In clinical situations, the diagnosis of OMI requires a super electrocardiogram (ECG) expert or use of artificial intelligence like the Queen of hearts. For research purposes, we try to use high\u2010sensitivity cardiac troponin T (hs\u2010cTnT) to help retrospectively classify ECGs as indicating OMI or not among patients treated as NSTEMI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aims<\/jats:title>\n                    <jats:p>To evaluate the association between hs\u2010cTnT and angiographic occlusion in patients treated as NSTEMI.

Among these patients, we initially selected all patients with TIMI flow 0\u20132, constituting the \u00ab OMI \u00bb group; subsequently, we included consecutively those patients admitted within the first 3 months with TIMI flow 3, constituting the \u00ab NOMI \u00bb comparison group. ROC curve analysis was performed to identify hs\u2010cTnT thresholds, and predefined cutoffs (1000\u2009ng\/L and 10,000\u2009ng\/L) were evaluated. The value of hs\u2010cTnT used was the highest prior to coronary angiography. The setting of hs\u2010cTnT to define coronary occlusion was inspired by previous works in the literature done for research purposes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      200 patients were included (31 OMI, 169 NOMI) among patients treated as NSTEMI in 2024. In multivariable analysis, persistent chest pain (OR 2.6; 95% CI: 1.06\u20136.40;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.037) and de novo wall motion abnormality (OR 3.41; 95% CI: 1.30\u20138.89;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.012) were independently associated with coronary occlusion. ROC analysis identified 678\u2009ng\/L as the optimal threshold of hs\u2010cTnT (AUC\u2009=\u20090.58) with 71% sensitivity (Se) and 65% specificity (Sp). The negative predictive value (NVP) and positive predictive value (PPV) were respectively 91% and 22% in the patient population studied.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Coronary occlusion was found in 15% of patients treated as NSTEMI in our cohort. Subject to limitations such as the non\u2010use of peak troponin levels and the exclusion of TIMI\u20103 flow from the OMI group, which led to an underestimation of prevalence, the hs\u2010cTnT threshold of 678\u2009ng\/L was associated with coronary occlusion in patients treated as NSTEMI, with modest sensitivity (Se), good NPV, modest Sp, and poor PPV. As troponin testing is non\u2010specific, the troponin threshold should not be used independently to classify patients treated as NSTEMI into OMI or NOMI. An early ECG interpreted using artificial intelligence is currently the most reliable method for diagnosing OMI.<\/jats:p>\n
