ContextPatients who have atrial fibrillation (AF) have an increased risk of stroke, but their
absolute rate of stroke depends on age and comorbid conditions. ObjectiveTo assess the …

Background The risk stratification score, which includes Congestive heart failure,
Hypertension, Age≥ 75 [doubled], Diabetes, Stroke [doubled]-Vascular disease, Age 65-74 …

Background and Purpose—The CHA2DS2-VASc score aims to improve risk stratification of
ischemic stroke among patients with atrial fibrillation to identify those who can safely forego …

BACKGROUND Our objective was to determine stroke and thromboembolism event rates in
patients with atrial fibrillation (AF) classified as “low risk” using the Anticoagulation and Risk …

Background and purpose: The CHADS2 and CHA2DS2‐VASc scores are useful to stratify
embolic risks in patients with non‐valvular atrial fibrillation (NVAF) and to identify patients …

The main mechanism of the CHADS2 and CHA2DS2‐VASc scores to predict stroke in
nonvalvular atrial fibrillation (NVAF) is still controversial. We evaluated the association of the …

Abstract Aims The CHA2DS2VASc score is used to evaluate the risk of thromboembolic
events in patients with non-valvular atrial fibrillation. We assessed the prognostic yield of …

Background Oral anticoagulation (OAC) therapy guidelines recommend using CHA2DS2-
VASc to determine OAC need in atrial fibrillation (AF). A usable tool, CHA2DS2-VASc is …

Stroke and CHA2DS2‐VASc Score= 0. Objectives: Patients with atrial fibrillation (AF) and a
CHA2DS2‐VASc score= 0 have a very low risk of stroke and current guidelines even …

Stroke Risk Stratification. Introduction: Appropriate stroke risk stratification is essential to
ensure suitable tailoring of antithrombotic therapy. The objective of this study was to assess …
