A 22-Year Follow-up Study of Long-term Cardiac Outcome and Predictors of Survival in Friedreich Ataxia

Abstract

Survival in FRDA is determined by cardiac complications, which are dependent on the mutation (ie, the size of the expanded GAA repeat). Patients with progressive decline of the left ventricular ejection fraction had a worse prognosis. This finding demonstrates that cardiac follow-up is important in FRDA to identify individuals at risk for further cardiac complications.
