The following are highlights from the new series, Circulation: Cardiovascular Quality and Outcomes Topic Review. This series will summarize the most important manuscripts, as selected by the editors, that have published in the Circulation portfolio. The objective of this new series is to provide our readership with a timely, comprehensive selection of important papers that are relevant to the quality and outcomes and general cardiology audience. The studies included in this article represent the most significant research in the area of ST-segment elevation myocardial infarction care and address improvements in the timeliness of care, strategies for initial treatment-particularly with respect to reperfusion therapies-and trends. (Circ Cardiovasc Qual Outcomes. 2012;5:e1-e8.) Temporal Conclusions: The rapid changes in practice patterns demonstrated in this analysis suggest that a collaborative partnership between the public media, professional societies, and academic organizations is needed to accurately distill and disseminate pivotal scientific information that has the potential to rapidly influence both physicians and patients. 1
Sustaining Improvement in Door-to-Balloon Time Over 4 Years: The Mayo Clinic ST-Elevation Myocardial Infarction ProtocolSummary: American College of Cardiology/American Heart Association guidelines recommend a door-to-balloon time (DTB) Ͻ90 minutes for nontransferred patients with ST-elevation myocardial infarction (STEMI) who undergo primary percutaneous coronary intervention. Systems of care to achieve and sustain this DTB performance over several years have not been previously reported. The Mayo Clinic STEMI protocol was implemented in April 2004 and included activation of the cardiac catheterization laboratory by the emergency medicine physician; a single call system to activate the catheterization laboratory; catheterization laboratory staff arrival within 20 -30 minutes of activation; and real-time performance feedback within 24 -48 hours. Data were collected on nontransferred STEMI patients.
Conclusions:The Mayo Clinic STEMI protocol implemented strategies to reduce DTB for nontransferred patients with STEMI. DTB was significantly reduced, and the results were sustained over the 4-year follow-up period. The authors' experience demonstrates the effectiveness and durability of process changes targeting timeliness of primary percutaneous coronary intervention. 2
ST-Elevation Myocardial Infarction: Which Patients Do Quality Assurance Programs Include?Summary: In the United States, efforts are underway to improve timely access to percutaneous coronary intervention in ST-elevation myocardial infarction (STEMI). The Joint Commission (TJC) and the American College of Cardiology National Cardiovascular Data Registry (NCDR) have developed standardized definitions and clinical performance measures for STEMI. The purpose of this study was to determine differences in 3 quality assurance registries for STEMI patients. STEMI patients presenting to the Minneapolis Correspondence to The Edito...
