The OMI/NOMI paradigm identified patients with shorter median door-to-angiography time (39 vs 540 minutes) and similar in-hospital mortality (4.1%) compared to traditional STEMI/NSTEMI classification in ACS patients.

Does the OMI-NOMI diagnostic paradigm improve prognostic precision and identify urgent reperfusion needs better than the traditional STEMI-NSTEMI framework in patients with acute coronary syndrome?
A significant proportion of ACS patients without ST-elevation have acute coronary occlusion (STEMI- OMI) and suffer delayed reperfusion, highlighting the limitations of relying solely on the traditional STEMI/NSTEMI paradigm for urgent angiography triage.
Effect estimate: null
Absolute Event Rate: 4.1% vs 4.1%
p-value: p=0.963
In this cohort, 46.1% of patients were classified as STEMI - OMI, experiencing markedly longer reperfusion delays than STEMI + OMI patients (median door-to- angiography time: 540 vs. 39 min). These findings suggest that the OMI-NOMI paradigm may offer greater prognostic precision and therapeutic guidance than the traditional STEMI-NSTEMI framework, particularly for patients presenting with chest pain who require emergent angiography/PCI. An occlusion-centered diagnostic approach may expedite reperfusion and improve clinical outcomes in ACS.
Ümit et al. (Tue,) conducted a observational in acute coronary syndrome (n=482). Occlusion myocardial infarction (OMI) vs Non-occlusion myocardial infarction (NOMI) diagnosis paradigm vs. Traditional STEMI/NSTEMI paradigm was evaluated on In-hospital mortality after angiography/percutaneous coronary intervention (null, p=0.963). The OMI/NOMI paradigm identified patients with shorter median door-to-angiography time (39 vs 540 minutes) and similar in-hospital mortality (4.1%) compared to traditional STEMI/NSTEMI classification in ACS patients.
