Cardiac Involvement in Hereditary Ataxias

Although much attention has been focused on the neurological sequelae of the hereditary ataxias, patients with these conditions also may develop cardiac complications that represent a significant cause of disability and even death. In this article, the authors describe the hereditary ataxias with known cardiac involvement, discuss underlying causes, and review guidelines for screening and treatment. Continued progress will require coordinated clinical trial networks, interdisciplinary care teams, and team science.
