Atrial Fibrillation Risk Score for Stroke and Stroke or Death
From The Framingham Heart Study
Risk Factors: Patient With New-Onset Atrial Fibrillation Enter Values Here
Age (years)
Systolic Blood Pressure (mmHg)
Cigarette Smoker in Past Year
Prior Stroke/Transient Ischemic Attack (TIA)
History of Congestive Heart Failure or Myocardial Infarction
Significant Murmur (grade 3/6 or higher systolic, any diastolic)
Electrocardiographic Left Ventricular Hypertrophy (LVH)
Your 5-Year Risk of Stroke
Your 5-Year Risk of Stroke or Death
This score is not applicable to patients with rheumatic mitral stenosis, current warfarin use, or prior stroke/TIA in the setting of AF.  The score may underestimate the risk for individuals with left ventricular dysfunction.  The above equation-based risk score may differ from the point-based risk score contained in the manuscript, particularly for patients with uncommon combinations of characteristics. Covariates used for the stroke score are gender, age, blood pressure, diabetes, and prior stroke/TIA; all above covariates except gender and prior stroke/TIA are used for stroke/death.  These functions and programs were prepared by Ralph B. D'Agostino, Lisa M. Sullivan and Joseph M. Massaro of Boston University and The Framingham Heart Study. JAMA. 2003;290:1049-1056.
