The evolution of 15 patients initially evaluated during Phase One of the Quebec Cooperative Study of Friedreich's ataxia has been studied approximately three years later. It is concluded that the deterioration of cardio-pulmonary function in Friedreich's ataxia is multifactorial. The neuromyopathy (or the underlying metabolic or cellular defect) appears to be the main contributing factor to the deterioration of cardio-pulmonary function, which is exacerbated by the scoliosis and varying severity of the cardiomyopathy.
