Inappropriate activity of local renin-angiotensin-aldosterone system during high salt intake: impact on the cardio-renal axis

J. bras. nefrol; 40 (2), 2018
ABSTRACT Although there is a general agreement on the recommendation for reduced salt intake as a public health issue, the mechanism by which high salt intake triggers pathological effects on the cardio-renal axis is not completely understood. Emerging evidence indicates that the renin-angiotensin-aldost...

Etiología de la insuficiencia cardíaca crónica

Rev. med. Risaralda; 23 (2), 2017
La insuficiencia cardiaca es el resultado fisiopatológico de múltiples enfermedades. Además de la patologia isquémica, valvular, de la conducción o hipertensiva existen otras etiologías poco sospechadas. En la mayoría de ocasiones se realizan diagnósticos estructurales basados en la imagenologia ...

O que o cardiologista precisa saber sobre achados torácicos na tomografia

A angiotomografia das artérias coronárias é um método diagnóstico não invasivo que pode ser utilizado para avaliação da doença arterial coronariana em pacientes selecionados e pode fornecer informações quanto às demais estruturas incluídas no campo de visão tomográfico. Por vezes são iden...

Cardiac Regeneration using Growth Factors: Advances and Challenges

Arq. bras. cardiol; 107 (3), 2016
Abstract Myocardial infarction is the most significant manifestation of ischemic heart disease and is associated with high morbidity and mortality. Novel strategies targeting at regenerating the injured myocardium have been investigated, including gene therapy, cell therapy, and the use of growth factors...

Assessment of the left ventricular function in normotensive prediabetics: a tissue Doppler echocardiography study

ABSTRACT Objective Several studies have shown that left ventricular (LV) dysfunction is increased in individuals with diabetes. However, there are scarce data about LV function in prediabetics. This study assessed the early changes in LV diastolic and systolic myocardial function in normotensive predia...

Electrocardiographic exam in female spotted pacas (Cuniculus paca)

Pesqui. vet. bras; 36 (6), 2016
Considering the limited physiological information available on neotropical rodents and the importance of this information for pathophysiological and conservation studies of these species, the aim of this study was to evaluate the cardiac electric physiology of healthy captivity spotted pacas (Cuniculus p...

Interval and continuous exercise enhances aerobic capacity and hemodynamic function in CHF rats

OBJECTIVE: The aim of the present study was to compare the effects of continuous versus interval aerobic exercise training on hemodynamic parameters, cardiac remodeling, and maximal exercise capacity (MEC) in chronic heart failure (CHF) rats.METHOD: Twenty-four male Wistar rats were subjected to myocardi...
