Insights
Screening for Fabry disease (FD) in cardiac patients under 70 with pacemaker-requiring conduction problems found no cases. Current screening for FD in cardiac patients should not include this specific population.
Area of Science:
- Cardiology
- Genetics
- Rare Diseases
Background:
- Fabry disease (FD) diagnosis in cardiac patients has primarily focused on left ventricular hypertrophy.
- Conduction abnormalities in FD may indicate earlier disease stages and potential for earlier diagnosis.
Abstract:
Identification of Fabry disease (FD) in cardiac patients has been restricted so far to patients with left ventricular hypertrophy. Conduction problems are frequent in FD and could precede other manifestations, offering a possible earlier diagnosis.We studied the prevalence of FD in 188 patients < 70 years with conduction problems requiring pacemaker implantation. Although classical manifestations of FD were not rare, no patient with FD was identified. Screening efforts should not be conducted in this population.
