Beyond the ST-segment in Occlusion Myocardial Infarction (OMI): Diagnosing the OMI-nous

Area of Science:

• Cardiology
• Medical Diagnostics
• Pathophysiology

Background:

• The ST-segment elevation (STE) myocardial infarction (MI)/non-STEMI (NSTEMI) classification has been standard in emergency cardiology for three decades.
• While revolutionary, this paradigm now impedes advancements in modern MI care.
• The classification is based on electrocardiographic signs rather than the underlying pathology of acute coronary occlusion (ACO).

Purpose of the Study:

• To analyze the historical development of the STEMI/NSTEMI classification.
• To identify the clinical consequences arising from labeling MI based on surrogate electrocardiographic markers.
• To advocate for the adoption of a new paradigm, occlusion MI (OMI)/non-occlusion MI (NOMI), based on ACO.

Main Methods:

• Historical analysis of MI classification systems.
• Review of clinical implications of the STEMI/NSTEMI paradigm.
• Conceptual proposal for the OMI/NOMI paradigm.

Main Results:

• The established STEMI/NSTEMI classification is a surrogate marker for the actual pathology of acute coronary occlusion (ACO).
• This mislabeling has led to significant clinical consequences in MI management.
• The OMI/NOMI classification offers a more accurate and clinically relevant approach.

Conclusions:

• The current STEMI/NSTEMI paradigm is an obstacle to modern MI care progression.
• Revising the classification to OMI/NOMI, focusing on acute coronary occlusion, is crucial.
• Adopting the OMI/NOMI paradigm will facilitate more effective and precise management of myocardial infarction.
