Detailed Description

Chronic kidney disease (CKD) is a complex and multifaceted disease that causes renal dysfunction and progression to end-stage kidney disease.

Cardiovascular risk is common in patients with end-stage renal disease on hemodialysis, many studies have shown that the risk of adverse cardiovascular events is significantly increased and persistent in all patients treated with hemodialysis, especially those who have just started hemodialysis treatment.

Patients with end-stage renal disease have elevated levels of cardiac biomarkers, despite no apparent signs of cardiac dysfunction or radial damage; this is related to chronic kidney disease comorbidities and reduced renal clearance per se.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Study group
Children with end-stage chronic kidney disease (CKD) on regular maintenance hemodialysis.
Device: Two-Dimensional Speckle-Tracking Echocardiography (2D-STE)
2D speckle-tracking echocardiography was used to assess left ventricular myocardial deformation. Standard apical four-, two-, and three-chamber views were acquired with optimized frame rates.
Device: Three-Dimensional Speckle-Tracking Echocardiography (3D-STE)
Three-dimensional datasets were acquired from apical full-volume images, ensuring optimal electrocardiographic gating, adequate frame rates, and high-quality image acquisition.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Left ventricular systolic function
Time Frame: At baseline
Left ventricular systolic function was evaluated by calculating the left ventricular ejection fraction (LVEF) using the biplane Simpson's method from apical four- and two-chamber views.
