Poor sleep quality related to worse vascular function in individuals with multiple sclerosis

Background: Poor sleep quality has been related to poor vascular function and higher risk of cardiovascular disease in the general population. Persons with multiple sclerosis (MS) exhibit a high cardiovascular risk, and report poor sleep quality. To date, the association between sleep quality and vascular health in MS has not been investigated. Objective: To investigate differences in vascular health between good and poor quality sleepers with MS. Methods: After a 10 minute rest in the supine position, resting heart rate (HR) and brachial blood pressure (BP) were collected.Aortic SBP, augmentation index (AIX), HR normalized AIX (AIX@HR75), subendocardial viability ratio (SEVR), end systolic pressure (ESP), and central pulse wave velocity (PWVc) were measured with applanation tonometry in individuals with MS (n=49).
