Exercise testing? Not at all.
The traditional approach to the ambulatory patient with suspected or definite coronary disease is to evaluate the clinical features, to perform non-invasive tests for myocardial ischaemia, and to proceed, if necessary, to coronary angiography and coronary revascularisation. However, when the results of the exercise tests are discordant with the clinical classifications they are usually misleading as diagnostic tools. When the exercise test is used to assist prognostication, the information provided overlaps with that available to the clinician and only the presence of ST segment depression is an independent prognosticator. The amount of ST segment shift has been found to be an inferior prognosticator to the severity of disease seen on a coronary angiogram and the latter allows for appropriate decisions to be made regarding coronary angioplasty or bypass surgery. A more appropriate use of exercise testing is as a gate for coronary angiography if there is real doubt or the nature of the chest pain or as an aid in therapeutic decisions if the coronary angiography interpretation is difficult.
