On March 10, the ACC and other medical societies updated the terminology used in the appropriate use criteria (AUC) for coronary revascularization in patients with stable ischemic heart disease. Gregory Dehmer, MD, notes the old methodology used “appropriate,” “uncertain” and “inappropriate,” whereas the new methodology uses “appropriate,” “may be appropriate” and “rarely appropriate.” Dehmer says the new terminology is a better fit for how cardiologists practice and discusses other changes in the updated AUC.
