What is Coronary Heart Disease?
The circulatory system is made up of the heart and blood vessels. Blood vessels that return blood back to the heart are called veins. Vessels that carry blood away from the heart are called arteries. Arteries that supply blood to the heart are called coronary arteries. If these coronary arteries that carry oxygen and nutrients to the heart become obstructed, the flow of blood is cut off preventing the heart from getting the oxygen and nourishment it needs. The two most common causes of obstruction are arteriosclerosis, or hardening of the arteries or the presence of a thrombus, or blood clot. Either of these conditions can cause Coronary Heart Disease.
