The IMRS-VASc risk score is a predictor of stroke that was derived and validated in patients who have atrial fibrillation, so it applies only to AF patients.

Intermountain Healthcare does not guarantee the accuracy or predictability of the Risk Calculator. For further information about your health, please consult your physician.
