Arrhythmias & electrophysiology
Secular trends in the incidence of atrial fibrillation across different ages and sexes in Taiwan from 2001 to 2021
Authors' conclusion
This study revealed complex secular trends of AF incidence in the past 21 years, with decreasing overall SIRs but increasing annual IRs in younger populations. The intricate interplay between AF incidence, age, and sex emphasizes the need for age- and sex-specific strategies in AF prevention and management. The observed relationship between comorbidity burden and AF incidence suggests differential effectiveness of cardiovascular risk management across patient subgroups.

Further findings
Standardized IR (SIR) · 2000 to 2021
- SIR decreased from
- 170.62 per 100,000 person-years
- SIR decreased to
- 112.38 per 100,000 person-years
Incidence rates (IRs) by sex
- Male patients demonstrated higher IRs than female patients across all age groups
IRs by age
- The annual IRs substantially increased with age
Trend in IRs
- IRs exhibited a declining trend, except in men aged 20-49 years and women aged 20-34 years
SIR trends by comorbidity burden
- Individuals with lower comorbidity burden demonstrated lower SIRs and earlier declines in SIRs
