Monitoring heart rhythms in patients with Fabry disease

Natural History of Cardiac Rhythm and Conduction Disorders in Patients With Fabry Disease Evaluated by Long-Term Implantable Holter ECG

Not applicable Interventional Institut National de la Santé Et de la Recherche Médicale, France · NCT04440254

This study is testing how heart rhythms change over three years in people with Fabry disease using a special heart monitor to see how it relates to their overall heart health.

What this trial studies

This study aims to monitor cardiac arrhythmias and conduction disorders in patients with Fabry disease over a three-year period using an implantable Holter ECG device. It will involve 40 patients, half of whom have left ventricular hypertrophy, and will assess the relationship between these cardiac anomalies and changes in cardiac MRI, echocardiographic parameters, and overall disease severity. The study is non-blinded and non-randomized, focusing on the long-term effects of Fabry disease on heart health.

Who should consider this trial

Good fit: Ideal candidates are male patients aged 18 and older with a confirmed morbid mutation for Fabry disease and no significant heart conditions.

Not a fit: Patients with a history of myocardial infarction, significant valve disease, or those currently on corticosteroids or immunosuppressive drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring and management of cardiac complications in patients with Fabry disease.

How similar studies have performed: While there have been studies on cardiac monitoring in other conditions, this specific approach in Fabry disease is relatively novel and untested.
