This is an exciting and important method of ascertaining and ensuring patient education with regard to their perceived outcomes of PCI. The writing committee did not support including this as a measure because the out- comes of PCI vary according to presenting symptoms; for example, patients with an acute myocardial infarction could have an improved risk of mortality as a result of their PCI, but patients undergoing elective PCI for chronic stable angina probably have no improvement in their outcome other than symptom relief.
