BACKGROUND/OBJECTIVE: Takayasu arteritis (TA) is characterized by extensive aortic, large and midsize arterial wall inflammation. The aim of this study was to assess the morphological and elastic properties of the aorta and large arteries and the impact on left ventricular (LV) mechanics in children with TA. METHODS: Seven pediatric TA patients (6 female patients, 13.8 ± 3.2 years) were assessed with magnetic resonance imaging, vascular ultrasound, applanation tonometry, and echocardiography from February 2015 until July 2017 and compared with 7 age- and sex-matched controls...

High dietary sodium intake can lead to hypertension and increased incidence of cardiovascular disease. We sought to determine the effect of short-term dietary sodium loading on central blood pressure and arterial stiffness in young (YG; 22-40 years) and middle-aged (MA; 41-60 years) normotensive adults. YG (n = 49; age: 27 ± 1 years) and MA (n = 36; age: 52 ± 1 years) subjects were randomized, in a cross-over design, to 7 days of low-sodium (LS; 20 mmol/d) or high-sodium (HS; 300 mmol/d) diet...

Arterial stiffness and cardiac function are important predictors of cardiovascular events in patients with hypertension, even with adequate blood pressure (BP) control. We evaluated whether a direct renin inhibitor, aliskiren, reduces arterial stiffness and modulates left ventricular function compared with a diuretic, hydrochlorothiazide, in elderly hypertensive patients. Twenty-one hypertensive patients [67 ± 14 (SD) yr] were randomly assigned to receive 6-mo aliskiren (n = 11) or hydrochlorothiazide (n = 10)-based therapy...

OBJECTIVE: Reducing prolonged sitting at work has been recommended by an expert panel, but whether intermittent standing improves vascular health is unclear. We aimed to test whether using a sit-stand desk could reduce blood pressure (BP) and pulse wave velocity (PWV) during a simulated workday. METHODS: Overweight/obese adults with pre-to-Stage 1 hypertension completed a randomized crossover study with two simulated workday conditions: STAND-SIT (alternating standing and sitting condition every 30 min) and SIT (continuous sitting condition)...

BACKGROUND: The effectiveness of radial access (RA) in ST-elevation myocardial infarction (STEMI) has been predominantly established in primary percutaneous coronary intervention (pPCI) with limited exploration of this issue in the early postfibrinolytic patient. The purpose of this study was to compare the effectiveness and safety of RA versus femoral (FA) access in STEMI undergoing either a pharmacoinvasive (PI) strategy or pPCI. METHODS AND RESULTS: Within STrategic Reperfusion Early After Myocardial Infarction (STREAM), we evaluated the relationship between arterial access site and primary outcome (30-day composite of death, shock, congestive heart failure, or reinfarction) and major bleeding according to the treatment strategy received...

INTRODUCTION: The etiology of the end-stage renal disease (ESRD) and the hydration status may be involved in the arterial stiffening process observed in hemodialyzed patients. The ratio between carotid-femoral and carotid-radial pulse wave velocity (PWV ratio) was recently proposed to characterize the patient-specific stiffening process. AIMS: to analyze: (1) the PWV-ratio in healthy and hemodialyzed subjects, analyzing potential changes associated to etiologies of the ESRD, (2) the PWV-ratio and hydration status using multiple-frequency bioimpedance and, (3) the effects of hemodialysis on PWV-ratio in a 5-year follow-up...

Percutaneous treatment of subclavian artery stenosis or occlusion has become more popular compared with surgical correction. We compared the early and late results of subclavian artery stenting with bilateral or single transradial access. From 2010 to 2015, we recruited 54 consecutive patients. In 35 cases, we used bilateral access, and in 19 cases, ipsilateral single access was used. Left subclavian artery was the culprit vessel in 72% of cases. There were more chronic total occlusions in the bilateral group (77% vs 21%, p = 0...

Central blood pressure (BP) can be assessed noninvasively based on radial tonometry and may potentially be a better predictor of clinical outcome than brachial BP. However, the validity of noninvasively obtained estimates has never been examined in patients with chronic kidney disease (CKD). Here we compared invasive aortic systolic BP (SBP) with estimated central SBP obtained by radial artery tonometry and examined the influence of renal function and arterial stiffness on this relationship. We evaluated 83 patients with stage 3 to 5 CKD (mean estimated glomerular filtration rate [eGFR] 30 ml/min/1...

BACKGROUND: A central-to-radial arterial pressure gradient may occur after cardiopulmonary bypass (CPB), which, in some patients, may last for a prolonged time after CPB. Whenever there is a pressure gradient, the radial artery pressure measure may underestimate a more centrally measured systemic pressure, which may result in a misguided therapeutic strategy. It is clinically important to identify the risk factors that may predict the appearance of a central-to-radial pressure gradient, because more central sites of measurements might then be considered to monitor systemic arterial pressure in high-risk patients...

