Key result
South Asian male athletes show larger LV dimensions than controls but smaller dimensions than Afro-Caribbean athletes.
Why the study?
There is a conspicuous lack of data on cardiac adaptation in South Asian athletes, limiting understanding of ethnicity-specific cardiovascular screening.
Population
100 male South Asian competitive athletes aged 14–35
Comparison
South Asian athletes vs Caucasian and Afro-Caribbean athletes and South Asian controls
Design
Cross-sectional study with pre-participation ECG and echocardiography

May support ESC criteria use in South Asian athletes; extends ethnic comparisons but leaves open prospective validation.
Cross-Sectional (n=250)
p-value: p=<0.05
South Asian male athletes exhibit similar ECG changes and upper limits of cardiac dimensions to Caucasians, suggesting that ESC criteria for ECG interpretation are applicable to this demographic.
Ghani et al. (2013) conducted a cross-sectional in Cardiovascular adaptation in athletes (n=250). Competitive sports training in South Asian athletes vs. Caucasian athletes, Afro-Caribbean athletes, and South Asian controls was evaluated on ECG changes and echocardiographic characteristics including cardiac chamber size and wall thickness (p=<0.05). South Asian male athletes had larger LV dimensions than controls (p<0.05), but smaller dimensions and fewer ECG anomalies than Afro-Caribbean athletes (p<0.05).
