Ambulatory Blood Pressure Values in the Ongoing Telmisartan Alone and in Combination with Ramipril Global Endpoint Trial (ONTARGET)
2012
In the Ongoing Telmisartan Alone and in Combination with Ramipril Global Endpoint Trial, telmisartan (T; 80 mg daily) and ramipril (R; 10 mg daily) caused similar clinic blood pressure (BP) reductions, with a similar incidence of cardiovascular and renal events. The R+T combination lowered clinic BP somewhat more with no further cardiovascular or renal protection. The aim of this substudy was to see whether these clinic BP changes reflected the changes of 24-hour BP, a BP with a better prognostic value. In 422 patients in whom 24-hour BP monitoring was performed either before or after 6 to 24 months of treatment, demographic and clinical characteristics were similar in the 3 treated groups.…
[OP.7D.07] 24-HOUR CENTRAL BLOOD PRESSURE IS BETTER ASSOCIATED WITH TARGET ORGAN DAMAGE OF HYPERTENSION THAN BRACHIAL BLOOD PRESSURE
2017
Objective: The VASOTENS international, multicenter, observational, non-randomized, prospective study aims at evaluating the impact of 24-hour pulse wave analysis of ambulatory blood pressure (BP) recordings on target organ damage and cardiovascular prognosis of hypertensive patients. In the present analysis of study baseline data we checked whether organ damage of hypertension i) is better associated with 24-hour central than peripheral BP and ii) is related to ambulatory arterial stiffness, estimated by pulse wave velocity (PWV) and augmentation index (AIx). Design and method: In 334 hypertensive patients (mean age 53+/-15, 52% males, 45% treated) we obtained 24-hour ABPMs, echocardiograms…
How common is isolated nocturnal hypertension?
2020
The growing use of methods to measure blood pressure (BP) under everyday life conditions in ‘out-of-office’ settings, through either 24-h ambulatory BP monitoring (ABPM) or home BP monitoring (HBPM), for defining BP status has led to identification of four specific hypertension phenotypes, characterized by variable agreement or disagreement between office BP (OBP) and out-of-office BP: true normotension (normal office and out-of-office BP), sustained hypertension (both elevated office and out-of-office BP), masked hypertension (normal office BP and out-of-office BP), and white-coat hypertension (WCH), when OBP is elevated, but out-of-office BP levels are within normal limits. The term ‘whit…

PREVALENCE OF ARTERIAL HYPERTENSION AND CHARACTERISTICS OF NOCTURNAL BLOOD PRESSURE PROFILE OF ASTHMA PATIENTS ACCORDING TO THERAPY AND SEVERITY OF T…
2020
Background: several studies report an increased risk for asthmatic subjects to develop arterial hypertension and the relationship between these two diseases, frequently co-existing, still has some unclear aspects. Methods: The BADA (blood pressure levels, clinical features and markers of subclinical cardiovascular damage of asthma patients) study is aimed to evaluate the prevalence of the cardiovascular comorbidities of asthma and their impact on the clinical outcome. The main exclusion criteria were the presence of other respiratory diseases, current smoking, any contraindication to ambulatory blood pressure monitoring (ABPM). Results: The overall percentage of asthmatics having also hyper…
Changes of plasma endothelin and growth factor levels, and of left ventricular mass, after chronic AT1-receptor blockade in human hypertension.
1998
The stimulation of autocrine and paracrine factors such as basic fibroblast- (bFGF) and platelet-derived (PDGF) growth factors mediates many of the growth-promoting actions of angiotensin II. The aim of this study was to evaluate the effect of chronic AT1-receptor blockade on plasma endothelin-1 (ET-1) and growth factors levels, and on left ventricular mass, in essential hypertension (EH). The study population consisted of 16 patients with mild-moderate EH, and 25 normotensive controls. In the EH patients under basal conditions, and after 3 and 6 months of chronic therapy with Losartan 50 mg/day, we measured serum levels of ET-1, bFGF and PDGF, and tumor necrosis factor (TNF). At the same t…
Ambulatory Blood Pressure in Clinical Practice: Clinical Relevance of Circadian Rhythm and Nocturnal Dip
2012
Blood pressure (BP) variability and terms like dipper and nondipper are now common in daily practice. Several mechanisms underlie abnormalities in circadian variability. Sympathetic overactivity, reduced sensibility of baroreceptors, volume overload, and primary or secondary autonomic dysfunction are the most important factors related to abnormalities in circadian variability. The level of nighttime BP drop has been related to the absolute level of BP elevation, the global cardiovascular risk, the presence of comorbidities, and the type and time of administration of antihypertensive treatment. The relative importance of circadian variability or nocturnal BP as a prognostic factor raise not …
Response to Timing of Antihypertensive Therapy and Circadian Blood Pressure Pattern
2009
We thank Almirall et al1 for their interest in our article.2 In the present answer to their letter, we provide data from the Spanish Ambulatory Blood Pressure Monitoring Registry regarding clinical differences among patients depending on the time that they received their medication (Table). As shown, several differences were evident among groups, with respect to age, duration of hypertension, prevalence of diabetes mellitus, and history of …
Response to Nondipping in Patients With Hypertension
2009
We thank Ben-Dov and Bursztyn for their interest in our article1 and also for their positive feedback and criticism.2 We would like to try to answer directly to the 3 points raised in their letter. First, is siesta influencing the nocturnal BP dip? In the Spanish ambulatory blood pressure monitoring registry, the daytime period was calculated from the time of wake-up in the morning to the time of going to bed in the evening. However, in our opinion, 2 aspects minimize a possible …
Reproducibility and validity of ambulatory blood pressure monitoring in children.
2002
During the past several years ambulatory blood pressure monitoring (ABPM) has been introduced into the study of hypertension and has become a useful tool in making clinical decisions. The ABPM improves the reproducibility of the estimates of a subject's casual blood pressure (BP) both in normotensive and in hypertensive subjects, independent of age. The advantages of ambulatory BP (ABP) over its office counterpart have been studied in children to observe the relationship between BP measurement and early markers of organ damage. In different groups of subjects that have included normotensives, essential hypertensives, renal transplant recipients, or patients with repair of an aortic coarctat…
