Antihypertensive activity of angiotensin II AT1 receptor antagonists: a systematic review of studies with 24 h ambulatory blood pressure monitoring.
2007
To perform a systematic review of the antihypertensive activity of the angiotensin II AT1 receptor antagonists (ARB).Studies in which blood pressure (BP) was measured using ambulatory BP monitoring for at least 24 h were collected from MEDLINE. Data for each treatment group, ARB, placebo or the drug used for its comparison were obtained from the selected studies. Only studies with a minimum of quality criteria were selected. The final study group contained 36 publications, with a total of 47 patient cohorts receiving ARB in monotherapy, 10 with placebo, 10 with amlodipine, and five with enalapril. The reduction in clinical and ambulatory BP during 24 h, day, night and the last 4-h period fo…
Nocturnal blood pressure and progression to end-stage renal disease or death in nondiabetic chronic kidney disease stages 3 and 4
2010
Objective The objective was to assess the role of office and ambulatory blood pressure (BP) on the development of end-stage renal disease (ESRD) in nondiabetic chronic renal failure. Design and method Seventy-nine patients [mean age 57 (standard deviation 11) years, 47 men, BMI 28 (4), office BP 151 (25)/92 (14) mmHg, estimated glomerular filtration rate 28 (14) ml/min per 1.73 m3] were included. The causes of renal disease were nephrosclerosis (n = 33), glomerulonephritis (n = 19), interstitial (n = 12) and others (n = 15). The average follow-up was 44 months (range 9-72 months). The primary outcome was a composite of death, from any cause, or the development of ESRD that require initiatio…
Impact of metabolic syndrome on left ventricular mass in overweight and obese hypertensive subjects
2007
BACKGROUND: Metabolic syndrome (MS) has been associated with an increased left ventricular (LV) mass in recent reports. Little is known about the association of MS with LV mass (LVM) in overweight and obese individuals. The aim of our study was to investigate the relation between MS and LVM in a population of overweight and obese hypertensive subjects. METHODS: 289 non-diabetic essential hypertensives with a body mass index >25 kg/m2, were enrolled. In all subjects routine blood chemistry, echocardiographic examination and 24-h ambulatory blood pressure monitoring were performed. RESULTS: In the group of overweight patients, participants with MS (n=58), when compared to those without it (n=…
Correlation between hypertrophy and risk of hypertension in congenital solitary functioning kidney
2018
Purpose: Solitary functioning kidney (SFK) may be associated to hypertrophy, hypertension and chronic kidney disease. We evaluated blood pressure (BP) of children with congenital SFK comparing agenesis to multicystic dysplastic kidney (MCDK) and correlated BP profiles with renal dimensions of affected and contralateral kidney. Methods: We compared 40 patients with MCDK, grouped for either treatment options (A: conservative vs B: nephrectomy) or involution time (A1: before 4 years-of-age vs A2: persistence-of-MCDK), to 10 unilateral agenesis (C). Patients were evaluated with ultrasound, scintigraphy, office-ambulatory BP monitoring. Results: Compensatory hypertrophy was demonstrated in most …
Influence of Concurrent Obesity and Low Birth Weight on Blood Pressure Phenotype in Youth
2009
The aim of this study was to assess the impact of obesity and low birth weight on both office and ambulatory blood pressure (BP) values, as well as on aortic-derived parameters in youths. A total of 422 white youths, from 10 to 18 years of age, were included. Subjects were divided into 4 groups according to the presence (234; 55%) or the absence (188; 45%) of obesity and according to low (114; 27%) or normal (308; 73%, birth weight. Spacelabs 90207 was used to measure ambulatory BP during a 24-hour period. SphygmoCor radial/aortic transform software was used to estimate aortic pressure waveform. Office, 24-hour, daytime, and nighttime systolic BP values were significantly higher in those s…
Relationship between birth weight and awake blood pressure in children and adolescents in absence of intrauterine growth retardation.
1996
This study was designed to examine the relationship between birth weight (BW) and ambulatory blood pressure in children and adolescents, born at term in absence of intrauterine growth retardation. Twenty-four hour ambulatory blood pressure monitoring (ABPM) was performed on 332 children (150 boys), aged from 6 to 16 years. Subjects were stratified by BW tertiles and age. ABPM was performed using SpaceLabs 90207 monitor during a regular school day. Blood pressure (BP) was measured every 20 min from 06:00 to 24:00, and thereafter every 30 min. Means of systolic BP (SBP) and diastolic BP (DBP) during 24 h, daytime (08:00 to 22:00), and nighttime (24:00 to 06:00) were calculated. Systolic and d…
Obesity modifies the relationship between ambulatory blood pressure and natriuresis in children
2001
The objective in the present study was to evaluate if obesity beginning in the first two decades of life influences the relationship between ambulatory blood pressure and urinary sodium excretion.Eighty-five obese and 88 non-obese children aged 3-19 years were included in the study. For each subject, a 24h ambulatory blood pressure monitoring and a complete urine collection were simultaneously performed according to the protocols designed. The averages of ambulatory blood pressure and of the urinary excretion rates for sodium, potassium and creatinine were calculated separately for 24-h, awake and sleep periods as defined by a mini-diary.Weight and sodium excretion are directly associated w…
Added impact of obesity and insulin resistance in nocturnal blood pressure elevation in children and adolescents.
2008
The aim of the present study was to analyze the relationship between insulin resistance and the ambulatory blood pressure components in obese children and adolescents. Eighty-seven overweight and obese white children and adolescents of both sexes, of European origin from 6 to 18 years of age (mean age: 10.9±2.7 years), were selected. Obesity was defined on the basis of a threshold body mass index z score >2 (Cole’s least mean square method) and overweight with a body mass index from the 85th to 97th percentile. A validated oscillometric method was used to measure ambulatory BP (Spacelabs 90207) during 24 hours. Fasting glucose and insulin were measured, and the homeostasis model assessm…
Methodology and technology for peripheral and central blood pressure and blood pressure variability measurement: current status and future directions…
2016
Office blood pressure measurement has been the basis for hypertension evaluation for almost a century. However, the evaluation of blood pressure out of the office using ambulatory or self-home monitoring is now strongly recommended for the accurate diagnosis in many, if not all, cases with suspected hypertension. Moreover, there is evidence that the variability of blood pressure might offer prognostic information that is independent of the average blood pressure level. Recently, advancement in technology has provided noninvasive evaluation of central (aortic) blood pressure, which might have attributes that are additive to the conventional brachial blood pressure measurement. This position …
Vascular health assessment of the hypertensive patients (VASOTENS) Registry: rationale, design and methods of an international registry for ambulator…
2015
Ambulatory (A) blood pressure (BP), central BP and pulse wave velocity (PWV) are parameters recommended by hypertension guidelines for estimating BP control and vascular impairment. Recent advances in technology made available devices allowing combined non-invasive estimation of these parameters over the 24-h during ABP monitoring (ABPM). However, at present, there is limited evidence on the usefulness of such an approach for routine hypertension managementWe recently launched an investigator-initiated, international, multicenter, observational, prospective study with the following objectives: • The evaluation of non-invasive ambulatory blood pressure and arterial stiffness estimates (throu…
