Resting Electrocardiogram and Blood Pressure in Young Endurance and Nonendurance Athletes and Nonathletes.
2020
Context Much information is available on electrocardiogram (ECG) and blood pressure (BP) changes in senior athletes. However, corresponding data on adolescent athletes are scarce. Objective To study the differences in resting ECG and BP values among adolescent endurance athletes, nonendurance athletes, and nonathletes. Design Cross-sectional study. Setting A total of 154 youth sports clubs in Finland and 100 secondary schools for comparison data. Patients or Other Participants We recruited young athletes (n = 410) aged 14 to 16 years in 10 popular sport disciplines, including winter and summer as well as team and individual sports, and categorized them as endurance or nonendurance sports. …
Factors related to quality of ambulatory blood pressure monitoring in a pediatric population.
1999
To assess the factors related to the quality of ambulatory blood pressure monitoring in a pediatric population, we performed 24-h ambulatory blood pressure monitorings on 333 unselected children aged 3 to 18 years using a Spacelabs 90207 monitor. For each individual, the percentages of valid measurements (ratio between valid and total number of measurements, 76.4% +/-15.6%) and of successful measurements (percentage of valid preset measurements, 89.8% +/- 11.5%) were calculated. Two hundred eighty-one (84.1%) monitorings had a successful measurement rate of >80%. Two hundred thirteen (64%) were of excellent quality, as defined by the percentage of successful measurements being higher than o…
Blood pressure and pulse wave velocity values in the institutionalized elderly aged 80 and over: baseline of the PARTAGE study.
2009
The aim of the longitudinal study PARTAGE (predictive values of blood pressure and arterial stiffness in institutionalized very aged population) was to determine the predictive value of blood pressure (BP) and arterial stiffness for overall mortality, major cardiovascular events and cognitive decline in a large population of institutionalized patients aged 80 and over. In the study herein, we present the baseline data values of this study.A total of 1130 patients were recruited (878 women), living in French and Italian nursing homes. Clinical and 3-day self-measurements of BP were conducted. Aortic and upper limb pulse wave velocity were obtained using a PulsePen tonometer.Of this populatio…
Impact of the metabolic syndrome on total arterial compliance in essential hypertension patients.
2007
The aim of the study was to cross-sectionally analyze, in a group of essential hypertension patients without diabetes mellitus, the influence of the metabolic syndrome (MS) on the stroke volume index to pulse pressure (SVi/PP) ratio, a measure of total arterial compliance. A total of 528 essential hypertension patients, aged 18 to 72 years, free from cardiovascular and renal disease (41% of whom had MS) were enrolled. All participants underwent routine blood chemistry, echocardiographic examination, and 3 blood pressure measurements at the end of echocardiographic examination. When compared with participants who did not have MS, hypertensive patients with MS exhibited lower SVi/PP ratio (0.…
Remote estimation of blood pulse pressure via temporal tracking of reflected secondary speckles pattern
2011
We present a novel technique for remote noncontact blood pulse pressure measurement. It is based on tracking both temporal and amplitude changes of reflected secondary speckle produced in human skin when illuminated by a laser beam. The implemented technique extracts the difference between the systolic and the diastolic blood pressure. Experimental results are presented showing good agreement when compared with conventional measurement methods.
SYSTEMIC ARTERIAL CHANGES AND PULSE PRESSURE: DIFFERENT IMPACT ON RENAL HAEMODYNAMICS IN HYPERTENSIVE PATIENTS.
2015
Objective: Renal resistance index (RRI) is used for kidney disease detection and prognosis, but it also appears a good indicator of systemic vascular changes in hypertensive subjects. Structural atherosclerotic damage, arterial stiffness and pulse pressure may interact each other, and the relationship between intrarenal haemodynamics and systemic vascular alterations has been widely investigated. However, the independent impact of all these parameters on renal haemodynamics and the mechanisms by which they affect renal vasculature remain to be clarified. Design and method: We enrolled 463 hypertensive patients (30–70 years) with normal renal function (group 0; n = 280) and with chronic kidn…
Relationship of choroidal thickness with pulsatile hemodynamics in essential hypertensive patients
2021
Controversy exists about the association of choroidal thickness (CTh) with blood pressure (BP) values. There is some evidence suggesting that central hemodynamics changes are associated with microvascular disease. Our study was aimed to assess the relationships between CTh and clinic and 24-h BP and between CTh and estimated 24-h aortic pulse pressure (aPP), 24-h aortic systolic BP (aSBP), and 24-h aortic augmentation index (aAIx) in a group of hypertensive patients. We enrolled 158 hypertensive subjects (mean age 48 ± 13 years) all of which underwent evaluation of the choroidal district by Swept-Source optical coherence tomography (SS-OCT) and 24-h BP monitoring, in order to measure periph…

Pulsatile and steady 24-h blood pressure components as determinants of left ventricular mass in young and middle-aged essential hypertensives
2003
In order to explore the relations between left ventricularmass (LVM) and the pulsatile (pulse pressure) andsteady (mean pressure) components of the bloodpressure (BP) curve, 304 young and middle-agedessential hypertensive patients were studied by meansof 24-h ambulatory BP monitoring and echocardio-graphy. In the overall study population, both the BPcomponents showed significant correlations with LVM.These correlations were unevenly distributed in thesubgroups of subjects younger and in those older than50 years. While in this latter subgroup, in multivariateanalysis, both 24-h mean BP (24-MBP) (b¼0.27;P¼0.008) and 24-h pulse pressure (24-h PP) (b¼0.23;P¼0.02) were associated with LVM, in th…
