Hypertrophic cardiomyopathy is a condition in which the muscle of the heart's left ventricle becomes thicker than normal, making it hard are for blood to leave the heart and get to the rest of the body. Hypertrophic cardiomyopathy forces the heart to work harder to pump blood, and may also affect the hearts mitral valve, causing blood to leak backward through the valve.
Hypertrophic cardiomyopathy is a rare condition that is usually passed down through families, and may be found in people of all ages.
Symptoms of hypertrophic cardiomyopathy
Some patients with hypertrophic cardiomyopathy experience no symptoms – they may be unaware they have the condition until it is discovered during a medical exam. For some younger patients, the first symptom of hypertrophic cardiomyopathy may be sudden collapse and possible death, caused by an extremely abnormal heart rhythm or the blockage of blood flow from the heart to other organs.
Other common symptoms include:
- Chest pain
- Dizziness or lightheadedness, especially during physical activity
- Fainting, especially during exercise
- Fatigue
- Shortness of breath during physical activity or after lying down or being asleep for a period of time
- Heart palpitations – a sensation of strongly feeling the heart beating
