Friedreich's ataxia (FA) represents a degenerative, genetically determ
ined disease of the nervous system in combination with myocardial affe
ction and in some cases endocrinological disturbances. Manifestation o
f myocardial involvement usually follows symptoms of nervous system de
generation later in the course, but seems not to be secondary. These c
ardiac disturbances are the main cause of death in FA-patients. Therap
eutic management of heart disease is possible and interdisciplinary ne
urologic-cardiologic cooperation should start early in the course of F
A.
