title: Cardiovascular complications of respiratory diseases.
abstract: A major burden of morbidity and mortality due to respiratory diseases can be directly related to the cardiovascular (CV) complications of these disorders. Evidence from cross-sectional and longitudinal studies link reduced lung function and cardiovascular diseases. However, the underlying pathogenic mechanisms are unclear. Hypoxia-induced increased sympathetic activity, blood viscosity, or inflammation, among other factors, may mediate the underlying pathogenesis. In addition, sleep-disordered breathing (SDB) has been implicated by association in multiple CV diseases including hypertension, ischemic heart disease, congestive heart failure, arrhythmias, and stroke. However, the exact contribution of SDB, including obstructive and central sleep apneas, to the development of cardiovascular diseases is not fully understood. In this context, the contribution of the new large, prospective, Jackson Heart Study could be significant in that it is designed to answer several of these questions, specifically in the African American population. This review examines the current evidence that links both reduced lung function and SDB to CV diseases.
