Abstract Background Hypertension is an increasingly common problem in adolescents; amongst the associated factors, physical inactivity and obesity are increasing the risk of developing cardiovascular diseases. Objective To verify whether there is an association between higher blood pressure levels amongst adolescents with the relationship between different levels of body mass index (BMI) and cardiorespiratory fitness (CRF). Method Cross-sectional study consisting of 860 adolescents. Higher blood pressure (BP) was considered as borderline and hypertension as the classification. BMI was categorized as […]

Abstract Background Lipoprotein (a) is a cardiovascular risk factor in adult. Studies have shown the presence of this emergent risk factor in school children, which may contribute to the development of atherosclerosis in adulthood. Objective To evaluate the association between lipoprotein (a) and cardiovascular risk factors in school children. Methods Lipoprotein (a) levels were measured in 320 school children (6-14 years) selected from a population survey carried out in Ouro Preto (southeast of Brazil). Demographic (sex and age), biochemical (total […]

Background: Although associated with traditional cardiovascular risk factors, it is unclear whether obesity alone is associated with coronary artery disease (CAD). Objective: To investigate the role of obesity as a risk factor for CAD, defined by coronary computed tomography angiography (CCTA). Methods: This study retrospectively included 1,814 patients referred for CCTA in a hospital in São Paulo, from August 2010 to July 2012. CAD was identified by coronary calcium score and presence of coronary stenosis > 50%. Images were analyzed […]

Resumo Fundamentos: O conhecimento do ângulo de fase e seu uso como determinante prognóstico em pacientes com insuficiência cardíaca ainda é escasso. Objetivo: Avaliar a relação entre indicadores antropométricos, função cardíaca e integridade celular em pacientes com insuficiência cardíaca com fração de ejeção reduzida. Métodos: Trata-se de um estudo transversal que avaliou pacientes com insuficiência cardíaca com fração de ejeção reduzida por meio da antropometria e da bioimpedância elétrica. Foram empregados os testes do Qui-quadrado e teste t de student […]
