About this episode
Contributor: Travis Barlock, MD Educational Pearls: The presence of a STEMI has traditionally been used to determine if a patient with acute chest pain requires urgent cath lab management STEMI indicates an occluded coronary artery, and urgent intervention is needed to restore perfusion to ischemic tissue Patients with occluded coronary arteries can present with EKG findings other than STEMI 2022 ACC Expert Consensus Decision Pathway on the Evaluation and Disposition of Acute Chest Pain in the Emergency Department was recently published in the Journal of the American College of Cardiology Recognizes STEMI equivalents that necessitate cath lab management ST depression in precordial leads Indicates a posterior infarct/possible RCA occlusion LBBB c ST elevation meeting modified Sgarbossa criteria Hyperacute and/or De Winter T wave First indication of coronary artery occlusion Most beneficial time to initiate cath lab because more tissue is salvageable These recommendations will likely alter clinical practice for ED management of acute chest pain References Kontos MC, de Lemos JA, Deitelzweig SB, et al. 2022 ACC Expert Consensus Decision Pathway on the Evaluation and Disposition of Acute Chest Pain in the Emergency Department: A Report of the American College of Cardiology Solution Set Oversight Committee.
