OBJECTIVE: Untrained individuals with exaggerated blood pressure (EBP) responses to graded exercise testing are characterized as having resting dysfunction of the sympathetic and cardiovascular systems. The purpose of this study was to determine the resting cardiovascular state of endurance-trained individuals with EBP through a comparison of normotensive athletes with and without EBP. METHODS: EBP was defined as a maximal systolic blood pressure (SBP) at least 190 mmHg and at least 210 mmHg for women and men respectively, in response to a graded exercise test...

OBJECTIVE: Aortic stiffness and central pressure measurements have become increasingly important for the overall estimation of cardiovascular risk. The aim of this study is to verify whether the presence of stenosis in the carotid arteries due to atherosclerotic plaques may induce a bias in the measurement of carotid-femoral pulse wave velocity (PWV) and in the analysis of central pulse waveform variables assessed by carotid tonometry. METHODS: Eighty-four patients (age: 67...

BACKGROUND: Arterial stiffness is a determinant of cardiovascular disease in end stage renal disease. Hemodialysis patients may develop anti-platelet factor 4/heparin antibody (PF4-H Ab) because of heparin treatment in dialysis. We tested whether PF4-H Ab was associated with progression of arterial stiffness in a 3-year follow-up. METHODS: We enrolled 74 hemodialysis patients and studied their clinical, biochemical and arterial stiffness measurement with brachial-ankle pulse wave velocity (baPWV) over 3 years...

It is unclear whether vascular function is affected similarly in children with sickle cell anaemia (SS) and children with sickle haemoglobin C (SC) disease. Therefore, we compared micro and macrovascular functions in healthy (AA) children, children with SS and SC disease, and assessed their association with physical activity. Participants (24 SS, 22 SC and 16 AA), were compared in terms of 1) thermal hyperaemic response (finger pad warming to 42°C) measured by Laser Doppler techniques, 2) arterial stiffness determined by pulse wave velocity, 3) daily energy expenditure related to moderate and intense physical activities estimated by questionnaire and 4) fitness level, evaluated by the six-minute walk test...

Osteoporosis and cardiovascular disease are worldwide public health issues. Recent evidence indicates a possible role of the canonical Wnt/β-catenin signalling pathway as a common mediator between these two diseases. The aim of the present study was to investigate the relationship between serum concentrations of sclerostin and Dkk1, two extracellular inhibitors of Wnt/β-catenin signalling, with carotid intima-media thickness (CIMT) and with arterial stiffness, evaluated by measuring the pulse wave velocity (PWV) in an ambulatory population of adults...

Postmenopausal women are at increased risk for progression of arteriosclerosis and hypertension. Recent cross-sectional evidence suggests that high normal circulating prolactin levels may accelerate vascular ageing in menopause. Postmenopausal women (n=201) were consecutively recruited from a Menopause Clinic and re-evaluated in at least one follow-up visit within the next 3 years. Baseline circulating prolactin levels were measured while both baseline and follow-up vascular and biochemical measurements were performed...

Children and young adults infected with HIV are at elevated risk for cardiovascular disease (CVD). However, scarce data exist on the utility of non-invasive methods to diagnose subclinical CVD, such as pulse wave velocity (PWV), a non-invasive measure of arterial stiffness. The objectives of this study were to assess the relationship of carotid-femoral PWV with subclinical atherosclerosis measured by carotid intima-media thickness (IMT), compare measurements to healthy controls, and evaluate variables associated with PWV in HIV-infected youth...

BACKGROUND: Endothelial dysfunction and arterial stiffening play major roles in cardiovascular diseases. The critical role for the miR-181 family in vascular inflammation has been documented. Here we tested whether the miR-181 family can influence the pathogenesis of hypertension and vascular stiffening. METHODS AND RESULTS: qPCR data showed a significant decrease in miR-181b expression in the aorta of the older mice. Eight miR-181a1/b1-/- mice and wild types (C57BL6J:WT) were followed weekly for pulse wave velocity (PWV) and blood pressure measurements...

AIM: Although the diastolic flow reversal of the descending aorta has been recognized in patients with aortic regurgitation, its generation without this condition is still unknown. This study was performed to investigate whether flow patterns of the descending thoracic aorta, as measured by echocardiography, can represent invasively measured aortic pulse pressure (APP). METHODS: A total of 100 patients (age, 62.3±11.0 years; men, 62.0%) undergoing invasive coronary angiography (ICA) was analyzed...

Low health literacy is associated with poor clinical outcomes. The relationship between literacy and blood pressure (BP) has been inconsistent. We investigated the determinants of health literacy and the potential relationship between health literacy and hypertension management. We conducted a retrospective cohort trial of 360 hypertensive patients. Scale measurements, physical examination, and laboratory tests were performed based on a standard protocol. To determine factors associated with health literacy, multiple logistic regression analysis was performed and the discriminatory power of the scale score for hypertension control was assessed by the area under the receiver operating curve...

Arterial pulse wave velocity (PWV) depends on blood pressure (BP). Correction of PWV for BP is commonly performed using a statistical approach, requiring a patient cohort. We recently developed a mechanistic, model-predictive approach to assess BP-independent changes in carotid PWV (cPWV) at the level of the individual. The goal of the present study is to compare our novel technique to conventional statistical correction, in the context of anti-cancer therapy using anti-angiogenic drugs (AADs). AADs frequently lead to a PWV increase, but also to hypertension, underlining the need for BP correction of PWV measurements...

Interarm systolic blood pressure difference (IASBPD) can predict cardiovascular disease. To investigate the relationship between IASBPD and cardiovascular disease risk factors, a total of 1426 individuals were studied. Blood pressure was assessed simultaneously and IASBPD was expressed as the absolute difference value (|R-L|). Cardiovascular disease risk factors were compared between the high IASBPD group (IASBPD ≥10 mm Hg) and the normal IASBPD group (IASBPD <10 mm Hg). An increased prevalence of hypertension, body mass index, and systolic and diastolic blood pressure were observed in the high IASBPD group (P<...

The risk for diastolic dysfunction increases with advancing age. Regular exercise training ameliorates age-related diastolic dysfunction; however, the underlying mechanisms have not been identified. We investigated whether 1) microvascular dysfunction contributes to the development of age-related diastolic dysfunction, and 2) initiation of late-life exercise training reverses age-related diastolic and microvascular dysfunction. Young and old rats underwent 10 weeks of exercise training or remained as sedentary, cage-controls...
