Yes "stable" is key, worth researching if a stent is recommended.
Optimal Medical Therapy with or without PCI for Stable Coronary Disease by William Boden in the April 12, 2007 issue of the New England Journal of Medicine found after studying 2287 patients, “As an initial management strategy in patients with stable coronary artery disease, PCI (angioplasty) did not reduce the risk of death, myocardial infarction, or other major cardiovascular events when added to optimal medical therapy.”1 In 2004, more than 1 million coronary stent procedures were performed in the United States, and recent registry data indicate that approximately 85% of all PCI procedures are undertaken electively in patients with stable coronary artery disease.
