How to assess and manage stroke risk in atrial fibrillation

How to assess and manage stroke risk in atrial fibrillation

Mayo Clinic electrophysiologist Paul A. Friedman, M.D., and neurologist James P. Klaas, M.D., discuss stroke rates in atrial fibrillation with and without anticoagulation with Gayatri A. Acharya, M.D.

The risk scoring system most commonly used to determine which patients have a high enough stroke risk to warrant treatment is the CHA2DS2-VASc score, which rates risk based on congestive heart failure, high blood pressure, age, diabetes, previous stroke or clot, vascular disease, age and sex.

Approximately 20 percent of stokes are cardioembolic. Drs. Friedman and Klaas also discuss the other etiologies for stroke and the management of stroke risk.
