Insights
This study found a low prevalence of atrial fibrillation (AF) in Indo-Asian patients in Birmingham, highlighting a need for more research on this cardiac arrhythmia in non-Caucasian populations.
Area of Science:
- Cardiology
- Epidemiology
- Public Health
Background:
- Ethnic variations in cardiovascular disease are recognized, with higher rates of hypertension and stroke in Black/Afro-Caribbean populations and ischemic heart disease in Indo-Asians.
- Limited literature exists on the clinical epidemiology of atrial fibrillation (AF) in non-Caucasian groups.
- Understanding AF prevalence and characteristics in diverse ethnic populations is crucial for public health.
Purpose of the Study:
- To investigate the clinical features and management of atrial fibrillation (AF) in Indo-Asian patients.
- To determine the prevalence of AF within an Indo-Asian population in Birmingham.
- To address the scarcity of data on AF epidemiology in non-Caucasian individuals.
Main Methods:
- A survey of patients with known AF was conducted across six general practices in West Birmingham.
- The study population included 14,670 individuals of Indo-Asian ethnicity from a total practice population of 25,051.
- Data collected included patient demographics, AF type, comorbidities, and management strategies.
Main Results:
- Twelve Indo-Asian patients with known AF were identified, suggesting a prevalence of 0.6% in those aged over 50 years.
- Common comorbidities included heart failure (7 patients), ischemic heart disease (5 patients), and hypertension (3 patients).
- Only four patients were on anticoagulation therapy (warfarin), with six of the remaining eight taking aspirin, indicating suboptimal management.
Conclusions:
- The study identified a low prevalence of AF among Indo-Asian patients in the surveyed population.
- Current management of AF in this group appears suboptimal, with low rates of anticoagulation.
- Further research into the clinical epidemiology of AF in non-Caucasian populations is urgently needed due to public health implications.
Abstract:
Whilst there are recognised ethnic differences in cardiovascular disease, with a higher prevalence of hypertension and complications such as stroke amongst black/Afro-Caribbean populations, and ischaemic heart disease being more prevalent amongst Indo-Asians, the literature describing the clinical epidemiology of atrial fibrillation (AF) in non-caucasian groups is scarce. To survey the clinical features and management amongst Indo-Asian patients with known AF, we studied patients from six general practices in the west of Birmingham. The six general practices had a combined practice population of 25051, from which, the Indo-Asian population was 14670. A total of 12 Indo-Asian patients (six male, six female; mean age, 67 years; range, 42 to 95 years) with known AF were identified, suggesting a prevalence of AF in Indo-Asians aged >50 years of 0.6%. Six patients had chronic AF, two had recent onset (defined as onset
