Ischemic Heart Disease (National Heart, Lung, and Blood institute)

Heart disease is a catch-all phrase for a variety of conditions that affect the heart’s structure and function. Ischemic heart disease occurs when the arteries of the heart cannot deliver enough oxygen-rich blood to the heart. It is the leading cause of death in the United States, with most deaths occurring from coronary heart disease, also known as coronary artery disease—the most common type of ischemic heart disease.
