Information
CHA2DS2-VASc score is for estimating the risk of stroke in patients with Atrial Fibrillation (AF). It is used to guide clinical decision-making regarding anticoagulation therapy in patients with AF, with higher scores typically warranting stronger consideration for anticoagulation to prevent stroke. This scoring system provides a more detailed assessment of stroke risk compared to CHADS2.
CHA2DS2-VASc Score for Atrial Fibrillation Stroke Risk
Total Score Annual Stroke Risk
0 Low
(0% - Consider no anticoagulation)
1 Low
(1.3% - Consider anticoagulation based on patient factors)
2 or more Moderate to high
(2.2% or higher - Anticoagulation therapy typically recommended)

Information
HAS-BLED Score is used to evaluate bleeding risk, in particular for patients on anticoagulation therapy. It incorporates various risk factors: hypertension, renal and liver disease, history of stroke, previous major bleeding or predisposition to bleeding, labile INR, age over 65, and the use of medications or alcohol that increase bleeding risk. HAS-BLED Score guides decision-making in anticoagulant therapy, carefully weighing the risk of bleeding against the therapeutic benefits. A higher score suggests a greater risk, necessitating a thorough review of the patient's treatment plan and closer monitoring for potential bleeding complications.
