Objectives To determine the accuracy of CHADS2 and CHA2DS2-VASc tools for predicting
ischaemic stroke or transient ischaemic attack (TIA) and death in patients without a history of …

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 …

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

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 …

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 …

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 Several studies have compared the discriminative performances of CHA 2 DS 2-
VASc and ATRIA scores, but the results are still disputed. Therefore, we aimed to explore …

Aims Anticoagulants are the mainstay treatment for stroke prevention in patients with non-
valvular atrial fibrillation (NVAF), and the CHA2DS2-VASc score is widely used to guide …

Abstract Aims The CHA2DS2-VASc score is a modification of the CHADS2 score that aims to
improve stroke risk prediction in patients with atrial fibrillation (AF) by adding three risk …
