Evaluation Of Cardiac Function In Children 0n Regular Heamodialysis

April 26, 2022 updated by: Fatma Ahmed Sahy, Sohag University

Cardiovascular disease (CVD) is considered as the predominant cause of mortality and morbidity in chronic kidney disease (CKD) patients .

  • Left ventricular diastolic and systolic dysfunction and left ventricular hy pertrophy (LVH) contribute to the increased cardiovascular mortality rate in these patients .Such changes have been observed in young adults and children on prolonged dialysis
  • The cardiovascular mortality and morbidity are seen in earlier stages of CKD, and the risk is increased by multiple risk factors such as sodium and fluid retention,hypertension, anemia, inflammation and hyperparathyroidism .
  • Left ventricular hypertrophy is a common finding in CKD patients [8] and its severity increases with increasing severity of CKD . Initially, LVH is discussed as a physiological response to volume and pressure overload. However, sustained overload in combination with CKD associated risk factors may result in maladaptive LVH characterized by structural changes in the myocardium (calcification, fibrosis and collagen accumulation), resulting in diastolic and systolic dysfunction .
  • Causes of LV diastolic dysfunction are impaired active LV relaxation or decreased LV compliance.These changes are reflected in low diastolic volume for a given diastolic pressure, meaning reduced passive LV filling .
  • Changes in cardiac structure and function are common among the patients with chronic kidney disease undergoing hemodialysis. As early as 1827, Richard Bright drew attention to the common presence of left ventricular hypertrophy and thickening of the aortic wall in the patients with end-stage renal disease (ESRD).

  • Cardiovascular (CV) disease is the leading cause of mortality in the childhood renal replacement therapy population with long-term observational studies reporting 40-45% deaths attributable to CV disease , increasing to 57% when stratified to haemodialysis patients only . In children with CKD, left ventricular hypertrophy (LVH) is common and occurs early in the disease process with reported prevalence up to 65% and increasing to 82% in those on haemodialysis .

    • The present study stresses the importance of echocardiography as the gold standard for the diagnosis of cardiac disease in pediatric patients under maintenance HD as a high-risk population for cardiac diseases.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

2 years to 18 years (ADULT, CHILD)

Sampling Method

Non-Probability Sample

Study Population

All patients (2-18) years were undergoing regular HD, who were started on dialysis when GFR was ≤15 mL/min/1.73 m 3 three times per week, with each dialysis session lasting for 3-4 h.

Description

Inclusion Criteria:

  • All patients (2-18) years were undergoing regular HD, who were started on dialysis when GFR was ≤15 mL/min/1.73 m 3 three times per week, with each dialysis session lasting for 3-4 h.

Exclusion Criteria:

  • Patients of primary cardiac diseases (e.g., congenital or rheumatic heart disease, cardio- myopathy).

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Left ventricular mass (LVM).
Time Frame: one year
Left ventricular mass (LVM) will be calculated using the measurements obtained by two-dimensional directed M-mode echocardiography according to the American Society of Echocardiography (ASE) criteria . Indexed LVM (LVMI) will be calculated by dividing the LVM by height raised to a power of 2.7 (g/m2.7) using the formula devised by De Simone et al(De Simone G1992)
one year
Diastolic function .
Time Frame: one year
Diastolic function will be assessed by both Doppler echocardiography and tissue Doppler imaging. Early mitral inflow velocity (E), and late mitral inflow velocity (A) will be measured by Doppler echocardiography. Early (e) and late (a') peak mitral annular velocities will be measured at the medial and lateral mitral annulus using tissue Doppler. The e'/a' ratio at both annuli will be calculated. The peak early mitral annular velocity (E') will be computed as the average of the velocities at the medial and lateral annuli. Using these measurements, the ratio of Doppler-derived peak early mitral inflow velocity to tissue Doppler-derived peak early mitral annular velocity (E/E'ratio) will be calculated.
one year
The left ventricular myocardial performance index (MPI).
Time Frame: one year
The left ventricular myocardial performance index (MPI), a global index of systolic and diastolic function, will be defined as the sum of isovolumic relaxation time and isovolumic contraction time divided by ejection time.
