Added Predictive Ability of the CHA 2 DS 2 VASc Risk Score for Stroke and Death in Patients With Atrial Fibrillation

Added Predictive Ability of the CHA2DS2VASc Risk Score for Stroke and Death in Patients With Atrial Fibrillation

Background—The objective of this study was to evaluate the added predictive ability of the CHA2DS2VASc prediction rule for stroke and death in a nonanticoagulated population of patients with atrial fibrillation. Methods and Results—We included 1603 nonanticoagulated patients with incident atrial fibrillation from a Danish prospective cohort study of 57 053 middle-aged men and women. The Net Rec...

Long‐Term Stroke Risk Prediction in Patients With Atrial Fibrillation: Comparison of the ABC‐Stroke and CHA 2 DS 2‐VASc Scores

BACKGROUND The ABC-stroke score (age, biomarkers [N-terminal fragment B-type natriuretic peptide, high-sensitivity troponin], and clinical history [prior stroke/transient ischemic attack]) was proposed to predict stroke in atrial fibrillation (AF). This score was derived/validated in 2 clinical trial cohorts in which patients with AF were highly selected and carefully followed-up. However, the ...

Added predictive ability of the CHA2DS2VASc risk score for stroke and death in patients with atrial fibrillation: the prospective Danish Diet, Cancer, and Health cohort study.

BACKGROUND The objective of this study was to evaluate the added predictive ability of the CHA(2)DS(2)VASc prediction rule for stroke and death in a nonanticoagulated population of patients with atrial fibrillation. METHODS AND RESULTS We included 1603 nonanticoagulated patients with incident atrial fibrillation from a Danish prospective cohort study of 57 053 middle-aged men and women. The N...

Ischemic Stroke Risk in Patients With Atrial Fibrillation and CHA2DS2-VASc Score of 1

Predictive value of the CHA2DS2-VASc score in atrial fibrillation patients at high risk for stroke despite oral anticoagulation.

INTRODUCTION AND OBJECTIVES The risk of stroke in atrial fibrillation is heterogeneous and depends upon underlying clinical conditions included in current risk stratification schemes. Recently, the CHA(2)DS(2)-VASc score has been included in guidelines to be more inclusive of common stroke risk factors seen in everyday clinical practice, and useful in defining "truly low risk" subjects. We aime...
