Percutaneous coronary interventions (PCI) have become standard treatment for many patients with coronary artery disease (CAD). It is therefore important that general practitioners know what the indications, limitations, complications and expectations of the procedure are in order to advise their patients. This is the 3^rd article in a series of articles on coronary artery disease. The first article defined the acute coronary syndromes clinically and the second article discussed post-MI care by the GP. The next article will be on Coronary Artery Bypass Graft (CABG) surgery.
