A new study exploring ethnic differences in stroke risk for people with atrial fibrillation (AF) showed that Mexican American stroke survivors with afib were more than twice as likely to have another stroke as comparable non-Hispanic white stroke survivors with afib.
Researchers were surprised by the study’s finding that severity of recurrent stroke is also greater in Hispanics. Why the difference? Several observations raise interesting possibilities, including differences in use and control of anticoagulants such as warfarin.
