Optimal systolic and diastolic blood pressure threshold that associated with lower risk of white matter hyperintensity progression

open access: yesFrontiers in Aging Neuroscience, 2023
BackgroundThe optimal control thresholds for systolic blood pressure (SBP) and diastolic blood pressure (DBP) in patients with white matter hyperintensity (WMH) are still unclear.MethodA longitudinal retrospective study of patients with brain magnetic ...

Analysis of short-term blood pressure variability in pheochromocytoma/paraganglioma patients [PDF]

open access: yes, 2019
Data on short-term blood pressure variability (BPV), which is a well-established cardiovascular prognostic tool, in pheochromocytoma and paraganglioma (PPGL) patients is still lack and conflicting.

Accuracy of pulse interval timing in ambulatory blood pressure measurement [PDF]

open access: yes, 2016
Blood pressure (BP) monitors rely on pulse detection. Some blood pressure monitors use pulse timings to analyse pulse interval variability for arrhythmia screening, but this assumes that the pulse interval timings detected from BP cuffs are accurate ...

Time-Dependent Drug Administration in Hypertension and its Effect on Blood Pressure Variability

open access: yesJournal of Interdisciplinary Medicine, 2017
Background: Optimizing blood pressure variability seems to represent a new therapeutic target in the management of hypertension. It is emphasized that scheduling at least one antihypertensive agent at bedtime, has the ability to reduce blood pressure.

Lifestyle modification factors in hypertensive patients: impact on blood pressure variability

open access: yesСучасні медичні технології, 2021
Current guidelines do not suggest considering blood pressure variability in the management of hypertensive patients. At the same time, a sufficient evidence base has been accumulated on the relationship of blood pressure variability with damage to target

BLOOD PRESSURE VARIABILITY AND ARTERIAL STIFFNESS

open access: yesArtery Research, 2011
Blood pressure variability (BPV) is defined by the standard deviation of a given sample of population of normotensive or hypertensive subjects. Recent studies have suggested that this parameter might constitute a cardiovascular risk factor.

Prognostic significance of short-term blood pressure variability in acute stroke [PDF]

open access: yes, 2015
Background and Purpose— Blood pressure variability (BPV) may be an important prognostic factor acutely after stroke. This review investigated the existing evidence for the effect of BPV on outcome after stroke, also considering ...

Metabolically exaggerated cardiac reactions to acute psychological stress: The effects of resting blood pressure status and possible underlying mechanisms [PDF]

open access: yes, 2010
The study aimed to: confirm that acute stress elicits metabolically exaggerated increases in cardiac activity; test whether individuals with elevated resting blood pressure show more exaggerated cardiac reactions to stress than those who are clearly ...
