Can you tell me the description of heart disease.?

heart disease
n.
A structural or functional abnormality of the heart, or of the blood vessels supplying the heart, that impairs its normal functioning.

When you think of heart disease, usually people think of coronary artery disease (narrowing of the arteries leading to the heart), but coronary artery disease is just one type of cardiovascular disease.

Cardiovascular disease includes a number of conditions affecting the structures or function of the heart. They can include:

Coronary artery disease (including heart attack)
Abnormal heart rhythms or arrythmias
Heart failure
Heart valve disease
Congenital heart disease
Heart muscle disease (cardiomyopathy)
Pericardial disease
Aorta disease and Marfan syndrome
Vascular disease (blood vessel disease)
Cardiovascular disease is the leading cause of death for both men and women in the U.S. It is important to learn about your heart to help prevent heart disease. And, if you have cardiovascular disease, you can live a healthier, more active life by learning about your disease and treatments and by becoming an active participant in your care.
