Tissue Doppler Imaging versus Conventional Echocardiography in Evaluation of Cardiac Functions in Diabetes Mellitus

Background: Conventional echocardiography and tissue Doppler imaging have been highlighted to diagnose diastolic and systolic heart dysfunction. We aimed to compare tissue Doppler imaging with conventional echocardiography to diagnose heart dysfunctions in diabetes mellitus type 1 (DMT1) patients. Materials and Methods: This case-control study was conducted in the Ali Asghar Clinic, Zahedan, Iran. The study lasted from 2017 to 2018 on 140 participants aged from 4-18 years, and consisted of 70 patients with DMT1, and 70 children who referred to hospital for checkup as control group. The participants went under tissue Doppler imaging and conventional echocardiography (M mode and 2D) by an invariable cardiologist. The 5 ml blood samples were taken to test blood leptin and ferritin. The data were analyzed using SPSS software (version 18.0). Results: Conventional findings such as left and right deceleration time, left, and right peak E velocity, left ejection time, left Myocardial performance index and TDI findings such as left, and right ET’, right S’, right E’, left MPI’, right MPI’, and left E/E’ were different in patients and the control group (p<0.05). Left and right deceleration time, and LV Mass index in conventional and left ET’, right ET’ in TDI were different in age groups of patients (p<0.05). In sex groups, left deceleration time, left peak A velocity, right acceleration time, right deceleration time and right E/A in conventional and left ET’, left ICT’, left IRT’, right ICT’, right IRT’, right S’ and right MPI’ in TDI were different (p<0.05). Conclusion: This study concluded that both conventional and TDI were different between DMT1 patients and the control group, but TDI was stronger in discrimination.
