Impact of the CHA2DS2-VASc Score on Anticoagulation Recommendations for Atrial Fibrillation

摘要: Abstract Background The Congestive heart failure, Hypertension, Age≥75 years, Diabetes mellitus, Stroke (CHADS 2 ) score is used to predict the need for oral anticoagulation stroke prophylaxis in patients with atrial fibrillation. Stroke, Vascular disease, Age 65-74 Sex category (CHA DS -VASc) schema has been proposed as an improvement. Our objective determine how adoption of CHA -VASc alters recommendations. Methods Between 2004 and 2008, 1664 were seen at University Virginia Atrial Fibrillation Center. We calculated CHADS scores each patient. 2006 American College Cardiology/American Heart Association/Heart Rhythm Society guidelines fibrillation management recommendations based on score, 2010 European Cardiology score. Results average age was 62±13 34% women. Average 1.1±1.1 1.8±1.5, respectively ( P 0001). classified 33% requiring anticoagulation. 53% For women, 31% had a score≥2, but 81% score≥2 = . Also, 32% women zero score≥2. men, 25% 39% Conclusion Compared more clearly defines Many patients, particularly older are redistributed from low- high-risk categories.
