At this point there are many procedures available to treat CAD all of which aim to improve myocardial blood flow, stop angina, increase exercise ability and ultimately free patients from medications and improve their quality of life. Medications are used to reduce blood pressure and relieve strain on the heart. Cardiologists use angioplasty, which compresses plaque deposits, and stenting, in which a small wire mesh tube is inserted into the diseased artery to revascularize the heart muscle. On-pump coronary artery bypass grafting (CABG) redirects blood flow around clogged vessels of the heart and is commonly used by cardiac surgeons to treat CAD because it has been proven to yield the lowest restenosis rate of all revascularization techniques (Cisowski, 2002). CABG is an effective yet painful and traumatic intervention.
