Overview

AF prevalence in China signals underdiagnosis risk; leaves open anticoagulation optimization pending prospective studies.

Structured PICO

P
Population
29,079 adults aged ≥30 years (mean age 52.5, 46.6% male) from 14 population-based cohorts across 13 provinces in mainland China.
O
Outcome
Prevalence of atrial fibrillation and its risk factors

The age-standardized prevalence of AF in mainland China is 0.65%, which is slightly lower than in Western countries, but AF remains a significant independent risk factor for stroke with poor rates of anticoagulation.

Limitations

  • Cross-sectional design limits causal inference
  • Lack of biochemical examinations (e.g., blood tests for thyroid function, blood sugar, blood lipid) leading to low reported diabetes prevalence
  • Wide confidence intervals for RHD due to small number of cases
  • Difficulty in discovering paroxysmal AF with a single ECG, potentially underestimating true prevalence
