Two types of operation are used in the treatment of coronary heart disease (CHD) to improve the flow of blood to the heart. These are Coronary Artery Bypass Grafts (CABG) and angioplasties.

A CABG involves grafting a blood vessel from another part of the body to the coronary arteries to bypass narrowed sections and restore blood flow to the muscle. An angioplasty involves passing a thin hollow tube into the coronary arteries from an artery in the groin or arm. A device on the tube unblocks the artery and stretches the artery walls to allow blood to flow to the heart muscle. An angioplasty is generally regarded as a less major procedure than a CABG.

Coronary angiography is carried out to diagnose CHD by an x-ray study of the heart blood vessels to confirm whether the arteries are blocked or diseased. It can also be used as part of the treatment. The angiography activity is split into diagnostic angiographies (angiography with no associated angioplasty) and diagnostic angiographies used to assist in treatment (angiographies done in association with angioplasty).
