Implication
Ethnic differences in device-detected AF persist with monitoring; supports targeted research into mechanisms beyond ascertainment bias but should not yet alter practice.
Structured PICO
Does non-European ethnicity affect the incidence of device-detected atrial fibrillation in patients with hypertension and implanted cardiac devices?
P
Population
2,580 patients with hypertension but no history of atrial fibrillation, with an implanted pacemaker or defibrillator, enrolled across 23 countries. Ethnic groups included Europeans (n=1900), black Africans (n=73), Chinese (n=89), and Japanese (n=105).
I
Intervention
Non-European ethnicity (black African, Chinese, Japanese)
C
Comparator
European ethnicity
O
Outcome
Incidence of device-recorded atrial fibrillation (AF) episodes >190/min, lasting either for >6 minutes or >6 hours in durationhard clinical
Black African, Chinese, and Japanese patients have a significantly lower incidence of device-detected atrial fibrillation compared to Europeans, demonstrating that previously observed ethnic differences are not solely due to ascertainment bias.
