A coronary occlusion, or coronary artery disease, is the partial or complete obstruction of blood flow in a coronary artery. This condition was first discussed in 1910 by Sir William Osler. This condition slows or blocks the supply of oxygen-rich blood to the heart. This condition can lead to myocardial ischemia and if untreated, may cause a heart attack and heart failure. It is the most common form of cardiovascular disease, and is the leading cause of death in the United States, affecting 18 million adults.
