We report the association between periodic leg movements (PLM) during sleep and congestive heart failure (CHF) in a patient who had a successful heart transplant. Pretransplant, the patient had chronic insomnia and CHF. Overnight polysomnography revealed severe PLM disorder and sleep disruption. Three months following transplantation his insomnia had resolved associated with a dramatic reduction in PLM.
