Coronary Artery Disease (CAD) Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Small vessel disease is a condition in which the walls of the small arteries in the heart aren't working properly. Plaque buildup causes the inside of the arteries to narrow over time. Nonobstructive coronary artery disease (CAD) is atherosclerotic plaque that would not be expected to obstruct blood flow or result in anginal symptoms (such as chest pain).
