Table 2 Key consideration points regarding ethnicity for preparticipation screening

There is a greater prevalence of concentric LVH in BAs compared to WAs, Asians, Arabic, Pacific Islanders, and mixed ethnicity

MEAs have phenotypical similarities to BAs although less pronounced and have a greater LVWT than WAs

BAs who have a RWT of up to 0.51 in males and 0.48 in females may be physiological although this should be interpreted with caution in the presence of symptoms or a family history of SCD

RV structural adaptation is similar in BAs, WAs and MEAs

BAs appear to have larger LA dimensions than WAs but this needs to be reproduced in future studies and until then the existing normal ranges should be applied