OBJECTIVE: The loss of physiological stiffness mismatch between aorta and peripheral arteries was strongly and independently associated with increased mortality in adult dialysis population. The aim of the study was to evaluate if the reversal of arterial stiffness mismatch was present in pre-dialysis patients with chronic kidney disease (CKD). DESIGN AND METHOD: The aortic-brachial arterial stiffness mismatch (pulse wave velocity (PWV ratio) were assessed using carotid-femoral PWV divided by carotid-radial PWV in 112 adult treated hypertensive CKD patients: 54 - with CKD IIIa (age 59,5 ± 8,4 years, male 46,3%, brachial blood pressure (BP) 149,6 ± 10,3/85,8 ± 9,8 mmHg), 35 - with CKD IIIb (age 60,2 ± 7,8 years, male 45,7%, BP 152,5 ± 12,5/86,4 ± 10,2 mmHg) and 23 with CKD IV (age 57,3 ± 10,2, male 43,4%, BP 156,1 ± 14,3/92,8 ± 12,4 mmHg)...

Cardiac catheterization has been increasingly utilized to evaluate coronary artery disease in patients with end stage liver disease (ESLD). It is known in other populations that radial access reduces access site complications;however, there is a paucity of data in ESLD patients. We investigated vascular and bleeding complications rates between trans-femoral and trans-radial cardiac catheterizations in this high risk population. In this retrospective cohort study, three hundred and thirty four ESLD patients were identified between August 2004 and December 2012 who had undergone trans-femoral (femoral group) or trans-radial (radial group) cardiac catheterizations at our institution...

BACKGROUND: Elevated central pressures and arterial stiffness are associated with increased peripheral resistance and higher sympathetic nervous system activity. Additionally, consumption of a meal is known to be sympathoexcitatory. However, the acute effects of a meal on aortic wave reflection and stiffness are unknown. Therefore, we tested the hypothesis that aortic wave reflection and stiffness would increase after a meal. METHODS: We examined these effects using high-fidelity radial arterial pressure waveforms and carotid-femoral pulse wave velocity measured noninvasively by applanation tonometry before and 60 and 180 minutes after ingestion of a liquid mixed meal (Ensure; 40% of daily energy expenditure) in 17 healthy adults (9 men/8 women; aged 29 ± 2 years)...

BACKGROUND AND AIMS: Recent studies have reported early atherosclerosis in patients with inflammatory bowel disease (IBD). In these patients, the chronic low-grade inflammation may predispose to vascular remodelling and arterial stiffening. We aimed at studying arterial stiffness in IBD patients. METHODS: Thirty-two IBD patients without cardiovascular risk factors and 32 matched controls were enrolled (age 19-49 years). SphygmoCor device (AtCor Medical, Sydney, Australia) was used to measure carotid-femoral and carotid-radial (muscular artery) pulse wave velocity (PWV), augmentation index and central blood pressure...

OBJECTIVE: To investigate whether radial augmentation index (AI) associates with cardiovascular risk as well as arterial stiffness. METHODS: A total of 4985 subjects, 2417 men and 2568 women, aged 18 - 96 (50.9 ± 14.7) years, were recruited. AI was measured in the left radial artery using tonometry Colin HEM-9000AI. Carotid-femoral PWV (CFPWV) and carotid-radial PWV (CRPWV) were examined by automatic pulse wave velocity (PWV) measuring system. Framingham risk score and Chinese ischemic cardiovascular disease risk score were applied upon subjects without cardiovascular disease to calculate individual cardiovascular risk respectively...

BACKGROUND: Transradial access for coronary intervention is associated with reduced access complications compared with transfemoral. Transradial access for renal artery intervention has been less well studied. Safety compared with transfemoral access is undetermined. METHODS AND RESULTS: We evaluated the feasibility of transradial renal intervention (n = 11 patients) and compared safety parameters with a matched group of transfemoral controls (n = 44). All transradial interventions were successful with no complications...

OBJECTIVE: Patients with primary hyperparathyroidism (pHPT) are at increased risk of cardiovascular mortality. We investigated whether aortic stiffness, an early marker of arteriosclerosis and a strong predictor of cardiovascular risk, is increased in pHPT, and whether it improves after parathyroidectomy. METHODS: Twenty-four patients with mild pHPT (age 56 ± 10 years, blood pressure 136/85 mmHg, serum calcium 2.55-3.00 mmol/L) and 48 control subjects individually matched with cases by age, sex and blood pressure underwent aortic (carotid-femoral) and upper-limb (carotid-radial) pulse wave velocity (PWV) determination by applanation tonometry in a case-control study...

BACKGROUND/OBJECTIVES: Pre-eclampsia (PE) is associated with profound changes in the maternal cardiovascular system. The aim of the present study was to assess whether alterations in the maternal arterial stiffness precede the onset of PE in at risk women. METHODOLOGY/PRINCIPAL FINDINGS: This was a cross sectional study involving 70 pregnant women with normal and 70 women with abnormal uterine artery Doppler examination at 22-24 weeks of gestation. All women had their arterial stiffness (augmentation index and pulse wave velocity of the carotid-femoral and carotid-radial parts of the arterial tree) assessed by applanation tonometry in the second trimester of pregnancy, at the time of the uterine artery Doppler imaging...
