2666 Stroke October 2017 validation studies showed fair-to-good predictive ability of the
CHADS2 score, with C statistics ranging between 0.56 and 0.82. 18 Despite these validation …

Background: Previous studies report that CHADS2 and CHA2DS2-VASc risk scores have
similar discriminating ability (C statistic∼ 0.6). Recently a clinically based risk score, the …

North American and European guidelines on atrial fibrillation (AF) are conflicting regarding
the classification of patients at low/intermediate risk of stroke. We aimed to investigate if the …

Atrial fibrillation (AF) is a highly prevalent arrhythmia associated with a fivefold increase in
the risk of stroke. However, this risk is not homogeneous and varies considerably depending …

Objective To perform a systematic review and meta-analysis of the predictive abilities of
CHADS 2 and CHA 2 DS 2-VASc in stroke and thromboembolism risk stratification of atrial …

Background Both US and European guidelines recommend use of the CHA 2 DS 2-VASc
rather than CHADS 2 score for stroke risk stratification in atrial fibrillation (AF). However, the …

Two validated scoring systems for predicting embolic risk, CHADS2 and CHA2DS2-VASc,
contribute to optimizing antithrombotic prescription practices in patients who have atrial …

Atrial fibrillation (AF) is a major risk factor for stroke and thromboembolism but this risk is not
homogeneous among patients with AF, being dependent upon associated risk factors such …

Abstract Purpose of Review Stroke prevention is the cornerstone of atrial fibrillation (AF)
management and the anticoagulation decision is currently based on CHA 2 DS 2-VASc risk …

The traditional approach was to use risk stratification schemes to focus on identifying high-
risk patients to be targeted for OAC with an “inconvenient” drug, warfarin (a vitamin K …
