Stroke Risk Model
A Prognostic Model for Stroke Risk in the Elderly: The stroke model below gives an approximate prediction of the risk of stroke over the next 5 years for people over 70 who have not had a stroke before. This is not a substitute for advice from a medical professional. Only your doctor can tell you what treatments may be suitable to reduce your risk of stroke.
The maximum risk score in the CHS cohort was approximately 50 points. The stroke model has not been tested at higher risks than this and may become unreliable. The construction of the model is described in the paper S-63, Prediction of the Risk of Stroke in the Elderly.
