2011 ACCF/AHA/SCAI Guideline for Percutaneous Coronary Intervention

The medical profession should play a central role in evaluating the evidence related to drugs, devices, and procedures for the detection, management, and prevention of disease. When properly applied, expert analysis of available data on the benefits and risks of these therapies and procedures can

Radial Artery Bypass Grafts Have an Increased Occurrence of Angiographically Severe Stenosis and Occlusion Compared With Left Internal Mammary Arteries and Saphenous Vein Grafts

Background—The radial artery has been increasingly used in CABG. However, angiographic outcome data have been limited. Methods and Results—We reviewed all coronary angiography procedures from February 1996 to October 2001 and selected patients with a radial artery bypass graft. Angiographic outcomes were divided into groups as (1) occluded, (2) severe disease (≥70% stenosis, or string sign), or (3) patent (<70% stenosis). Multivariable analyses determined predictors of severe disease or occlusion. A total of 310 patients had a radial artery graft. Mean follow-up after coronary artery bypass grafting was 565 ± 511 days. Radial artery grafts had a patency rate of 51.3%, which was significantly lower than that for left internal mammary arteries (90.3%, P < 0.0001) or saphenous vein grafts (64.0%, P = 0.0016). Radial artery grafts had an occlusion rate of 33.7%, compared with 4.8% for left internal mammary arteries (P < 0.0001), and had a severe stenosis rate of 15.1%, compared with 5.9% for saphenous vein grafts (P = 0.0003) and 4.8% for left internal mammary arteries (P < 0.0001). Women had a worse overall radial artery patency rate than men (38.9% versus 56.1%, P = 0.025). A radial artery graft was the most powerful multivariable predictor of severe stenosis or occlusion (χ2 = 28.87, P < 0.0001). Because of diseased radial artery grafts, 58 patients required subsequent percutaneous intervention, and 26 patients required repeat CABG. Conclusions—In patients predominantly presenting with signs and symptoms of myocardial ischemia after CABG, radial artery grafts have lower patency rates than left internal mammary artery and saphenous vein grafts. Selective use of the radial artery is warranted, particularly in women.

To ensure that guidelines reflect current knowledge, available treatment options, and optimum medical care, existing clinical practice guideline recommendations are modified and new recommendations are added in response to new data, medications or devices. To keep pace with evolving evidence, the American College of Cardiology (ACC)/American Heart Association (AHA) Task Force on Clinical Practice Guidelines (“Task Force”) has issued this focused update to revise guideline recommendations on the basis of recently published data. This update is not based on a complete literature review from the date of previous guideline publications, but it has been subject to rigorous, multilevel review and approval, similar to the full guidelines. For specific focused update criteria and additional methodological details, please see the ACC/AHA guideline methodology manual.1 ### Modernization In response to published reports from the Institute of Medicine2,3 and ACC/AHA mandates,4–7 processes have changed leading to adoption of a “knowledge byte” format. This entails delineation of recommendations addressing specific clinical questions, followed by concise text, with hyperlinks to supportive evidence. This approach better accommodates time constraints on busy clinicians, facilitates easier access to recommendations via electronic search engines and other evolving technology (eg, smart phone apps), and supports the evolution of guidelines as “living documents” that can be …

Emergency Department Physician Activation of the Catheterization Laboratory and Immediate Transfer to an Immediately Available Catheterization Laboratory Reduce Door-to-Balloon Time in ST-Elevation Myocardial Infarction

Background— Consensus guidelines and hospital quality-of-care programs recommend that ST-elevation myocardial infarction patients achieve a door-to-balloon time of ≤90 minutes. However, there are limited prospective data on specific measures to significantly reduce door-to-balloon time. Methods and Results— We prospectively determined the impact on median door-to-balloon time of a protocol mandating (1) emergency department physician activation of the catheterization laboratory and (2) immediate transfer of the patient to an immediately available catheterization laboratory by an in-house transfer team consisting of an emergency department nurse, a critical care unit nurse, and a chest pain unit nurse. We collected door-to-balloon time for 60 consecutive ST-elevation myocardial infarction patients undergoing emergency percutaneous intervention within 24 hours of presentation from October 1, 2004, through August 31, 2005, and compared this group with 86 consecutive ST-elevation myocardial infarction patients from September 1, 2005, through June 26, 2006, after protocol implementation. Median door-to-balloon time decreased overall (113.5 versus 75.5 minutes; P<0.0001), during regular hours (83.5 versus 64.5 minutes; P=0.005), during off-hours (123.5 versus 77.5 minutes; P<0.0001), and with transfer from an outside affiliated emergency department (147 versus 85 minutes; P=0.0006). Treatment within 90 minutes increased from 28% to 71% (P<0.0001). Mean infarct size decreased (peak creatinine kinase, 2623±3329 versus 1517±1556 IU/L; P=0.0089), as did hospital length of stay (5±7 versus 3±2 days; P=0.0097) and total hospital costs per admission (
