Background Several studies have demonstrated that complete revascularisation improves clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary disease. However, the optimal timing of non-culprit lesion revascularisation remains controversial.

Aim Acute injury and subsequent remodelling responses to ST-segment elevation myocardial infarction (STEMI) are major determinants of clinical outcome. Current imaging and plasma biomarkers provide delayed readouts of myocardial injury and recovery. A cell culture model was used to identify endothelial cell–derived miRs.

In the unmatched STEMI subgroup, all-cause mortality was significantly higher in females driven by older age (P < 0.001). vs. 5.2%; P = 0.749).

When total LM occlusion does present with STE in aVR, there is ALWAYS ST Elevation elsewhere which makes STEMI obvious; in other words, STE is never limited to only aVR but instead it is part of a massive and usually obvious STEMI. All are, however, clearly massive STEMI. This is her ECG: An obvious STEMI, but which artery?

This is a troponin I level that is almost exclusively seen in STEMI. In this case, profound shock for 1 hour would result in the same degree of infarction. A followup ECG was recorded 2 days later: No definite evidence of infarction. So this is either a case of MINOCA, or a case of Type II STEMI. Troponin I rose to 44.1
