Impact of sleep disorders on hypertension: a multifaceted approach

Abstract

Sleep Disorders are increasingly common clinical conditions in our Society. Among these, we highlighted two of them: Obstructive Sleep Apnea (OSA) and short sleep duration (SSD). Previous studies suggested a positive association of sleep disorders with several cardiovascular diseases, including hypertension (HTN). Despite the advances in the area, several important issues remain poorly explored: 1) in isolation, both OSA and SSD are associated with HTN. However, studies that evaluated OSA did not consider the presence of CDS and vice versa. In addition, most of the studies evaluated sleep duration subjectively; 2) the role of OSA in target organ damage (TOD) in HTN is unclear; 3) the prognostic impact of OSA on resistant hypertension has not been studied; 4) the interaction of OSA with other causes of secondary HTN was little explored; 5) according to a recent statement from the American Heart Association, the effects of CPAP on blood pressure (BP) is still not well established, including in hypertensive patients with comorbidities, such as patients with chronic kidney disease; 6) the effect of CPAP on BP reduction is variable and the development of biomarkers predicting BP response and increased cardiovascular risk is highly desirable. Using a multidisciplinary and international collaboration approach, this Thematic Project aims to answer questions with clear clinical relevance on the impact of sleep disorders on HTN and TOD, the effect of OSA treatment on BP and TOD, the evaluation of potential mechanisms involved and the potential creation of biomarkers that predict risk and response to OSA treatment.
