The CHADS2 score is a historic clinical prediction rule for estimating the risk of stroke in patients with non-rheumatic atrial fibrillation. It scores Congestive heart failure, Hypertension, Age ≥75, Diabetes mellitus, and prior Stroke or TIA. While foundational to modern cardiology, most major guidelines (AHA/ACC, ESC) now recommend the CHA2DS2-VASc score for better discrimination of truly low-risk patients.
Although largely superseded, CHADS2 is still referenced in older literature, legacy electronic health records, and certain specialized studies (e.g., specific post-op AF protocols). However, a CHADS2 score of 0 does not reliably mean the patient is low risk; hence the shift to CHA2DS2-VASc.
