Coronary heart disease is also known as Coronary Artery Disease, Coronary Microvascular Disease, Coronary Syndrome X, Ischemic Heart Disease, Nonobstructive Coronary Artery Disease, Obstructive Coronary Artery Disease.

Coronary heart disease is sometimes called ischemic heart disease or coronary artery disease. It develops when major blood vessels that supply the heart become damaged or diseased.

In normal physiological conditions, the coronary arteries supply the myocardium with blood, oxygen, and nutrients. Though, these arteries can be narrowed by arteriosclerotic plaque,  decreasing blood flow to your heart. Eventually, the reduced blood flow may cause chest pain (angina), shortness of breath, or other coronary artery disease signs and symptoms. A complete blockage can cause a heart attack.

Because coronary artery disease often develops over decades, you might not notice a problem until you have a significant blockage or a heart attack. But you can take steps to prevent and treat coronary artery disease. A healthy lifestyle can make a big impact.
