Intraoperative hypotension is associated with significant postoperative complicationsIntraoperative hypotension has been defined relative to preinduction blood pressureBlood pressure varies during the day, and the relationship between preinduction blood pressure and usual blood pressure over 24 h is incompletely describedSimilarly the relationship between low blood pressure intraoperatively and 24-h usual blood pressure is unknown WHAT THIS ARTICLE TELLS US THAT IS NEW: There is a poor correlation between p...
Continuous beat-to-beat blood pressure monitoring permits the rapid detection of blood pressure fluctuations for cardiovascular reflex testing and clinical haemodynamic monitoring. In adults, this can be achieved noninvasively with high accuracy, using finger blood pressure monitoring with volume clamp photoplethysmography. However, data are lacking on the validity of finger blood pressure monitoring in children compared to the gold standard - invasive intra-arterial blood pressure monitoring.
Continuous blood pressure monitoring is essential in the management of patients in critical conditions, as well as those under anesthesia. However, continuous blood pressure monitoring requires insertion of a catheter into the radial artery. Thus, continuous noninvasive arterial blood pressure monitoring would be ideal.
From April to October 2018, we implemented a blood pressure measurement quality improvement project at our Hypertension Center. We aimed to compare blood pressure measured using routine, non-standardized office blood pressure and Systolic Blood Pressure Intervention Trial-like automated office blood pressure protocols.
The aim of our study was to establish if 48-hour ambulatory blood pressure monitoring (ABPM) is more reliable than 24-hour monitoring in order to reduce the impact of external factors on blood pressure (BP) in children.
Prevalence of arterial hypertension is up to 30-40% in epidemiological studies, it increases with aging and affects the cardiovascular risk. Essential form of hypertension is the most frequent; however, 5-10% of patients are affected by a specific and potentially reversible cause of increased blood pressure levels, called secondary hypertension. In general, all patients with young onset-age (
The ASINPHAR@2action project aims at raising awareness to arterial stiffness (AS) and early vascular aging (EVA) through a community pharmacy-based intervention. This preliminary analysis is focused on the analysis of the proportion of participants with increased AS and the identification of its main determinants. We performed an observational cross-sectional study of participants enrolled in 11 community pharmacies in Portugal, between April and November 2017. Blood pressure (BP) and arterial function para...
The efficacy and tolerability of intensive blood pressure lowering may vary by pulse pressure (systolic minus diastolic blood pressure).
Background Exaggerated blood pressure response during exercise predicts future hypertension and cardiovascular events in general population and different patients groups. However, its clinical and prognostic implications in patients with aortic stenosis have not been previously evaluated. Methods and Results We retrospectively studied 301 patients with moderate to severe asymptomatic aortic stenosis (aged 65±12 years) who underwent echocardiography and a modified Bruce exercise treadmill test. An exaggera...
As an alternative to ambulatory 24-h blood pressure monitors, the continuous, non-invasive blood pressure recording using pulse transit time (PTT) was compared with both oscillometric and intra-arterial measurement.
Arterial hypertension remains the world's leading mortality risk factor and despite overwhelming evidence that blood pressure-lowering strategies greatly reduce the cardiovascular risk, a substantial proportion of hypertensive individuals worldwide fail to achieve an optimal blood pressure control under treatment. Among the causes responsible for the gap existing between blood pressure lowering potential of the different antihypertensive treatments and real-life practice is the presence of drug-induced hype...
Home blood pressure monitoring (HBPM) is cited as an effective approach for improving blood pressure control. The objective of this study was to determine the effectiveness of HBPM combined with a health education session in reducing blood pressure and improving medication adherence among adults with hypertension.
There is evidence that choroidal blood flow (ChBF) is regulated in a complex way during changes in ocular perfusion pressure (OPP). We hypothesized that ChBF regulates better in response to changes in mean arterial pressure (MAP) than in intraocular pressure (IOP).
