Utilidad del índice de choque para predecir la mortalidad en pacientes pediátricos con sepsis grave o choque séptico

Resumen Introducción: La sepsis en pediatría es la principal causa de muerte hospitalaria. Se han intentado crear herramientas que faciliten su identificación, como el índice de choque (IC), definido como el cociente entre frecuencia cardíaca y tensión arterial sistólica. El objetivo de este tra...

Is the early or delayed remote ischemic preconditioning the more effective from a microcirculatory and histological point of view in a rat model of partial liver ischemia-reperfusion?

Acta cir. bras; 33 (7), 2018
Abstract Purpose: To compare early- and late-effect remote ischemic preconditioning (RIPC) by analysing the microcirculatory, hemodynamic and histological changes in partial liver ischemia-reperfusion of rats. Methods: 60-minute partial liver ischemia followed by 120-minute reperfusion was performed ...

Ejercicio físico en pacientes con diabetes e hipertensión: prevalencia de respondedores y no respondedores para mejorar factores de riesgo cardiometabólicos

Rev. méd. Chile; 146 (6), 2018
Background: There is a wide interindividual variability in the response to a period of exercise training. The science have reported that a minimum of participants could be non-responders for improving different health-related outcomes after training. Aim: To compare the effects of a 6-weeks exercise pro...

Metabolic Syndrome-Related Features in Controlled and Resistant Hypertensive Subjects

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: Metabolic syndrome (MetS) is widespread among hypertensive patients. Clinical features and potential biomarkers of MetS in the presence of hypertension and resistant hypertension (RHTN) represent a great area of interest for investigation. Objective: The purpose of this study was t...

Endothelial Dysfunction and Inflammation Precedes Elevations in Blood Pressure Induced by a High-Fat Diet

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: Obesity leads to a chronic inflammatory state, endothelial dysfunction and hypertension. Objective: To establish the time-course of events regarding inflammatory markers, endothelial dysfunction, systolic blood pressure (SBP) in obesity in only one experimental model. Methods: We ...

Behavior of Blood Pressure Variables in Children and Adolescents with Duchenne Muscular Dystrophy

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: Duchenne muscular dystrophy is an X-chromosome-linked genetic disorder (locus Xp21). Involvement of the cardiovascular system is characterized by fibrous degeneration/replacement of myocytes with consequent ventricular hypertrophy and arterial hypertension. Objective: To assess, by...

Anthropometric changes and their effects on cardiometabolic risk factors in rural populations in Brazil

Abstract This article aims to evaluate associations between anthropometric changes in five years with lipid and blood pressure levels in Brazilian rural population. This longitudinal study evaluated 387 individuals aged 18 to 75 residents of two rural communities. Demographic, lifestyle, anthropometric, ...

Influence of Aerobic Training on The Mechanics of Ventricular Contraction After Acute Myocardial Infarction: A Pilot Study

Arq. bras. cardiol; 110 (4), 2018
Abstract The study of myocardial contractility, based on the new anatomical concepts that govern cardiac mechanics, represents a promising strategy of analysis of myocardial adaptations related to physical training in the context of post-infarction. We investigated the influence of aerobic training on ph...

Heart Rate and its Variability Assessed by Spectral Analysis in Elderly Subjects with Orthostatic Hypotension: A Case-Control Study

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: The prevalence of orthostatic hypotension (OH) increases with age and is associated with changes in autonomic regulation of blood pressure (BP) and heart rate (HR). Objective: to assess HR and HR variability (HRV) in elderly subjects with OH and determine OH predictors. Methods: a...
