Mexican-Americans With Heart Rhythm Disorder Have Increased Risk for Second Stroke
Mexican-American stroke survivors with a heart rhythm disorder have more than twice the risk for another stroke compared to non-Hispanic whites, according to a study published in Stroke: Journal of the American Heart Association.
Mexican-Americans' recurrent strokes are also more likely to be severe, though they don't have a greater risk of death after stroke, researchers said.
Researchers compared 88 Mexican-American and 148 non-Hispanic white stroke survivors who had atrial fibrillation, a disorder in which the heart's upper chambers (called the atria) beat irregularly and don't pump blood effectively, possibly causing blood to pool within the atria and blood clot formation in the heart.
They found that the likelihood of suffering another stroke during the study follow-up period was more than double for Mexican-Americans than for non-Hispanic whites. Although stroke recurrence was higher and strokes were more severe among Mexican-Americans, death rates didn't differ between the two groups.
National Stroke Association’s mission is to reduce the incidence and impact of stroke by developing compelling education and programs focused on prevention, treatment, rehabilitation and support for all impacted by stroke.
