MGP and myocardial ischemia: In the total group of control subjects and IHD patients without T2D, MGP correlated positively with hsCRP (r = 0.50, p < 0.0001) and YKL-40 (r = 0.30; p = 0.03), whereas it correlated negatively to hsCRP in the total group of T2D patients without and with IHD (r = -0.28, p = 0.03).
