dc.description.abstractIntroduction Oxidative stress is known to affect left ventricular functions negatively. There is a strong bidirectional connection between diabetes mellitus (DM) and oxidative stress. In parallel, left ventricular dysfunction is observed more frequently, even in patients with DM without other risk factors. In this context, the objective of this study is to comparatively investigate the potential relationship between oxidative stress and subclinical left ventricular dysfunction (SCLVD) assessed by Myocardial Performance Index (MPI) in patients with and without DM. Research design and methods The sample of this observational cross-sectional single-center study consisted of 151 patients who were evaluated for oxidative stress and SCLVD by tissue Doppler echocardiography. Patients' total oxidant status (TOS), total antioxidant status (TAS), and Oxidative Stress Index (OSI) values were calculated. The effects of oxidative stress and DM on MPI were analyzed. Results There were 81 patients with DM (mean age: 46.17 +/- 10.33 years) and 70 healthy individuals (mean age: 45.72 +/- 9.04 years). Mean TOS and OSI values of the DM group were higher than healthy individuals (5.72 +/- 0.55 vs 5.31 +/- 0.50, p = <0.001; and 4.92 +/- 1.93 vs 1.79 +/- 0.39, p = <0.001; respectively). The mean TAS value of the DM group was significantly lower than the healthy group (1.21 +/- 0.40 vs 3.23 +/- 0.51, p = <0.001). There was a significant correlation between OSI and MPI mitral in the DM group (R 0.554, p = <0.001) but not in the healthy group (R -0.069, p=0.249). Conclusions Both oxidative stress and myocardial dysfunction were found to be more common in patients with DM. The study's findings indicated the negative effect of oxidative stress on myocardial functions. Accordingly, increased oxidative stress caused more significant deterioration in MPI in patients with DM compared with healthy individuals.
