Key result
The prevalence of atrial fibrillation was markedly lower in Singapore-Asian patients with heart failure compared to NZ-Europeans (24% vs 63%; p<0.001).
Why the study?
Ethnic differences in the prevalence of atrial fibrillation in heart failure remain unclear.
Does the prevalence and clinical correlates of atrial fibrillation differ between Asian and New Zealand-European patients with heart failure?
Population
1746 patients with validated HF across Singapore and New Zealand
Comparison
Different ethnicities (Singapore-Asians vs NZ-Europeans)
Design
Prospective observational study
Follow-up

Ethnic differences in AF prevalence among HF patients may affect screening and risk assessment; this cohort study leaves open mechanisms and generalizability.

Does the prevalence and clinical correlates of atrial fibrillation differ between Asian and New Zealand-European patients with heart failure?
Absolute Event Rate: 24% vs 63%
p-value: p=<0.001
There is a strikingly lower prevalence of atrial fibrillation among Asian compared with New Zealand-European patients with heart failure, with differing clinical correlates such as diabetes.
Tan et al. (2019) conducted an observational in Heart failure (n=1,746). Asian ethnicity vs. NZ-European ethnicity was evaluated on Prevalence of atrial fibrillation (p=<0.001). The prevalence of atrial fibrillation was markedly lower in Singapore-Asian patients with heart failure compared to NZ-Europeans (24% vs 63%; p<0.001).
