What Is Coronary Heart Disease? - NHLBI, NIH Coronary heart disease is a type of heart disease that occurs when the arteries of the heart cannot deliver enough oxygen -rich blood to the heart muscle due to narrowing from the buildup of fatty deposits called plaque It is also sometimes called coronary artery disease or ischemic heart disease
