The heart of sleep: sleep-disordered breathing and heart failure.
Heart failure is associated with high rates of hospitalization and mortality as well as great economic burden in the United States. Recent data show that a high percentage of patients with depressed left ventricular ejection fractions suffer from sleep-disordered breathing, contributing to this incidence of morbidity and mortality. Since the signs and symptoms associated with sleep disorders do not differ significantly from chronic heart failure signs and symptoms, detection and recognition of sleep-disordered breathing is a clinical challenge. Thus clinicians frequently fail to recognize it as a possible contributor to the development of heart failure or as a consequence of the disease. This article discusses sleep, sleep-disordered breathing, its effects and consequences on the cardiovascular system, strategies for identifying at-risk individuals, and treatment options.
