Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
