Abstract:Objective To observe the levels change of serum peroxisome proliferator-activated receptors (PPARs) in patients with diabetic cardiomyopathy and to discuss its possible mechanism. Methods The levels of serum PPARs were examined by ELISA methods in 74 DCM patients (DCM group), 71 T2DM patients without DCM (DCM group) and 70 normal control group (NC group) in our hospital from October 2016 to October 2017. Results The FPG, HbA1c, TG and hs-CRP were higher in DCM group than those in T2DM group and in NC group (P?0.05); the FPG, HbA1c and TG were higher in T2DM group than those in NC group (P?0.05); the PPARα and PPARγ were higher, and PPARβ/δ were lower in DCM group than those in T2DM group and in NC group (P?0.05); the PPARα and the PPARγ were higher, and the PPARβ/δ were lower in T2DM group than those in NC group (P?< 0.05). Conclusions The levels of PPARα and PPARγ are increased, and the levels of PPARβ/δ are decreased in patient with DCM. Therefore, PPARs may play an important role in the development of DCM.
