Coronary Heart Disease is the most common form of heart disease. It occurs when the arteries supplying blood to the heart narrow or harden from the build-up of plaque. Plaque is made up of fat, cholesterol and other substances found in the blood. This plaque build-up is also known as atherosclerosis.
There are many different types of diseases that can affect the heart and vascular system. Such as Coronary Artery Disease, Heart Attack, Arrhythmia, Heart Failure, Congenital Heart Defects, Cardiomyopathy, Peripheral Artery Disease.
