Insights

Non-alcoholic fatty liver disease in obese children is linked to early heart dysfunction. Three-dimensional speckle tracking echocardiography can detect this subclinical left ventricular dysfunction, even with normal ejection fraction.

Area of Science:

  • Pediatric Cardiology
  • Hepatology
  • Cardiovascular Imaging

Background:

  • Non-alcoholic fatty liver disease (NAFLD) is increasingly prevalent in obese children.
  • NAFLD is associated with metabolic syndrome and cardiovascular risk factors.
  • Early detection of cardiac involvement in pediatric NAFLD is crucial.

Purpose of the Study:

  • To evaluate left ventricular (LV) function in children with NAFLD using 3D speckle tracking echocardiography (3DSTE).
  • To identify subclinical LV dysfunction in pediatric NAFLD patients.
  • To correlate LV strain parameters with NAFLD severity.

Main Methods:

  • A case-control study involving 40 obese children with NAFLD, 40 obese children without NAFLD, and 40 healthy controls.
  • Comprehensive echocardiography including 3DSTE to assess LV global longitudinal, circumferential, radial, and area strain.
  • Laboratory tests including lipid profile and Troponin I levels were performed.

Main Results:

  • Children with NAFLD exhibited abnormal lipid profiles and elevated Troponin I levels.
  • 3DSTE revealed significantly reduced LV global longitudinal, circumferential, radial, and area strain in children with NAFLD.
  • These strain parameters were negatively correlated with NAFLD grade, despite normal LV ejection fraction by conventional echocardiography.

Conclusions:

  • Pediatric NAFLD is associated with subclinical LV dysfunction.
  • 3DSTE is a valuable tool for detecting early LV dysfunction in children with NAFLD.
  • Early identification of cardiac involvement can guide timely interventions in pediatric NAFLD.
