The renal resistive index: is it a misnomer?

2015

Progress in digital ultrasound technology and diffusion of Doppler ultrasound evaluation of the kidney enable a widespread non-invasive evaluation of renal haemodynamics. Initially most attention has been paid to the study of extraparenchymal renal arteries, mainly to detect renovascular disease. However, this approach has low reproducibility and accuracy. Therefore, interest has gradually moved towards the duplex evaluation of intrarenal anatomy, where the best and most reliable signals are obtained from the large segmental or interlobar arteries that run directly towards the transducer. Among the sonographic parameters used in the last decade, great emphasis has been placed on the intrare…

[OP.2D.05] RELATIONSHIP OF OXIDATIVE STRESS WITH CARDIAC HYPERTROPHY IN HYPERTENSIVE PATIENTS

2016

OBJECTIVE: Left ventricular hypertrophy is common in hypertensive patients. In these subjects increased oxidative stress has been observed. Our aim was to evaluate the association of biomarkers of both oxidative stress and inflammation with markers of cardiovascular damage in a large group of hypertensives with different stages of renal function. DESIGN AND METHOD: In 517 hypertensives we analyzed left ventricular mass indexed for body surface area, and we assayed plasma levels of 8-isoprostaglandin F2alpha and high sensitivity C reactive protein. RESULTS: Multivariate analysis carried out considering left ventricular mass as dependent variable, and including 8-isoprostaglandin F2alpha, hig…

Hypoadiponectinemia: A Link between Visceral Obesity and Metabolic Syndrome

2012

Metabolic syndrome (MetS) represents a combination of cardiometabolic risk factors, including visceral obesity, glucose intolerance or type 2 diabetes, elevated triglycerides, reduced HDL cholesterol, and hypertension. MetS is rapidly increasing in prevalence worldwide as a consequence of the “epidemic” obesity, with a considerable impact on the global incidence of cardiovascular disease and type 2 diabetes. At present, there is a growing interest on the role of visceral fat accumulation in the occurrence of MetS. In this review, the effects of adipocytokines and other proinflammatory factors produced by fat accumulation on the occurrence of the MetS have been also emphasized. Accordingly, …

Has something changed in the smoking attitudes of parents in the household in the last 15 years? Epidemiological survey among the students of the cit…

2012

BACKGROUND: Exposure of children to passive tobacco smoking in the household setting has been demonstrated to cause respiratory diseases. Early atherosclerosis has also been demonstrated in young people previously exposed to passive tobacco smoking. Functional damage can initiate at the fetal age due to maternal smoking, with a tendency towards over-time progress. To date only scant data are available about indoor parental smoking attitudes and their changes after campaigns against smoke and risk factors in exposed youths. Questionnaires are useful tools in order to search for information on cigarette smoking and parental household lifestyle. In this study, we asked pupils of primary school…

Position paper on the management of patients with obstructive sleep apnea and hypertension: joint recommendations by the European Society of Hyperten…

2012

This article is aimed at addressing the current state of the art in epidemiology, pathophysiology, diagnostic procedures and treatment options for appropriate management of obstructive sleep apnea (OSA) in cardiovascular (particularly hypertensive) patients, as well as for the management of cardiovascular diseases (particularly arterial hypertension) in OSA patients. The present document is the result of the work done by a panel of experts participating in the European Union COST (COoperation in Scientific and Technological research) ACTION B26 on OSA, with the endorsement of the European Respiratory Society (ERS) and the European Society of Hypertension (ESH). These recommendations are par…

IS A 3D SPECKLE TRACKING ALGORITHM SYNONYMOUS WITH BETTER ESTIMATION OF LEFT VENTRICULAR FUNCTION?

Speckle tracking analysis: a new tool for left atrial function analysis in systemic hypertension: an overview

2014

Speckle tracking echocardiography (STE) is an imaging technique applied to the analysis of left atrial function. STE provides a non-Doppler, angle-independent and objective quantification of left atrial myocardial deformation. Data regarding feasibility, accuracy and clinical applications of left atrial strain are rapidly gathering. This review describes the fundamental concepts of left atrial STE, illustrates its pathophysiological background and discusses its emerging role in systemic arterial hypertension.

Low levels of testosterone levels increase the risk of major cardiovascular events in a follow-up to 5 years

2014

Materials and Methods. We evaluated a series of 802 patients with intermediate cardiovascular risk according to the Framingham Risk Score (FRS). The endothelial function through flow-mediated vasodilatation (FMD), the erectile function (EF), and the total serum testosterone levels were assessed. Patients were followed for up to 5 years and the prevalence and predictors of MACEs were evaluated. Results. The levels of serum testosterone are related with both endothelial function (FMD) (t=9,4080, 95% CI= 0,9318 to 1,4234, p<0,0001) and erectile function (FMD) (t=8,9584, 95% CI= 0,7642 to 1,1932, p<0,0001). Analysis of variance (ANOVA) of serum testosterone levels are related with the MACEs (F-…
