Abstract
Treatments are designed to make people feel better or live longer. Percutaneous coronary intervention (PCI) is effective at reducing angina in patients with symptomatic coronary artery disease and at reducing mortality in patients who have acute myocardial infarction with ST-segment elevation and in those who have high-risk acute coronary syndromes without ST-segment elevation.1 Such successes have often been extrapolated in support of more widespread use of PCI in patients with stable coronary artery disease in hopes of reducing subsequent cardiac events.With the increasing availability of noninvasive imaging of coronary artery disease, asymptomatic patients are often referred for PCI.
