BackgroundCardiac dysfunction is the major cause of morbidity and mortality in diabetes. Myocardial Performance Index (MPI/Tei Index) includes both systolic and diastolic time intervals to assess the global cardiac dysfunction. Our aim was to assess the MPI in patients with type 2 diabetes.Material and methodsThis hospital-based analytic observational study was performed in the tertiary care center. The conventional Doppler parameters, tissue Doppler-derived E/E′ and MPI, were measured in all patients.Results100 patients with type 2 diabetes were included in the study. 65 patients showed diastolic dysfunction, 33 with Grade I diastolic dysfunction, 23 with Grade II diastolic dysfunction, and 14 patients with Grade III diastolic dysfunction. The conventional Doppler showed abnormality in 44% of patients (33 patients with Grade I and 14 patient with Grade III). 23 patients were in Grade II diastolic dysfunction (12 patients showed reversal E/A on valsalva maneuver and 11 patients showed abnormality in tissue Doppler-derived E/E′, E/E′ > 15). MPI with cut-off 0.36 was found to have 94% sensitivity, 100 specificity, and 94% PPV for the detection of cardiac dysfunction. MPI negatively correlated with systolic dysfunction (rho = 0.455, p < 0.001) and positively correlated with grade of diastolic dysfunction (rho = 0.832, p < 0.001) and NYHA grading of dyspnea (rho = 0.872, p < 0.001)ConclusionsMPI as a single parameter can be used for assessment in diabetic cardiac dysfunction.
