Key result

Black African male athletes demonstrated a significantly higher prevalence of 'uncommon' ECG changes compared to West-Asian and Caucasian athletes (P<0.001).

Why the study?

Does ethnicity affect the prevalence of 'uncommon' ECG abnormalities in male athletes?

Key Points

This study aims to evaluate the electrocardiographic characteristics of male athletes from different ethnic backgrounds.
Cardiovascular screening was conducted with resting 12-lead ECG analysis of 1220 national level athletes, divided by ethnicity: 800 West-Asian, 300 black, and 120 Caucasian.
135 West-Asian controls were also included in the analysis.
10% of athletes showed 'uncommon' ECG findings, with black African descent being a significant predictor (p<0.001).
Black athletes had a higher prevalence of lateral T-wave inversions compared to West-Asian and Caucasian athletes (6.1% vs 1.6% and 0%, p<0.05).
0.6% of athletes had diseases associated with sudden death, more prevalent in black athletes (1% vs 0.5% for West-Asian).

Does ethnicity affect the prevalence of 'uncommon' ECG abnormalities in male athletes?

Population

1,355 male national level athletes and controls in Qatar undergoing cardiovascular screening with resting 12-lead ECG.

Exposure

Resting 12-lead ECG analysis using the 2010 recommendations for 12-lead ECG interpretation by the European Society of Cardiology (ESC).

Comparator

Comparison between different ethnicities (West-Asian, black, and Caucasian) and non-athlete West-Asian controls.

Outcome

Prevalence of 'uncommon' ECG findings.surrogate

Main Result

p-value: p=<0.001

Black male athletes demonstrate a significantly higher prevalence of 'uncommon' ECG findings and lateral T-wave inversions compared to West-Asian and Caucasian athletes, emphasizing the need to account for ethnicity in sports cardiology screening.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Ethnicity may influence ECG screening interpretation in male athletes; leaves open need for prospective outcome validation.

Wilson et al. (2011) conducted a cross-sectional in National level athletes (n=1,355). Black African ethnicity vs. West-Asian and Caucasian ethnicity was evaluated on 'uncommon' ECG changes (p=<0.001). Black African male athletes demonstrated a significantly higher prevalence of 'uncommon' ECG changes compared to West-Asian and Caucasian athletes (P<0.001).
