Trial Parameters
Brief Summary
The purpose of this project is to characterize measures of cardiac performance and neuromuscular physiology in FA patients using novel techniques, including echocardiography and magnetic resonance imaging (MRI), metabolic exercise testing, and neurophysiological outcomes.
Eligibility Criteria
Inclusion Criteria: * Genetic diagnosis of Friedreich's ataxia by DNA sequencing, mutational analysis or protein assay OR be a healthy subject with no evidence of a neuromuscular disorder * Between the ages of 6 and 70 (inclusive) * Are able to tolerate metabolic exercise testing * Are stable on cardiac medication regimen for 3 months prior to screening Exclusion Criteria: * Presence of unstable heart disease * Receipt of cardiac transplant * Any concurrent medical condition which, in the opinion of the investigators, would make the subject unsuitable for the study
