This study evaluated the myocardial strain and aortic elasticity in patients with bicuspid aortic valve (BAV) and then investigated the relation between them. Thirty-nine patients (30 males; mean age 44±19 years; range 6 to 75 years) with BAV were recruited as BAV group, and 29 age- and sex-matched healthy controls (21 males; mean age 42±11 years; range 20 to 71 years) served as control group. Aortic strain, distensibility and stiffness index were derived using M-mode echocardiography. Left ventricular global myocardial strain was acquired with speckle-tracking echocardiography...

BACKGROUND: Evidence suggests that interleukin (IL)-1β is important in the pathogenesis of atherosclerosis and its complications and that inhibiting IL-1β may favorably affect vascular disease progression. OBJECTIVES: The goal of this study was to evaluate the effects of IL-1β inhibition with canakinumab versus placebo on arterial structure and function, determined by magnetic resonance imaging. METHODS: Patients (N = 189) with atherosclerotic disease and either type 2 diabetes mellitus or impaired glucose tolerance were randomized to receive placebo (n = 94) or canakinumab 150 mg monthly (n = 95) for 12 months...

BACKGROUND AND AIM: Decreased vascular reactivity in atherosclerosis was previously shown. In our study, it was aimed to demonstrate the decreased vascular functions in both microvascular and macrovascular tissues and to estimate any correlation between them. METHODS: Twenty-five control outpatients with no coronary artery disease (CAD) history and 26 outpatients with CAD history were enrolled in the study. Local cutaneous post-occlusive reactive hyperemia (PORH) responses after three minutes of brachial occlusion with a pneumatic cuff were recorded noninvasively by a Perimed Periflux 5010 laser Doppler flow system...

BACKGROUND: A new feature of coronary computed tomography angiography (CTA) is to estimate ascending aortic elasticity without additional cost, but its applicable benefit for prehypertension patients is still unclear. The aim of this study is to discuss the characteristic of ascending aortic elasticity for specific prehypertension patients and its risk factors. METHODS: Coronary CTA examinations of 398 participants were performed using a 128 slicer CT scanner. The differences of 3 ascending aortic elasticity related indices, including aortic distensibility (AD), aortic compliance (AC), and aortic stiffness (ASI), and anatomical measurements were analyzed among the normal, prehypertension, and primary hypertension groups...

BACKGROUND AND OBJECTIVES: There is a lack of evidence concerning associations between novel parameters of arterial stiffness as cardiovascular risk markers and traditional structural and functional vascular biomarkers in a population-based Caucasian cohort. We examined these associations in the second follow-up of the Swiss Cohort Study on Air Pollution and Lung and Heart Diseases in Adults (SAPALDIA 3). METHODS: Arterial stiffness was measured oscillometrically by pulse wave analysis to derive the cardio-ankle vascular index (CAVI), brachial-ankle (baPWV) and aortic pulse wave velocity (aPWV), and amplitude of the forward and backward wave...

OBJECTIVE: Preterm birth predisposes to the development of cardiovascular diseases in adulthood. The aim of this study was to characterize elastic properties of the aorta at preschool age and test the hypothesis that prematurity is associated with decreased aortic distensibility and increased stiffness, both of which are predictors of increased cardiovascular risk. APPROACH AND RESULTS: In an observational study of 76 five- to seven-year-old children born at a gestational age <32 weeks and 79 term-born controls, elastic parameters of the ascending and descending abdominal aorta were determined noninvasively by means of M mode echocardiographic tracings and calculated using computerized wall contour analysis...

Aortic root dilatation is associated with increased cardiovascular risk in hypertensive adults. In the young, few data have been published evaluating the cardiovascular organ damage that may be present in patients with aortic dilatation. The objective was to evaluate the prevalence of proximal aorta dilatation, its possible determinants, and its relation with target organ damage in young subjects. The aorta was measured at the level of the sinus of valsalva and at its proximal ascending aorta (pAA) in a total of 177 young subjects (11-35 years)...

