title: Percutaneous coronary intervention for stable coronary artery disease.
abstract: Patients with significant coronary artery stenoses are at increased risk of future cardiac events. However, in the absence of acute coronary syndrome or recent myocardial infarction and residual ischemia, elective percutaneous coronary intervention has not been shown to improve prognosis. Possible explanations for this might be the limited follow-up time adopted by most randomized trials comparing percutaneous coronary intervention with medical therapy, limited number of patients with proven ischemia enrolled in these trials, and adoption of complex, elaborate techniques that have not proved their usefulness. Published evidence identifies certain indications for percutaneous coronary intervention in patients with stable coronary lesions: demonstration of significant inducible ischemia, particularly in the context of a recent myocardial infarction; detection of unequivocally reduced fractional flow reserve; and specific angiographic features of coronary stenoses. Operators should take into account long-term consequences of adopted techniques rather than immediate angiographic results. We review existing evidence and provide our recommendations in this setting.
