Arrhythmias & electrophysiology
Association of Race and Ethnicity With Stroke and Mortality Outcomes in Atrial Fibrillation
Authors' conclusion
In a nationwide cohort of AF patients, we found significantly higher stroke rates for Black than White patients. Conversely, we observed significantly lower mortality rates for Asian, Black, and Hispanic patients than for White patients. Interventions to address factors associated with these disparities are essential.
