Key result
Female sex is linked to a ~30% lower prevalence of major ECG abnormalities than males.
Why the study?
Sex differences in the occurrence of major ECG abnormalities have been poorly studied, particularly across different ethnic groups.
Do sex differences in the prevalence of major ECG abnormalities vary across ethnic groups in adults without cardiovascular disease?
Population
8089 men and 11 369 women aged 18-70 years without CVD across six ethnic groups in Amsterdam
Comparison
Women vs men across ethnic groups and age-groups
Design
Cross-sectional analysis of a population-based study

Sex differences in major ECG abnormalities attenuated in ethnic minorities; leaves open whether ethnicity-specific ECG norms are needed.
Cross-Sectional (n=19,458)
Do sex differences in the prevalence of major ECG abnormalities vary across ethnic groups in adults without cardiovascular disease?
Absolute Event Rate: 4.6% vs 6.6%
The lower prevalence of major ECG abnormalities typically seen in women compared to men is less apparent in ethnic minority groups, particularly among South-Asian Surinamese individuals, independent of conventional cardiovascular risk factors.
Bolijn et al. (2020) conducted a cross-sectional in Without cardiovascular disease (n=19,458). Female sex vs. Male sex was evaluated on Prevalence of major ECG abnormalities. Female sex was associated with a lower prevalence of major ECG abnormalities compared to male sex (4.6% vs 6.6%), though this difference was attenuated in ethnic minority groups.
