Hypertrophic cardiomyopathy (HCM) is a genetic heart disorder marked by abnormal thickening of the heart muscle, increasing the risk of heart failure and sudden cardiac death, especially in young people. This thickening occurs due to a genetic mutation and is not caused by high blood pressure or valve disease.
The abnormal growth can lead to:
-
Impeded blood flow from the heart
-
Dangerous heart rhythm disturbances
-
Progressive heart failure
-
Increased risk of sudden cardiac death
Approximately 50% of cases are inherited, making early screening and genetic counseling crucial to detect the condition before complications arise.
Symptoms of HCM:
-
Shortness of breath
-
Chest pain or pressure
-
Palpitations and rapid heartbeat
-
Dizziness and nausea
-
Fainting episodes
Many people may feel normal at rest, but symptoms often appear during physical activity. Sudden collapse during exercise can be the first sign, particularly in younger individuals.
Why Early Detection Matters:
Awareness of family history, noticing unexplained fainting, and abnormal ECG results, along with consulting a specialist, can help prevent serious complications.
