Atrial fibrillation may reach pandemic proportions in the next 2-3 decades. Factors that drive this phenomenon have been studied in predominantly White populations, leading to a significant underrepresentation of certain racial/ethnic groups in atrial fibrillation epidemiological studies. Most atrial fibrillation epidemiology studies suggest that the non-Hispanic Black population has a lower incidence/prevalence of atrial fibrillation, despite a higher risk factor burden (“Afib paradox”). At the same time, non-Hispanic Blacks have worse outcomes compared to the White population and underrepresented populations and women are less likely than White men to receive optimal guideline-based therapies for atrial fibrillation.
In this episode, CardioNerds Dr. Kelly Arps (Co-Chair Atrial Fibrillation series, Cardiology fellow at Duke University), Dr. Colin Blumenthal (Co-Chair Atrial Fibrillation series, CardioNerds Academy House Faculty Leader for House Jones, Cardiology fellow at the University of Pennsylvania), and Dr. Dinu-Valentin Balanescu (CardioNerds Academy Faculty for House Jones, rising internal medicine chief resident at Beaumont Hospital), discuss with Dr. Larry Jackson (cardiac electrophysiologist and Vice Chief of Diversity, Equity, and Inclusion in the Division of Cardiology at Duke University) about atrial fibrillation epidemiology and health equity, challenges and possible solutions to improving diversity in clinical trials, and race/ethnicity/sex/gender differences in the detection, management, and outcomes of atrial fibrillation.

This CardioNerds Atrial Fibrillation series is a multi-institutional collaboration made possible by contributions of stellar fellow leads and expert faculty from several programs, led by series co-chairs, Dr. Kelly Arps and Dr. Colin Blumenthal.

Pearls and Quotes - Atrial Fibrillation: Epidemiology, Health Equity, & The Double Paradox
Atrial fibrillation confers an enormous public health burden. It is estimated that it will reach pandemic proportions over the next 30 years, with potentially 100-180 million people worldwide suffering from this condition.Large epidemiological atrial fibrillation registries have very small populations of underrepresented groups. More diverse enrollment in clinical trials is essential and may be obtained by increasing diversity among research staff, principal investigators, and steering committees, and use of mobile/telehealth technologies to remove bias related to differences in presentation. The CardioNerds Clinical Trials Network specifically aims pair equitable trial enrollment with trainee personal and professional development.Most atrial fibrillation epidemiology studies suggest that the non-Hispanic Black population has lower incidence/prevalence of atrial fibrillation, despite higher risk factor burden. This “paradox” is likely due to a multifactorial process, with clinical differences, socioeconomic factors, and genetic factors contributing.Underrepresented populations are less likely than White patients to receive optimal guideline-based management of atrial fibrillation.
