Athletic Training Practice Exam

Which of the following statements is true about hypertrophic cardiomyopathy (HCM)?

1. Incidence of sudden death from HCM is 2 to 3 times higher in children and adolescents than in adults

2. Incidence of sudden death from HCM is 2 to 3 times higher in adults than in teenagers

3. The incidence of sudden death from HCM is 4 to 6 times higher in black males than in white males

4. Incidence of sudden death from HCM is 4 to 6 times higher in females than males

The correct answer is: Incidence of sudden death from HCM is 2 to 3 times higher in children and adolescents than in adults

The statement that the incidence of sudden death from hypertrophic cardiomyopathy (HCM) is 2 to 3 times higher in children and adolescents than in adults is correct. HCM is a genetic condition that often presents in young athletes, leading to unexpected cardiac events during sports or exercise. Studies have indicated that the risk of sudden cardiac death associated with HCM is indeed greater in younger populations, particularly in those who engage in competitive sports. This higher risk can be attributed to factors such as the anatomical and physiological differences in younger individuals and the often undiagnosed nature of the condition in this age group. In contrast to children and adolescents, adults generally have more established cardiovascular screening practices, potentially reducing the likelihood of undiagnosed HCM and its associated risks. This distinction underlines the importance of rigorous cardiovascular evaluations for young athletes, especially in populations at heightened risk, to implement necessary preventative measures.
