Assessing Cardiac Functions in Hemodialysis Patients Using by Tissue Doppler Imaging

Abstract

Aim: Heart failure is an important cause of morbidity and mortality in end-stage renal disease patients. It is important to diagnose and take precautions before heart failure develops in this group of patients. We aimed to evaluate diastolic dysfunction, which may be the first stage of heart failure using tissue Doppler imaging (TDI) in hemodialysis (HD) patients.Methods:The study included 49 patients receiving HD treatment and 46 healthy controls matched for age and sex. Echocardiographic evaluation includingtissue Doppler measurements was performed to all participants.Results: Early diastolic peak (Em) was lower, late diastolic peak (Am) was significantly higher in the HD group (p <0.001 and p = 0.042, respectively). Em / Am ratio was statistically lower inthe HD group (p <0.003). There was no statistically significant difference in IVCT, ET and MPI between the groups. IVRT was statistically higher in the HD group (p <0.001).Conclusion: In our study, the frequency of diastolic dysfunction was found to be higher in HD patients compared to the control group by tissue Doppler imaging. We think that the use of TDI to detect diastolic dysfunction at an early stage may be important in this group of patients and may be used for screening
