Obscure cardiomyopathies with coronary artery changes

Coronary disease, cardioneuropathy, and conduction system abnormalities in the cardiomyopathy of Friedreich's ataxia.

“…Previous studies have unequivocally shown that the small coronary arteries are abnormal in patients who have cardiac disease and Friedreich's ataxiaS 6 [8][9][10][11][12]; but the functional significance of this finding has been challenged, particularly by Hewer"1 whose findings have been widely quoted in virtually all subsequent reviews. In the present report we describe our own findings in three patients, which support the importance of small coronary artery disease, and show why we believe that Hewer's personal observations do in fact accord our findings.…”
