Myocardial Changes in Pediatric Guillain-Barré Syndrome

September 21, 2026 updated by: Maria Magdy Monir, Assiut University

Myocardial Changes in Pediatric Patients With Guillain-Barré Syndrome

This prospective cohort study aims to identify and characterize cardiac changes including electrocardiographic, echocardiographic, and biochemical abnormalities in pediatric patients with Guillain-Barré syndrome.

Study Overview

Status

Not yet recruiting

Conditions

Detailed Description

Guillain-Barré syndrome can be associated with cardiac autonomic dysfunction and myocardial involvement. This observational study will include pediatric patients (1 month to 18 years) with confirmed Guillain-Barré syndrome.

Participants will undergo electrocardiography, echocardiography, and cardiac biomarker assessment at hospital admission and at 3-month follow-up.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Prevalence of cardiac abnormalities
Time Frame: Baseline

Baseline

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
