Hypertrophic Cardiomyopathy (HCM)
What Is HCM?
Hypertrophic cardiomyopathy (HCM) is a condition in which the heart muscle becomes abnormally thick. This can make it harder for the heart to pump blood effectively.
HCM is one of the most common causes of sudden cardiac arrest in young athletes.
Why HCM Matters
Many individuals with HCM have no symptoms. For some, the first sign of the condition may be collapse during physical activity.
Possible Warning Signs
What Parents & Schools Should Know
Preparedness Is Protection
Even with screening, emergencies can happen. AED access and CPR training are essential safeguards.
