Beyond ST-elevation myocardial infarction (STEMI): High-risk ECG patterns as predictors of occlusive myocardial infarction in out-of-hospital cardiac arrest patients
Authors' conclusion
Combining STEMI and high-risk ECG criteria improves OMI prediction compared to STEMI criteria alone, potentially enabling faster treatment and better OHCA survival.
Study context
- Population
- Out-of-hospital cardiac arrest (OHCA) patients undergoing coronary angiography
- Participants
- 97 patients
- Exposure
- STEMI vs High-risk ECG vs Neither
- STEMIn = 31reference
- High-risk ECGn = 29
- Neithern = 37
- Outcome
- Occlusive MI (OMI) on coronary angiography
Main finding
As reported in the abstract
OMI
%
- Occlusive myocardial infarctions (OMI) overall
- 55 (53/97)
- STEMI plus high-risk ECG criteria would have predicted OMI
- 92 (49/53)
Observational data: associations, not effects.
