Correction: Health Status and Angina Relief Results from COURAGE

In our summary Health Status and Angina Relief Results from COURAGE, published online on August 13, 2008, we incorrectly described an initial treatment strategy of percutaneous coronary intervention for patients with stable coronary artery disease as “primary PCI.” We have corrected this error in our original summary, and the final sentence now reads (changed text indicated in bold), “Although the trial was conducted before drug-eluting stents came into widespread use, its results suggest that elective PCI should be reserved for patients with the most severe symptoms.”

We apologize for the error.
