CRP and ST Elevation Myocardial Infarction: When analyzing the associations of inflammatory stress parameters, we observed strong significant positive correlations between CRP levels with plasma levels of miR-223-3p (R = 0.587, p < 0.001), miR-486-5p (R = 0.557, p < 0.001), miR-146a-5p (R = 0.521, p < 0.001), miR-125a-5p (R = 0.465, p = 0.001), miR-155-5p (R = 0.404, p = 0.006), miR-142-3p (R = 0.327, p = 0.026), cfDNA (R = 0.382, p = 0.011), and mtDNA (R = 0.362, p = 0.017) in STEMI patients at T1.
