Hypertrophic cardiomyopathy is a heart condition that is characterized by inappropriate thickening of the heart muscle which may occur throughout the heart or more frequently in the interventricular septum, which is the heart muscle that separates the ventricles (the two lower chambers of the heart). This condition results in abnormalities in the heart's ability to relax, which allows blood to enter the heart, and to contract (squeeze), which allows the heart to pump blood to the body.
Hypertrophic cardiomyopathy is the thickening of the muscles that make up the heart.

Symptoms and Tests
Those who have hypertrophic cardiomyopathy may have no symptoms or only
mild symptoms. The most common symptom is difficulty breathing.
Fatigue, feeling as if one is about to pass out (pre syncope), and
actually passing out (syncope)
are also common symptoms. Unfortunately, sometimes, the first
manifestation of hypertrophic cardiomyopathy is sudden death. A medical
evaluation to determine if a patient has hypertropic cardiomyopathy
includes a variety of diagnostic tests such as an electrocardiogram, echocardiogram, Holter monitoring, treadmill or bicycle exercise testing, and cardiac catheterization. These tests and other tests may be recommended to better evaluate this disease.
Treatments
Treatment for hypertrophic cardiomyopathy focuses on alleviating
symptoms, preventing complications and reducing the risk of death. Most
patients with hypertrophic cardiomyopathy can be treated medically.
Medications, such as beta blockers and calcium channel blockers, are
often prescribed to reduce symptoms. An implantable cardiac
defibrillator may be recommended if the risk of sudden death is high.
In a small number of patients, symptoms are not well managed with
medical therapy, and surgery may be recommended.
