CHA2DS2-VASc score

From WikiLectures

CHA2DS2-VASc score is a scale used to assess the risk of thromboembolic complications for patients suffering atrial fibrillation. It replaced the older version of the CHADS2 score, which underestimated some indications of anticoagulants compared to this version. In the secondary prevention of ischemic CMP the patient automatically has at least 2 points (risk of recurrence > 10 % / year) and he is indicated for anticoagulant therapy.

C cardiac failure (EF < 40%) 1
H hypertension 1
A2 age ≥ 75 2
D diabetes mellitus 1
S2 TIA/iCMP (stroke) 2
V vascular diseases (IM/ICHS, ICHDK, AS carotid, aorta) 1
A age 65–74 1
Sc female sex (sex category) 1
  • Maximum number obtained is 9, when the risk of thromboembolism is the highest.
  • Patients having score ≥ 2 are indicated for anticoagulant therapy.
  • Patients having score 1 have highly recommended anticoagulant therapy.
  • Patients without risk factors do not require treatment or are given antiplatelet agents (ASA).
