    Causes, incidence, and risk factors

    The most common cause of heart disease is a narrowing of or blockage in the coronary arteries supplying blood to the heart muscle (coronary artery disease). Some heart diseases are present at birth (congenital heart disease).

    Other causes include:

    • Abnormal heart rhythm
    • Abnormal heart valve function
    • High blood pressure (hypertension)
    • Cardiomyopathy - weakening of the heart's pumping ability, often caused by heart disease, viral infection, or toxins
