Treatment of coronary artery disease starts with managing risk factors such as reducing cholesterol, controlling blood pressure, managing diabetes when present, achieving ideal weight, getting more exercise and quitting smoking.
The following may also be used:
Drug therapy, which can reduce or get rid of the risk of angina and heart attack.
Coronary artery bypass surgery. Veins taken from another part of the body are used to reroute blood around a blocked area.
Angioplasty. A long wire is threaded from the groin to the blocked area of the heart. A balloon attached to a catherter at the tip of the wire is inflated to clear and widen the clogged artery. In some cases, a stent (metal or plastic tube) is placed in the artery to make sure it stays open.
Brachytherapy. By applying radiation to the affected artery, arteries are prevented from narrowing again, which can happen even after a stent (a tube-like device) has been put in to help keep the artery open.
