Which of the following is a component of CHADS-VASc scoring for stroke risk?

• A. Sex category female
• B. Age 50-64
• C. Smoking status
• D. Body mass index

Answer: (A)

CHADS-VASc scoring estimates stroke risk by tallying several clinical factors: congestive heart failure, hypertension, age (65–74 adds 1, ≥75 adds 2), diabetes, vascular disease, prior stroke/TIA/thromboembolism, and sex category. Each factor adds points, and sex category (being female) contributes 1 point. This is why that option is the component being tested. The other choices don’t add points in this scheme: age 50–64 isn’t a scoring category, smoking status isn’t included, and body mass index isn’t part of CHADS-VASc.
