Subclinical Myocardial Dysfunction in Children With Wilson's Disease

12 augusti 2026 uppdaterad av: Hebatullah Fawzy

Assessment of Subtle Myocardial Dysfunction in Children With Wilson's Disease: A Case-Control Study

Wilson's disease (WD) is one of the most common metabolic liver diseases in older children. The most frequent clinical presentation is liver disease. However, Wilson's disease (WD) is a multisystem disorder. It is concluded that four modes of cardiac manifestations in Wilson's disease (WD) include arrhythmias, cardiomyopathy, cardiac death, and autonomic dysfunction. Such possible cardiac involvement should be added to the clinical picture of Wilson's disease (WD) involving the hepatic and central nervous system(CNS).

The data on cardiac manifestations in children is very limited and only few adult studies are available.

In this study, the investigators aim to unveil subclinical cardiac dysfunction in children with Wilson's disease with apparently normal cardiac functions by conventional assessment.

Studieöversikt

Detaljerad beskrivning

Wilson's disease (WD) is an autosomal recessive metabolic liver disorder caused by toxic copper accumulation. While hepatic and neurological manifestations are well recognized, copper can also accumulate in cardiac tissue, potentially leading to subtle myocardial changes, arrhythmias, and heart failure. Traditional two-dimensional (2D) echocardiography often appears normal in early stages. This study aims to evaluate early left ventricular (LV) systolic and diastolic dysfunction in pediatric patients with Wilson's disease using speckle tracking echocardiography (STE) and tissue Doppler imaging, and to correlate these findings with serum levels of Pro-Brain Natriuretic Peptide (Pro-BNP) and ceruloplasmin.