To investigate intrinsic vascular abnormalities of the ascending aorta before adulthood in Turner syndrome patients (TS), we compared 25 adolescent TS patients (mean age 14.6 ± 3.4 years) and 16 healthy controls from a university hospital. Blood pressure and other vascular indices were evaluated using echocardiography such as aortic strain, stiffness index, distensibility, and pulse wave velocity. Aortic strain (0.1237 vs. 0.1865, respectively; P = 0.003) and aortic distensibility (0.0049 vs. 0.0081, P = 0...

BACKGROUND: The increased cardiovascular morbidity of adults with late repair of aortic coarctation (CoA) has been well documented. In contrast, successful CoA repair in early childhood has a generally good prognosis, though adverse vascular and ventricular characteristics may be abnormal, which could increase long-term risk. This study sought to perform a comprehensive analysis of aortic elasticity and left ventricular (LV) function in patients with aortic coarctation (CoA) using cardiovascular magnetic resonance (CMR)...

OBJECTIVE: Aim of the study is to evaluate the effect of effect of bariatric surgery on vascular and renal biomarkers in morbidly obese, normotensive, non-diabetic patients. DESIGN AND METHOD: 25 patients (19 women, age 44 ± 11 years, BMI 45 ± 7 kg/mq) were enrolled. A multidistrict vascular assessment was performed before and 12 months after bariatric surgery, including: aortic stiffness (carotid-femoral pulse wave velocity - PWV), endothelial function (flow-mediated dilation - FMD), carotid intima media thickness (cIMT) and distensibility coefficient (DC), and renal hemodynamics by means of renal resistive index (RI) in resting conditions and after sublingual administration of glyceryl trinitrite 25 mcg s...

OBJECTIVE: Proximal aortic function estimated by Magnetic Resonance Imaging (MRI) is booming to assess aortic diseases as stiffness indices have been shown to be independent predictors of cardiovascular events and mortality.Calculation of aortic distensibility (AD) requires MRI aortic strain data, but also local blood pressure (BP). Because of magnetic field limitations, most MRI studies used Brachial Pulse Pressure (bPP) as a surrogate of Central Pulse Pressure (cPP).New devices allow the estimation of cPP from brachial cuff and are compatible with MRI...

OBJECTIVE: The present work aims to test a new optical fibre probe (POFpen) to measure the carotid distension waveform, comparing it with the simultaneously acquired invasive arterial pulses by an intracatheter in the ascending aorta. DESIGN AND METHOD: The optical fibre device detects the pulse wave by placing a reflector at the carotid surface, whose distension movements modulate an applied optical signal that is monitored in reflection. Simultaneous acquisitions of distension carotid pulses with the POFpen and invasive pressure catheter in the aortic root were performed in 19 subjects, with an average age of 71 ± 12 years...

BACKGROUND: Intrauterine growth restriction is associated with arterial hypertension in adulthood; however, the underlying mechanism is unclear. OBJECTIVES: We hypothesized that serum insulin-like growth factor-1 (IGF-1) levels affect central aortic elastic properties and structure in small-for-gestational-age (SGA) infants. METHODS: Eighteen SGA infants and 22 appropriate-for-gestational-age (AGA) infants were enrolled in this study. The serum IGF-1 level within 1 h of birth and abdominal aortic echo parameters at 1 week of age were retrospectively compared...

BACKGROUND AND AIMS: There is increasing evidence linking arterial (mainly aortic) stiffness and type 2 diabetes, a risk factor for arterial stiffness, to cognitive impairment and dementia. However, data on carotid stiffness, which may be especially relevant for cognitive performance, are scarce, and few studies have addressed the interplay between arterial stiffness, type 2 diabetes, and cognitive performance. METHODS: We studied individuals with (n = 197) and without (n = 528) type 2 diabetes, who completed a neuropsychological test battery and underwent applanation tonometry and vascular ultrasound to evaluate aortic (i...

OBJECTIVES: Aortic distensibility and pulse-wave velocity (PWV) are under investigation as parameters by which to evaluate the indication for ascending aorta (AA) replacement. The maximum rate of systolic distension (MRSD) was proposed as a new index of aortic elasticity. The aim of this study was to assess the role of aortic elasticity parameters to predict AA growth rates in patients with AA dilation (AAD). METHODS: Magnetic resonance imaging (MRI) was performed annually in 65 patients with AA dilation (median follow-up 17 months; 25-75th percentile; range 12-30 months)...
