Etiologies of SCA by country in a young athlete population. Comparison of the most common etiologies of SCA in different regions. The data shows that AN‐SUD was the most common cause of SCA in the United Kingdom (mean age 29), while HCM was the most common in the United States (mean age 17). In Italy (mean age 23), ARVC was found to be the most common etiology. This figure highlights the regional differences in the causes of SCA and the importance of understanding the specific etiologies in different populations to improve SCA prevention and management.
