IL6 and diabetes mellitus: Although diabetes is clearly associated with impaired EDC-mediated repair of myocardium [9] and greater LTS score, poorer glycemic control (i.e., greater HbA1c) alone did not linearly correlate with changes in IL-6 (p = 0.69), SDF1α (p = 0.43) and exosome production (p = 0.82).
