Current Indications for Stenting: Symptoms or SurvivalCME

The major goals of treating ischemic heart disease are to reduce angina, improve quality of life, and ultimately reduce mortality. While medical therapy can effectively address these aims, there is still much research and debate about the role of percutaneous coronary intervention in the treatment spectrum-specifically, whether or not stenting prolongs life or simply treats symptoms without impacting survival. The data supporting revascularization for survival benefit came from patients who underwent bypass graft surgery prior to the introduction of effective medical management. Although both physicians and patients continue to believe in the life-saving ability of coronary stenting, little data exist to support this belief outside of when used during an acute myocardial infarction. Strategy trials designed to test the benefit of coronary stenting have limitations that have curbed physicians' willingness to accept the results, but they provide the best evidence for how to optimally manage these patients. In this article, we explore the data supporting the use of coronary stenting for various indications and the questions that remain to be answered.