Neuronal blood pressure control is mediated by the autonomic nervous system. In this article, physiological and pathophysiological mechanisms will be recapitulated. Blood pressure regulation aims at maintaining adequate cardiac output and a sufficient perfusion pressure for the organs. In glaucoma, ocular perfusion pressure is defined as the difference between systemic blood pressure and intraocular pressure and is crucial for the supply of the optic nerve. Patients who suffer from normal-tension glaucoma a...
The aim of this study was to investigate whether additional volume reduction by ultrafiltration can improve blood pressure in patients with intradialytic hypertension (IDH) defined as at least 10 mmHg systolic blood pressure (SBP) rise during hemodialysis.
Asymptomatic blood pressure elevation is common in the inpatient setting. National guidelines recommend treating with oral agents to slowly decrease blood pressure; however, many clinicians use intravenous antihypertensive medications, which can lead to unpredictable changes in blood pressure.
Blood flow restriction training using a practical (non-pneumatic) elastic-cuff has recently increased in popularity. However, a criticism of this method is that the pressure applied and the amount of blood flow restriction induced is unknown. The aim was to quantify blood flow following the application of an elastic-cuff and compare that to what is observed using a more traditional pressurized nylon-cuff. Thirty-five young participants (16 men and 19 women) visited the laboratory once for testing. In a rand...
Blood pressure management in the operating rooms (OR) and intensive care units (ICU) frequently involves manually titrated vasopressor therapy to an optimal range of mean arterial pressure (MAP). Ideally, changes in vasopressor infusion rates have to quickly follow variations in blood pressure measurements. However, such a tightly controlled feedback loop is difficult to achieve. Few studies have examined blood pressure control when vasopressor therapy is administered manually in OR and ICU patients. We ext...
This study aimed to compare the venous acid-base status of healthy awake versus anesthetized Magellanic penguins (). Ten nonanesthetized penguins were manually restrained, and a venous blood sample was collected. Six of these penguins were anesthetized by 2% isoflurane and, after an anesthetic stabilization period, both venous and arterial blood samples were simultaneously withdrawn. Using an i-STAT analyzer, partial pressure of carbon dioxide (PCO), partial pressure of oxygen (PO), pH, standard bicarbonate...
Cardiovascular health declines with age, increasing the risk of hypertension and elevated heart rate in middle and old age. Here, we used multivariate techniques to investigate the associations between cardiovascular health (diastolic blood pressure, systolic blood pressure, and heart rate) and white matter macrostructure (lesion volume and number) and microstructure (as measured by diffusion-weighted imaging) in the cross-sectional, population-based Cam-CAN cohort (N = 667, aged 18-88). We found that card...
The 2017 American hypertension guidelines (ACC/AHA) define a blood pressure measurement (BPM) procedure which differs from the Canadian Hypertension Education Program Guidelines (CHEP). We studied the impact of the BPM procedure on arterial hypertension (AHT) prevalence rate.
3D pseudocontinuous arterial spin labeling (pCASL) with a single post-labeling delay time is commonly used to measure cerebral blood flow (CBF). Multi-phase pCASL has been developed to simultaneously estimate CBF and arterial transit time (ATT).
Aging reduces cerebral blood flow (CBF) while mean arterial pressure (MAP) becomes elevated. According to 'the selfish brain' hypothesis of hypertension, a reduction in vertebral artery blood flow (VA) leads to increased sympathetic activity and thus increases MAP. In twenty-two young (24 ± 3 years; mean ± SD) and eleven elderly (70 ± 5 years) normotensive men duplex ultrasound evaluated whether the age-related reduction in CBF affects VA more than internal carotid artery (ICA) blood flow. Pulse-contour ...
Microalbuminuria is a common early hypertension-mediated organ damage, which correlates with the overall cardiovascular risk and development of end-stage renal damage. Lately, blood pressure variability has shown an additive value over traditional BP measurement in prediction of cardiovascular and renal involvement.
