ASSOCIATION OF RENAL RESISTIVE INDEX WITH MARKERS OF EXTRARENAL VASCULAR CHANGES IN PATIENTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS
2016
Introduction: Recent data suggest that renal hemodynamic parameters obtained by duplex Doppler sonography, especially the intrarenal resistive index (RRI), may be associated with systemic vascular changes. However, limited and conflicting data exist about the relationship between aortic stiffness and RI in autoimmune diseases, like systemic lupus erythematosus (SLE). Aim: To evaluate the relationship between RRI and arterial stiffness, assessed by aortic pulse wave velocity (aPWV), and between RRI and carotid atherosclerosis, evaluated by intima-media thickness (IMT) measurement in patients with SLE. Methods: In this cross-sectional study, we enrolled 39 SLE subjects (mean age 39 years) tha…
Association of central and peripheral pulse pressure with intermediate cardiovascular phenoytpes
2012
Objective: We assessed the relationship between pulse pressure and intermediate cardiovascular phenotypes in a middle-aged cohort with high prevalence of hypertension. Background: It has been suggested that central pulse pressure (cPP) is a better predictor of cardiovascular outcome than peripheral pulse pressure (pPP), particularly in the elderly. Yet, it is unclear if cPP provides additional prognostic information to pPP in younger individuals. Methods: In 535 individuals we assessed cPP and pPP as well as the intermediate cardiovascular phenotypes pulse wave velocity (PWV; SphygmoCor, Complior, PulsePen), carotid intima-media thickness (C-IMT; carotid ultrasound), left-ventricular mass i…
Isolated, subtle, neurological abnormalities in neurologically and cognitively healthy aging subjects
2015
The aim of this study is to describe the frequency of isolated, subtle, neurological abnormalities (ISNAs) in a large population of neurologically and cognitively healthy subjects and to compare ISNAs to various types of MRI-detected cerebrovascular lesions and subcortical brain atrophy in different age classes. 907 subjects were selected from a large, prospective hospital-based study. At baseline neurological examination, 17 ISNAs were selected. Primitive reflexes were the most common ISNAs (35.8 %), while dysphagia was the most rarely encountered (0.3 %). Measures of small vessel disease, i.e., deep and subcortical white matter hyperintensity and lacunar infarcts as well as subcortical at…
Association between uric acid and renal function in hypertensive patients: which role for systemic vascular involvement?
2016
The role of systemic vascular involvement in mediating the association between serum uric acid (SUA) and renal function in hypertension has not been explored. Main purpose of our study was to investigate whether morphofunctional vascular changes, assessed as carotid intima-media thickness (cIMT) and aortic pulse wave velocity (aPWV), might mediate the association between SUA and renal damage. We enrolled 523 hypertensive subjects with or without chronic kidney disease and divided population into tertiles of SUA based on sex-specific cutoff values. cIMT and aPWV were higher in uppermost SUA-tertile patients when compared to those in the lowest ones (all P < .001). Uricemia strongly correlate…
Relationship between kidney findings and systemic vascular damage in elderly hypertensive patients without overt cardiovascular disease
2017
Few studies have investigated the influence of age on the relationships between systemic vascular damage, kidney dysfunction, and intrarenal hemodynamic changes in patients with hypertension without overt cardiovascular disease. The authors enrolled 126 elderly patients with hypertension (aged ≥65 years) and 350 nonelderly patients with hypertension (aged <65 years). Carotid intima‐media thickness, renal resistive index, and aortic pulse wave velocity were performed in all patients. Elderly patients with hypertension had lower estimated glomerular filtration rates and higher albuminuria, renal resistive index, carotid intima‐media thickness, and aortic pulse wave velocity compared with none…
Subclinical atherosclerosis and fetuin-A plasma levels in essential hypertensive patients
2012
The intima-media thickness (IMT) is considered as a surrogate marker for atherosclerotic disease. The aim of this study was to analyze the relationship of carotid IMT with fetuin-A in patients with essential hypertension (EH) and normal renal function. The plasma levels of fetuin-A, interleukin 6 (IL-6), tumor necrosis factor-α (TNF-α) and the biomarker of oxidative stress 8-iso-PGF2alpha were assayed in samples from 105 untreated EH patients. Carotid IMT measurements were also performed. EH was studied overall and after dividing in EH with IMT ≥ and 0.9 mm (AUC (area under the curve) 0.738, P<0.0001). Our results suggest that in EH, fetuin-A is associated with the IMT independently of oxid…
Endothelial function and serum concentration of toxic metals in frequent consumers of fish.
2014
BACKGROUND:Endothelial dysfunction is involved in the pathogenesis of atherosclerosis. Consumption of fish is associated with reduced cardiovascular risk, but there is paucity of data concerning its effect on endothelial function. Furthermore, investigation of the effects of fish consumption on health must take into account the ingestion of contaminants, including transition metals and some metalloids, which may have unfavorable effects on health, including those on the cardiovascular system. We investigated the association between fish consumption, endothelial function (flow mediated dilation of the brachial artery), and serum concentration of some toxic metals in apparently healthy people…
Task force on 'Early markers of atherosclerosis: influence of age and sex'
2013
Atherosclerosis and its complications are the most important causes of death all over the world, especially in Western countries. Diet habits, modern stress life, smoking, sedentary way of life and an involvement of genetic pattern of individuals lead to a sure degeneration of quality of life increasing the risk of atherosclerosis development. For this reason, the main purpose of actual medicine is to identify all the markers that could allow the physicians to evaluate the first moments of the development of this dangerous pathological process. The aim is to reduce the speed of its evolution, trying to delay indefinitely the risk coming from the morphological alterations of the vessels. 'En…
2013 ESH/ESC Guidelines for the management of arterial hypertension
2013
Because of new evidence on several diagnostic and therapeutic aspects of hypertension, the present guidelines differ in many respects from the previous ones. Some of the most important differences are listed below: 1. Epidemiological data on hypertension and BP control in Europe. 2. Strengthening of the prognostic value of home blood pressure monitoring (HBPM) and of its role for diagnosis and management of hypertension, next to ambulatory blood pressure monitoring (ABPM). 3. Update of the prognostic significance of night-time BP, white-coat hypertension and masked hypertension. 4. Re-emphasis on integration of BP, cardiovascular (CV) risk factors, asymptomatic organ damage (OD) and clinica…
Carotid artery stiffness as an early marker of vascular lesions in children and adolescents with cardiovascular risk factors.
2010
INTRODUCTION AND OBJECTIVES The availability of a noninvasive marker of vascular lesions that enables their detection in the preclinical phase would be of great benefit for cardiovascular disease prevention. The aim of this study was to investigate the usefulness of a range of indices of arterial wall stiffness in the common carotid artery, as derived using high-resolution Doppler ultrasonography, for identifying vascular damage in children with risk factors. METHODS The study involved 99 children (age, 8-16 years) divided into two groups: 65 had cardiovascular risk factors (45 obesity, 20 dyslipidemia) and 34 were controls. Family histories of cardiovascular risk factors and anthropometric…
