Most of the published literature on Atrial fibrillation (AF) originates from the northern hemisphere and mainly involves Caucasian patients, with limited studies in certain ethnicities and races. This scoping review was conducted to collect and summarize the pertinent evidence from the published scientific literature on AF in South Asians and Middle Eastern Arabs. MEDLINE, Embase and CENTRAL databases were included in our search. After screening 8995 records, 55 studies were selected; 42 from the Middle East and 13 from South Asia. Characteristics of the included studies were tabulated, and their data were summarized for study design, setting, enrolment period, sample size, demographics, prevalence or incidence of AF, co-morbidities, risk factors, AF types and symptoms, management, outcomes, and risk determinants. Identified literature gaps included a paucity of community or population-based studies that are representative of these two ethnicities/races. In addition, studies that addressed ethnic/racial in-equality and access to treatment were lacking. Our study underscores the urgent need to study cardiovascular disorders, particularly AF, in South Asians and Middle Eastern Arabs as well as in other less represented ethnicities and races.
