HCM is usually most severe when it occurs in younger people, but it can occur at any age.
Other factors that may increase your chances of HCM include:
Having a family member with HCM
Being over age 60 and having hypertension
Fainting, particularly during exercise
Lightheadedness, particularly following exercise
Shortness of breath or difficulty breathing
Tiring easily during exercise or activity
Shortness of breath when lying down
These symptoms can be caused by some of the side effects of the condition, including heart
arrhythmias. The blocked or reduced blood flow is usually the cause of symptoms like lightheadedness, fainting, and difficulty breathing.
The doctor will ask about symptoms and past health. A physical exam will be done.
Electrical activity of the heart may need to be tracked. This can be done with an
ECG that can be worn all day.
Many people with HCM live a normal, healthy life with few symptoms. However, HCM does increase the risk of sudden death.
Treatment focuses on managing symptoms and preventing problems. Treatment may include:
Medicines may be used to help the heart work better. These may include:
Beta-blockers and calcium channel blockers
Surgery may be needed to remove thickened part of the heart muscle. It may be done if the muscle is blocking too much blood flow from the heart.
Surgery may also be done to repair or replace the mitral valve if it is leaking.
Alcohol Septal Ablation
Alcohol is injected into the blood vessels that feed the enlarged heart. It will make part of the tissue shrink back. This should decrease blockage in the heart and improve blood flow out of the heart.
Implantable Cardioverter Defibrillators (ICD)
can help to control abnormal heart rhythms. It send an electrical impulse automatically when needed. It may be done if there is an increased risk for sudden death.
Some chronic heart issues or medical conditions increase the risk of HCM. Following the care plan may help to decrease the risk of HCM developing.
