Coronary Heart Disease, also called Coronary Artery Disease, is characterized by the disruption in the flow of oxygen and nutrients to the heart from the thickening or narrowing of the coronary arteries.

It can be prevented by maintaining a healthy lifestyle like by keeping a healthy diet, not smoking, staying active, etc. Once acquired, current treatments available for CAD include certain medications, lifestyle changes, and surgical procedures to open the blood vessels.
