Obstructive hypertrophic cardiomyopathy (HCM) is a genetic heart condition where the heart muscle grows abnormally thick, particularly affecting the left ventricle and the septum between the heart chambers. This thickening occurs because heart muscle fibers grow in a disorganized pattern, making the heart muscle stiffer than normal.

The "obstructive" part refers specifically to how the thickened septum blocks blood flow into the aorta - the main artery that carries blood from the heart to the rest of the body. Common symptoms include:
• Shortness of breath
• Dizziness
• Heart palpitations
• Chest pain
• Fainting
• Irregular heartbeat
• Heart failure symptoms

These symptoms often become more noticeable during physical activity. Some people with mild HCM may not experience any symptoms at all. This condition affects approximately 1 in 500 people in the United States, making it the most common inherited heart disease. If you have a parent with HCM, you have a 50 percent chance of inheriting the condition. Regular monitoring by healthcare professionals who specialize in HCM is essential for managing the condition effectively.
