Introduction
Coronary artery disease (CAD) is the major cause of death in developed countries.1 It may present as a typical `heart attack', as sudden death, or it may be detected at a later date and be described as a silent infarct. Good coronary care units, the use of thrombolytic and anti-arrhythmic drugs, and accurate methods for assessing cardiac function and coronary artery pathology have all successfully reduced in-hospital mortality. However, about 75% of those who have a myocardial infarction (MI) die outside hospital,2 and sudden death is the first and only manifestation in about 20% of all those who present with CAD.3,4 Therefore, treatment is not available for most patients, and the aim must be to prevent the development and progression of CAD.
There are five conditions that predispose to premature death from CAD. These are: hypertension;5,6 hypercholesterolaemia;7,8 the post-menopausal state;9,10 a thrombotic tendency;11,12 and the risk of developing ventricular arrhythmias.13
