patients into the "high risk" category compared to CHADS2. Refining clinical risk stratification for predicting stroke and thromboembolism in atrial fibrillation using a novel risk factor-based approach: the euro heart survey on atrial fibrillation. First published in 2001, the CHADS 2 score (congestive heart failure, hypertension, age 75 years, diabetes mellitus, stroke [double weight]) was developed to more accurately predict the risk. 65 0 65-74 +1 75 +2 sex female +1 male 0 chf history no 0 yes +1 hypertension history no.

Mathematics is the study of numbers, shapes, and patterns. The CHA 2 DS 2 -VASc score contains more risk factors and has a greater range of points, thus switching to the CHA 2 DS 2 -VASc score will increase the number of patients eligible for anticoagulation. It's arguably the best validated and is consistently, Expert instructors will give you an answer in real-time. It is generally recommended that patients with a score >2 be started on warfarin, as the benefits of ischemic stroke prevention outweigh the bleeding risk.
