Relationship between muscle sympathetic nerve activity and diurnal blood pressure profile.
The physiological mechanisms mediating the variability and diurnal rhythm of blood pressure are unclear. We tested the hypothesis that resting sympathetic activity is linked to the variability characteristics and 24-hour profile of ambulatory blood pressure measurements. We evaluated the relationship between muscle sympathetic nerve activity (MSNA) and the level, variability, and nocturnal fall...
متن کاملImpaired diurnal blood pressure variation and all-cause mortality.
BACKGROUND Most healthy people exhibit a decrease in systolic blood pressure (SBP) at night. A drop of <10% from mean daytime values, "non-dipping," is associated with kidney disease and cardiovascular events. We hypothesized that non-dipping would predict all-cause mortality. METHODS Consecutive patients referred for ambulatory blood pressure (BP) monitoring at the Cleveland Clinic between 1...
متن کاملDiurnal blood pressure variation in progressive autonomic failure.
To investigate the role of the autonomic nervous system (ANS) in the generation of the circadian blood pressure (BP) variation, the degree of impairment of the ANS was related to the results of ambulatory BP recordings in 212 patients with progressive autonomic failure due to familial amyloid polyneuropathy. On the basis of BP and/or heart rate (HR) responses to the Valsalva maneuver, 60 degree...
متن کاملImprovement of Diurnal Blood Pressure Variation by Azilsartan
Background Azilsartan is an angiotensin II receptor blocker with a potent antihypertensive effect. Methods In a multicenter, prospective, open-label study, 265 patients with poor blood pressure control despite treatment with other angiotensin II receptor blockers were switched to 20 mg/day of azilsartan (patients on standard dosages) or 40 mg/day of azilsartan (patients on high dosages). Re...
متن کاملAmbulatory physical activity as a determinant of diurnal blood pressure variation.
There are reports that indicate that diurnal blood pressure (BP) variation, in addition to high BP per se, is related to target organ damage and the incidence of cardiovascular events. However, the determinants of diurnal BP variation are not adequately understood. We used actigraphy and ambulatory BP monitoring to study the diurnal variation of BP and physical activity in 160 adults. Within in...
