Compared with participants whose BP declined during sleep (so-called dippers), those whose BP rose (“risers”) had higher risks at a mean follow-up of 4.5 years for heart failure and atherosclerotic cardiovascular disease events, independent of office or 24-hour measurements of systolic BP. Also, each 20 mm Hg elevation in nighttime systolic BP was associated with a 36% increase in risk for heart failure and a 21% increase in risk for cardiovascular events in analyses adjusting for demographic and clinical variables.
