In their study cohort, the authors demonstrated that serum EV long non-coding RNA (lncRNA) NEAT1 and matrix metalloproteinase 9 (MMP-9) levels were significantly higher in serum EV from STEMI patients compared to those from healthy controls, whereas EV-bound miR-204 levels negatively correlated with STEMI diagnosis. This evidence concerns the gene MMP9 and ST Elevation Myocardial Infarction.
