TNNI3 and type 2 diabetes mellitus: Correlation analyses undertaken on all T2DM patients with ACS showed that NHR level was positively correlated with cTnI (r = 0.437, p < 0.001), CK (r = 0.258, p < 0.001), CK-Mb (r = 0.447, p < 0.001), LDH (r = 384, p < 0.001), Mb (r = 0.320, p < 0.001), LA (r = 0.168, p = 0.042) and LV levels (r = 0.283, p = 0.001) and negatively correlated with EF (r = − 0.327, p < 0.001) and FS levels (r = − 0.347, p < 0.001, Table 2, Fig. 3(*p < 0.05, **p < 0.01 and ***p < 0.001)).
