Resistant hypertension and sleep apnea: Pathophysiologic insights and strategic management

Abstract

Resistant hypertension is common among adults with hypertension affecting up to 30% of patients. The treatment of resistant hypertension is important because suboptimal blood pressure control is the leading preventable cause of death worldwide. A frequent comorbid condition in patients with resistant hypertension is obstructive sleep apnea. The pathophysiology of sleep apnea-associated hypertension is characterized by sustained adrenergic activation and volume retention often posing treatment challenges in patients with resistant hypertension. This review will address some of the epidemiologic data associating apnea with the pathogenesis of resistant hypertension. Diagnosis and management of apnea and its associated hypertension will also be considered. © 2010 Springer Science+Business Media, LLC.
