BACKGROUND: In the development of hypertensive microvascular remodeling, a relevant role may be played by changes in extracellular matrix proteins. Aim of this study was the to evaluate some extracellular matrix components within the tunica media of subcutaneous small arteries in 9 normotensive subjects and 12 essential hypertensive patients, submitted to a biopsy of subcutaneous fat from the gluteal or the anterior abdominal region. PATIENTS AND METHODS: Subcutaneous small resistance arteries were dissected and mounted on an isometric myograph, and the tunica media to internal lumen ratio was measured...

OBJECTIVE: Carotid-femoral pulse wave velocity (cfPWV) was associated with serum parathyroid hormone (PTH) in untreated Chinese. We investigated in the same cohort whether cfPWV, brachial-ankle (baPWV) and heart-brachial (hbPWV) pulse wave velocity (PWV) were associated with rs6127099 (CYP24A1) and rs4074995 (RGS14). A previously published genome-wide association study demonstrated that each additional copy of the T (rs6127099) or G (rs4074995) allele was associated with a 7% or 3% higher serum PTH, respectively...

BACKGROUND: Endostatin, cleaved from collagen XVIII in the extracellular matrix, is a promising circulating biomarker for cardiovascular damage. It possesses anti-angiogenic and anti-fibrotic functions and has even been suggested to be involved in blood pressure regulation. Less is known if endostatin levels relate to circadian blood pressure patterns. In the present paper we studied the association between circulating levels of endostatin and nocturnal dipping in blood pressure. METHODS: We used the CARDIPP-study, a cohort of middle aged, type 2 diabetics (n = 593, 32% women), with data on both 24-hour and office blood pressure, serum-endostatin, cardiovascular risk factors, and incident major cardiovascular events...

OBJECTIVES: Continuous positive airway pressure (CPAP) improves upper airway obstruction in patients with obstructive sleep apnoea (OSA), who often are overweight-obese. Although it is thought that CPAP improves long-term blood pressure control (BP), the impact of acute and short-term CPAP use on the cardiovascular system in obese patients has not been described in detail. METHODS: Obese patients (body mass index, BMI > 25 kg/m2 ) with OSA were studied awake, supine during incremental CPAP titration (4-20 cmH2 O, +2 cmH2 O/3 mins)...

PURPOSE: Atrial fibrillation (AF) is associated with an increased risk for cardiovascular morbidity and mortality, not entirely explained by thromboembolism. The underlying mechanisms for this association are largely unknown. Similarly, high blood pressure (BP) increases the risk for cardiovascular events. Despite this the interplay between AF and BP is insufficiently studied. The purpose of this study was to examine and quantify the beat-to-beat blood pressure variability in patients with AF in comparison to a control group of patients with sinus rhythm...

PURPOSE: Aldosterone-producing adenoma (APA) is the main curable cause of endocrine hypertension cause of primary aldosteronism (PA) and it is in up to 66% of all cases investigated with adrenal vein sampling (AVS). Mutations in the KCNJ5 potassium channel involve up to 70% of APA and cause the most florid PA phenotypes. The recent finding that macrolide antibiotics specifically inhibit in vitro the altered function of mutated KCNJ5 channels has opened new horizons for the diagnosis and treatment of APA with KCNJ5 mutations in that it can allow identification and target treatment of PA patients harbouring a mutated APA...

PURPOSE: Adequate knowledge on hypertension has been shown to improve awareness, adherence to treatment and control of the disease. We aimed to estimate the health-related knowledge about hypertension among the Portuguese population. MATERIALS AND METHODS: A representative sample of Portuguese-speaking dwellers in mainland Portugal (n = 1624), aged 16 to 79 years, was evaluated through face-to-face interviews conducted using a structured questionnaire. Health literacy was evaluated using the instrument Newest Vital Sign...

