Blood pressure while sleeping is an important risk factor for cardiovascular disease (CVD) events, a new study confirms. “The findings indicate a novel definition of true hypertension might rely on elevated asleep systolic BP and diminished sleep-time relative systolic BP decline (non-dipper/riser pattern), as these two variables, but not daytime office BP or awake ambulatory BP mean, are joint significant prognostic markers of increased risk for cardiovascular morbidity and mortality,” Dr. Ramon C. Hermida from the University of Vigo, Spain, told Reuters Health by email.

Several earlier studies have shown asleep blood pressure to be a stronger risk factor for CVD events than mean blood pressure or blood pressure at other times of the day. In the new work, online August 10 in theĀ European Heart Journal, Dr. Hermida and colleagues evaluated multiple parameters derived from ambulatory blood pressure monitoring as risk markers of CVD morbidity and mortality. They also investigated whether treatment-induced changes in these parameters reduced CVD risk in their study of more than 18,000 participants in the Hygia Project, a research network established to extend the use of ABPM in primary care.
