A Winning Hand in Cardiology: Queen of Hearts AI Model Enhances OMI Detection

Background: Cath lab activation based on ST-elevation myocardial infarction (STEMI) criteria is founded on aging data and requires evolution. In the “Occlusive Myocardial Infarction (OMI) Manifesto,” emergency physicians Dr. Steve Smith, Dr. Pendell Meyers, and Dr. Scott Weingart introduced a ...

REBEL Cast Ep114: High Flow O2, Suspected ACS, and Mortality?

Background: Historically, we have treated acute coronary syndrome with supplemental oxygen regardless of the patient’s oxygen saturation.  This intervention was based on the belief that pushing the patient’s PaO2 to supra therapeutic levels would increase O2 delivery to ischemic myocardium ...

CCTA vs Invasive Coronary Angiography in NSTEMI

Background: Coronary pathology in patients with NSTEMI can range from structurally normal vessels to varying degrees of nonobstructive coronary artery disease (CAD) to extensive obstructive CAD affecting the coronary tree.  The current diagnostic pathway to differentiate these different coronary pathologies ...

Upping Our ECG Game: OMI vs STEMI

Background: Occlusion myocardial infarction (OMI) is defined as acute coronary occlusion or near occlusion with insufficient collateral circulation leading to downstream myocardial infarction. Currently, we use STEMI ECG criteria to identify acute coronary OMI in the clinical setting. The diagnosis ...
