Leading Interventional Cardiologist Dr David Brull explains: "Obstructive coronary artery disease occurs when the arteries that supply blood to the heart become clogged with fatty deposits so that insufficient levels of oxygen can reach the heart muscle. If this occurs slowly it causes angina, however, sometimes it can occur suddenly if a blood clot completely blocks the arteries and this then leads to a heart attack."
