The CHADS2 score is the simplest and most commonly used stroke- risk assessment tool since its implementation 2001. This scale is used to determine whether or not anticoagulation therapy is required for patients with episodic atrial fib. A higher CHADS2 score is directly related to a greater risk of stroke. The level of risk from a thrombotic event is determined by a score which is tallied by including five common stroke risk factors; congestive heart failure, hypertension, age, diabetes, and history of stroke. If a patient is positive for any of these risk factors they receive one point with the history of stroke getting 2 points (Camm et al, 2010). C Congestive heart failure
H Hypertension
A Age >75 1
D Diabetes 1
S2 Hx of Stroke or TIA or Thromboembolism

Recommended Therapy

score = 0 low risk None or Aspirin score = 1–2 moderate/intermediate risk Aspirin, Warfarin, or eg. Rivaroxaban score of ≥3 high risk Warfarin or Dabigatran / Rivaroxaban The European Society of Cardiology guidelines recommend that if the patient has a CHADS2 score of >2, oral anticoagulation therapy such as warfarin, dabagitran, or rivaroxaban should be prescribed. If the CHADS2 score is 0-1, other stroke risk modifiers could be considered such as…
