Feasibility of cuff-free measurement of systolic and diastolic arterial blood pressure

2011

We validated a prototype cuff-free device for noninvasive estimation of blood pressure (BP). The system assumed a linear relation between BP values and the inverse of arterial blood pulse transit time, measured as time interval between the R wave on the electrocardiograph and the onset of the peripheral pulse wave on a finger plethysmogram. Thirty-three healthy subjects were analyzed at rest and during increasing stress exercise. To estimate subject-specific linear model parameters, the system was calibrated ad personam with reference to BP measures obtained by a cuff sphygmomanometer. High correlation values (R2= 0.89 and 0.78 for systolic and diastolic BP, respectively) and differences co…

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…

Increase in Nocturnal Blood Pressure and Progression to Microalbuminuria in Type 1 Diabetes

2002

Patients with type 1 diabetes mellitus and microalbuminuria often have elevated blood pressure while they are asleep, but it is not known whether the elevation develops concomitantly with microalbuminuria or precedes it.We monitored 75 adolescents and young adults who had had type 1 diabetes with normal urinary albumin excretion and blood pressure for more than five years. Ambulatory blood-pressure monitoring was used to assess blood pressure at the initial evaluation and about two years later, at which time all subjects had normal urinary albumin excretion. Subsequently, subjects were monitored for the development of microalbuminuria.Microalbuminuria developed in 14 subjects, whereas the o…

C-reactive protein and intercellular adhesion molecule-1 are stronger predictors of oxidant stress than blood pressure in established hypertension

2007

Oxidant stress is implicated in the pathogenesis of atherosclerosis in cardiovascular diseases. Our aim was to test oxidative stress, as 8-iso-prostaglandin F2alpha (8-iso-PGF2alpha), and its relationship with inflammation markers C-reactive protein (CRP) and tumour necrosis factor-alpha (TNFalpha), and endothelial activation assayed as soluble intercellular adhesion molecule (ICAM)-1 and vascular cell adhesion molecule (VCAM)-1 in essential hypertension.In 216 essential hypertensive patients and 55 healthy control individuals, plasma levels of high-sensitivity CRP and TNFalpha, 8-iso-PGF2alpha, ICAM-1 and VCAM-1 were measured in basal conditions. Moreover, basal and 24-h ambulatory blood p…

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…

Influence of the metabolic syndrome on aortic stiffness in never treated hypertensive patients

2004

Summary Background and aim Metabolic syndrome (MS) carries an increased risk for cardiovascular events and there is a growing awareness that large artery stiffening is a powerful predictor of cardiovascular morbidity and mortality. Little is known about the relationship of MS with aortic stiffness. The aim of our study was to analyze, in patients with essential hypertension, the influence of MS, defined according to the criteria proposed by the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (NCEP-ATP III), on carotid–femoral pulse wave velocity (PWV), a measure of aortic stiffness. Methods N…

European society of hypertension position paper on ambulatory blood pressure monitoring

2013

Ambulatory blood pressure monitoring (ABPM) is being used increasingly in both clinical practice and hypertension research. Although there are many guidelines that emphasize the indications for ABPM, there is no comprehensive guideline dealing with all aspects of the technique. It was agreed at a consensus meeting on ABPM in Milan in 2011 that the 34 attendees should prepare a comprehensive position paper on the scientific evidence for ABPM.This position paper considers the historical background, the advantages and limitations of ABPM, the threshold levels for practice, and the cost-effectiveness of the technique. It examines the need for selecting an appropriate device, the accuracy of dev…

Home blood pressure control is low during the critical morning hours in patients with hypertension: the SURGE observational study

2011

Background. The morning blood pressure (BP) surge is associated with a peak increase in vascular events. Objective. The aim of this observational study was to evaluate morning BP control in treated hypertensive patients using home BP (HBP) monitoring and to compare these findings with clinic BP control. Methods. Clinic BP was measured twice during a 2-week period, prior to medication. Seated HBP was measured, using a BHS-validated device, three times per day over a 2-week period. Assessments included morning (06:00–11:59), lunchtime (12:00–14:00) and evening (18:00–22:00) HBP control (all <135/85 mmHg) and clinic BP (<140/90 mmHg) control. Results. A total of 15 618 patients were assessed. …

Self-blood pressure monitoring as a tool to increase hypertension awareness, adherence to antihypertensive therapy, and blood pressure control

2019

For many years, casual blood pressure (BP) taken by a sphygmomanometer in the clinic or at the physician's office has been used as the standard method for diagnosing hypertension. Even if such measurement has been the cornerstone on which our understanding of the consequences of hypertension is based, there is a huge and very consistent body of evidence indicating that casual measurements of BP may provide a very unreliable index for the evaluation of hypertension because of their variability. The two alternative ways of measuring BP that have been most commonly used are measurements made at home by the patient himself (home or self‐BP monitoring—SBPM) and measurements by ambulatory blood p…
