Firstly, for approximately one third of low risk patients the principal reason for performing coronary artery bypass procedures is for the relief of angina, rather than mortality prevention.2 Secondly, people on waiting lists inevitably have widespread vascular disease and the atherosclerotic lesions that cause sudden death may not be the same as those for which the patient has been listed for relief of angina.3 Lastly, operative death rates for elective surgery of 1%2%4 mean a proportion of patients die as a result of the procedure itself.