PURPOSE: Hypertension is the most important modifiable risk factor for stroke. Few data are available on control of hypertension in younger ischemic stroke survivors. MATERIAL AND METHODS: We assessed clinic and ambulatory blood pressure (BP) measurements in 320 patients aged 15-60 years (mean 48 ± 10) included in the Norwegian Stroke in the Young Study during 3-months follow-up after the index stroke. Controlled hypertension was defined as ambulatory BP <130/80 mmHg...

AIMS: Unattended automated office blood pressure (uAutoOBP) may eliminate white-coat effect. In the present study, we studied its relationships to attended office blood pressure (BP) and ambulatory BP monitoring (ABPM). MATERIAL AND METHODS: Stable treated hypertensive subjects were examined in four Czech academic hypertension centres. uAutoOBP was measured with the BP Tru device; attended BP was measured six times: three times with auscultatory method (AuscOBP) by the physician followed optionally by three oscillometric measurements (OscOBP)...

BACKGROUND: Elevated heart rate (HR) increases cardiovascular morbidity and mortality in hypertension. The impact of beta-blockers on patient prognosis in hypertension is controversial. This study examined the age-related effects of betaxolol on HR, muscle sympathetic nerve activity (MSNA), blood pressure (BP) and sympathovagal balance in untreated males with hypertension and tachycardia. METHODS: Ten young (age 26 ± 1 years) and seven older (age 50 ± 4 years) males underwent measurement of BP, HR, HR variability (Poincare plot) and MSNA before and after 8 weeks treatment with betaxolol at the initial starting dose of 10 mg/day, which was increased to 20 mg/day once daily after 4 weeks in all subjects...

OBJECTIVES: Cerebral white matter lesions (WMLs) are regarded to be subclinical ischemic changes of the cerebral parenchyma. Many previous studies have shown that baseline blood pressure (BP) is one of the most important factors for WMLs, but the relation between exercise BP and WMLs has not been fully evaluated. So, we sought to investigate the relationships between cerebral WMLs and peak exercise BP. METHODS: Brain magnetic resonance imaging scan and treadmill testing were performed simultaneously in 130 consecutive subjects without history of stroke or transient ischemic stroke...

PURPOSE: Population-based studies estimating prevalence's of white-coat, masked and sustained hypertension in non-European adolescents are needed, particularly in developing countries. Aiming to determine these estimates and, additionally identify factors associated to these conditions this study was conducted. MATERIALS AND METHODS: Cross-sectional study with a representative sample of secondary school students from a Brazilian state capital. Office measurements were performed with validated semi-automatic devices...

AIM: Tricuspid regurgitation (TR) with the maximum velocity >2.8m/s has been newly integrated into the diagnostic criteria for left ventricular (LV) diastolic dysfunction. Although the maximum velocity of TR within the normal range (TR < 2.8m/s) is frequently detected in hypertensive patients and is associated with enlarged left atrial (LA) volumes, the influence of TR < 2.8m/s on LV diastolic dysfunction remains unknown in uncomplicated hypertension. METHODS: Echocardiography was performed to assess the mitral annular velocity (e'), E/e', LV mass, and LA phasic volumes and emptying fractions (total, passive, and active) in 100 patients with uncomplicated hypertension with TR within the normal range and in 77 of those without measurable TR...

PURPOSE: This observational study investigated the association between serum osteocalcin level and blood pressure in a Chinese population. MATERIALS AND METHODS: A total of 2241 subjects (909 men and 1,332 women; age, 24-78 years) from Shanghai communities were recruited. Subjects were divided into non-hypertensive and hypertensive groups according to diagnosis of hypertension based on the 1999 World Health Organization-International Society of Hypertension Guidelines...

PURPOSE: Although self-measurement of home blood pressure (HBP) is common in Japan and HBP telemonitoring via the Internet is possible, whether telemonitoring improves HBP control better than conventional practice remains unclear. Furthermore, hypertension care with online communication using telemonitored HBP is feasible, whereas the efficacy and safety of such telemedicine have not been established. We aim to compare traditional care, care with office visits using HBP telemonitoring, and antihypertensive telemedicine based on HBP telemonitoring...
