IT IS A DISEASE OF: Your heart musclein which a part of the heart muscle is thickened or hypertrophied without any obvious cause. It is better known for causing silent, sudden cardiac death in otherwise healthy young people and athletes. Younger people are likely to have a more severe form of hcm. It is frequently free of symptoms until sudden cardiac death, and for this reason some suggest screening these youngsters.

HCM: Hypertrophic cardiomyopathy is a condition in which the heart muscle becomes thick, and obstruction to outflow may occur. Arrhythmias may occur as well. It is commonly inherited, first degree relatives should be screened. Patients may have severe symptoms, or no symptoms at all. It is a common cause of death in young athletes who seemed completely healthy.

Complete evaluation: Hypertrophic cardiomyopathy is potentially dangerous, but very manageable. A complete assessment by a physician who is well versed in the condition is very important. Until that evaluation occurs, you should avoid overly stressful activities such as competitive sports. Symptoms of palpitations, dizziness or fainting warrant a more urgent assessment.

A 35-year-old member asked:

Can you describe hypertrophic cardiomyopathy?

2 doctor answers5 doctors weighed in
Dr. Mark Milunski
Cardiology 37 years experience
HCM: Hcm is an abnormal thickening usually of the wall (septum) that divides the right and left ventricle. This thickening occurs in the absence of other diseases known to cause thickening of the heart muscle. It is relatively uncommon but occurs in a familial/hereditary form more than 50% of the time. Therefore, siblings and children of patients with hcm should be screened for it.

What is hypertrophic cardiomyopathy (hcm)?

Dr. James Chen
Sports Medicine 15 years experience
HCM: Hypertrophic cardiomyopathy is a rare condition of the actual muscle of the heart becoming so large and thick as to obstruct outgoing blood flow. Because outgoing flow is reduced the heart must work even harder to pump blood to supply oxygen to the body. It is notable because patients are usually asymptomatic but can initially present with sudden collapse or even death.

Preventable: Hcm is caused by one of 20 genetic mutations. Some are mild and may take a long time to be recognized. Others are malignant and lead to fatal arrhythmia early on. People performing strenous cativity(athletes) may be particularly at risk. If there are risk factors such as family history, you should be evalated by a qualified cardiologist. Once diagnosed, sudden death can usually be prevented.
