Heart disease

From Free net encyclopedia

Heart disease is one of a number of different diseases which afflict the heart. The most common heart diseases are:

• Coronary heart disease, the end result of the accumulation of atheromatous plaques within the walls of the arteries that supply the myocardium
• Ischaemic heart disease, a disease characterized by reduced blood supply to the heart.
• Cardiovascular disease, a class of diseases that involve the heart and/or blood vessels (arteries and veins).
• Pulmonary heart disease, a failure of the right side of the heart.

The study of the heart, and of diseases of the heart, is cardiology.
