Screening for Fabry Disease in Portuguese Patients with Heart Conditions

Frequency of Fabry Disease in Portuguese Patients With Idiopathic Cardiomyopathies

Observational Universidade do Porto · NCT05409846

This study is testing how common Fabry disease is in Portuguese patients over 30 with unexplained heart problems to see if it affects their condition.

What this trial studies

This observational study aims to assess the prevalence of Fabry disease among Portuguese patients diagnosed with various idiopathic cardiomyopathies. It will involve screening patients over the age of 30 who exhibit unexplained heart conditions, including hypertrophic and dilated cardiomyopathy. The methodology includes testing for alfa-galactosidase activity and conducting genetic tests to confirm Fabry disease diagnosis. The study seeks to fill the knowledge gap regarding the impact of Fabry disease on different cardiac phenotypes.

Who should consider this trial

Good fit: Ideal candidates are patients over 30 years old with unexplained hypertrophic or dilated cardiomyopathy.

Not a fit: Patients who have previously been diagnosed with Fabry disease or have identified genetic variants causing their cardiomyopathy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnosis and management of Fabry disease in patients with unexplained heart conditions.

How similar studies have performed: While the prevalence of Fabry disease in this specific population is largely unknown, similar screening approaches have been successful in other regions, indicating potential for meaningful findings.
