A-35 | Is it Time for a Paradigm Shift Towards Occlusion Myocardial Infarction?

A subset of NSTEMI patients have culprit artery occlusion aka myocardial infarction (OMI). We aimed to identify this with OMI, and the impact revascularization timing on their cardiovascular (CV) outcomes. This is a retrospective study. Patients presenting who underwent cardiac catheterization between January 2017 December 2020 were identified, followed for later 5 years or time conclusion OMI was defined as stenosis > 90% TIMI flow < 3. Cardiac 24 hours (from first elevated troponin) termed delayed. Primary endpoint all cause mortality, CV death, recurrent MI, stroke heart failure at 30 days. Secondary end points death all-cause mortality 1 years. total 488 105 (21%) satisfied criteria OMI. Baseline characteristics comparable among Non-OMI (NOMI) group. Among delayed catheterisation (N=270), day higher in group when compared NOMI (P=0.04). Of patients, days, those versus an early intervention (P<0.05). Our study identified 21% these 48% had 100% artery. worse outcomes received intervention. effect more pronounced All-cause intervention, thus representing high risk Future studies should be would benefit from revascularization.
