Twenty-Four Hour Ambulatory Blood Pressure Monitoring to Evaluate Effects on Blood Pressure of Physical Activity in Hypertensive Patients

2006

OBJECTIVE: Elevated blood pressure is an important risk factor for cardiovascular disease and stroke. Several studies have demonstrated that physical exercise reduces blood pressure levels in hypertensive subjects and improves control of several well-known risk factors for atherosclerosis such as diabetes mellitus, blood lipid profile and obesity. Our group attempted to evaluate if an exercise program based on periodic controlled fast walking sessions would reduce blood pressure levels in hypertensive subjects. DESIGN: We enrolled hypertensive subjects not suffering from obesity (Body Mass Index <30) already under pharmacological therapy; in these subjects we performed a six-week program of…

Metabolic syndrome in subjects with white-coat hypertension: impact on left ventricular structure and function

2007

Some reports have suggested that white-coat hypertension (WCH) is associated with some features of the metabolic syndrome (MetS). These metabolic disturbances, instead of WCH per se, may potentially explain the greater extent of end-organ damage sometimes observed in WCH subjects (WCHs) when compared to normotensive individuals (NTs). The aim of the present cross-sectional study was to compare left ventricular (LV) structure and function in three groups of subjects: WCHs with MetS, WCHs without MetS and NTs. A total of 145 WCHs, 35% of whom had MetS, were enrolled. As controls, 35 NTs were also studied. In all subjects, routine blood chemistry, echocardiographic examination and 24-h ambulat…

Overview of ambulatory blood pressure monitoring in childhood and pregnancy.

2001

Despite the fact that the study and applicability of ambulatory blood pressure in children and pregnant women share characteristics which limit the potential development of knowledge for their use, advances produced in the last few years provided the present knowledge regarding the significance and the potential use of ambulatory blood pressure in children and in the pregnant women. In children ambulatory blood pressure monitoring is useful for the diagnosis of mild hypertensives, assessment of refractory hypertension, therapeutic trials with antihypertensive drugs, and clinical investigation when BP is one of the parameters to be taken into account and/or when subtle BP abnormalities are t…

Vitamin D receptor gene polymorphisms and plasma renin activity in essential hypertensive individuals.

2014

Several studies analyzed 25-hydroxyvitamin D (25[OH]D) and blood pressure (BP) relationship with mixed results. Moreover, a relationship between the risk of hypertension and vitamin D receptor (VDR) gene polymorphisms, FokI and BsmI, was reported. This study was aimed to analyze these relationships in essential hypertensive (EH) patients. Seventy-one EH patients, 18-75 years old, were enrolled. Patients underwent clinical BP, 24-h ambulatory BP monitoring, 25[OH]D and plasma renin activity (PRA) evaluations. FokI and BsmI VDR polymorphisms were analyzed and compared with those of 72 healthy controls. In EH patients, the median 25[OH]D levels were lower than 30 ng ml(-1). We found a signific…

Relationship Between Short-Term Blood Pressure Variability and Subclinical Renal Damage in Essential Hypertensive Patients

2015

The authors aimed to analyze the relationship between subclinical renal damage, defined as the presence of microalbuminuria or an estimated glomerular filtration rate (eGFR) between 30 mL/min/1.73 m(2) and 60 mL/min/1.73 m(2) and short-term blood pressure (BP) variability, assessed as average real variability (ARV), weighted standard deviation (SD) of 24-hour BP, and SD of daytime and nighttime BP. A total of 328 hypertensive patients underwent 24-hour ambulatory BP monitoring, 24-hour albumin excretion rate determination, and eGFR calculation using the Chronic Kidney Disease Epidemiology Collaboration equation. ARV of 24-hour systolic BP (SBP) was significantly higher in patients with subc…

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 ventricular mass (LVM) and the pulsatile (pulse pressure) and steady (mean pressure) components of the blood pressure (BP) curve, 304 young and middle-aged essential hypertensive patients were studied by means of 24-h ambulatory BP monitoring and echocardiography. In the overall study population, both the BP components showed significant correlations with LVM. These correlations were unevenly distributed in the subgroups of subjects younger and in those older than 50 years. While in this latter subgroup, in multivariate analysis, both 24-h mean BP (24-MBP) (beta = 0.27; P = 0.008) and 24-h pulse pressure (24-h PP) (beta = 0.23; P = 0.02) were a…

Impaired exercise tolerance is associated with increased urine albumin excretion in the early stages of essential hypertension

2011

Background: Our aim was to investigate the relationship between impaired exercise capacity and albumin excretion level in the setting of never treated essential hypertension. Design and methods: For this purpose, 338 consecutive essential hypertensives (52 ± 8.5 years, 227 males, office BP = 148.6/96.1 mmHg) performed a negative for myocardial ischemia, maximal treadmill exercise testing and were classified based on the gender specific median value of the amount of metabolic equivalents (METs) achieved (10.1 ml/kg/min for women and 11 ml/kg/min for men) as fit ( n = 177) and unfit ( n = 161). All the participants underwent 24-h ambulatory BP monitoring, complete echocardiographic study inc…

Uncontrolled early morning blood pressure in medicated patients: the ACAMPA study

2002

BACKGROUND A blood pressure surge during the early morning may help to precipitate cardiovascular events. The objective of this study was thus to assess the blood pressure behaviour profile of early morning blood pressure in patients receiving antihypertensive treatment. DESIGN The ACAMPA study is a multi-center, open, prospective, observational study that was carried out by 24 investigators in Spain. METHODS Two hundred and ninety patients with essential hypertension who had been receiving the same antihypertensive treatment for at least 2 months were included in the study. Office blood pressure was measured before taking medication in the morning, and 24-h ambulatory blood pressure monito…

Ambulatory blood pressure during diseases of the kidney

1999

During the last few years there has been a renewal of interest in blood-pressure-induced kidney damage due to a progressive increase in the incidence and prevalence of hypertension and vascular diseases as a cause of end-stage renal disease (ESRD). The need to prevent ESRD demands a continuation of effort to make the early identification of hypertensives who are at risk possible and to provide them with effective antihypertensive therapy. Since ambulatory blood pressure monitoring has been used successfully to assess blood pressure and identify risk markers for cardiovascular diseases, a logical approach would be to use it also to identify the risk markers for ESRD. Higher than normal perce…
