What is Heart Disease?

Heart disease is one of several cardiovascular diseases, which are diseases of the heart and blood vessel system. The main form of heart disease is coronary heart disease, which is a disorder of the blood vessels of the heart that can lead to heart attack. A heart attack happens when an artery becomes blocked, preventing oxygen and nutrients from getting to the heart.[1]
