When Coronary Stents are ‘Inappropriate’

The correct use of coronary stents in elective cases − patients who aren’t having a heart attack or suffering from other acute syndromes − remains a subject of disagreement among cardiologists. In a 2011 study, about half the procedures used to implant elective stents were considered “appropriate” while 12 percent were “inappropriate” and 38 percent were “uncertain” under guidelines of the American College of Cardiology that are under revision. The study examined 144,737 elective Percutaneous Coronary Interventions, or PCIs. More than 90 percent of PCIs result in stents.
