Heart disease

Definition:

Heart disease is any disorder that affects the heart's ability to function normally. The most common cause of heart disease is narrowing or blockage of the coronary arteries, which supply blood to the heart itself. This happens slowly over time. (See coronary artery disease.)

Some heart diseases can be present at birth (congenital heart diseases).
