Long-term treatment of ischemic dilated cardiomyopathy with continuous positive airway pressure
Abstract:
An 81-year-old man with ischemic dilated cardiomyopathy complained of frequently awakening from sleep due to choking; subsequent polysomnography revealed Cheyne-Stokes respiration (CSR) with sleep apnea. With continuous positive airway pressure (CPAP) through a nasal mask, both the CSR and symptoms disappeared. After 6-12 months, chest X-ray and echocardiographic findings continued to improve without any change in pharmacological treatment. For three years, CPAP had been effective to eliminate CSR during sleep. Long-term CPAP treatment, which is rarely applied for congestive heart failure in Japan, is useful in alleviating the adverse effects of CSR and, thereby, maintaining a good quality of life in these patients.
