Effect of gestational protein restriction on left ventricle hypertrophy and heart angiotensin II signaling pathway in adult offspring rats
Maternal protein restriction may be a risk factor for cardiovascular disorders in adulthood. The RAS (renin-angiotensin-system) plays a pivotal role in cardiac remodeling. Components of the RAS, including angiotensin II ...
Developed pressure data may provide misinformation when used alone to evaluate systolic function in isovolumetric left ventricle preparations
(Associação Brasileira de Divulgação Científica, 1999-06-01)
We report data showing that developed pressure (DPmax) may lead to opposite conclusion with respect to maximal developed circumferential wall stress (smax) when used to assess contractile function in left ventricle isovolumic ...
Could albumin level explain the higher mortality in hemodialysis patients with pulmonary hypertension?
Background: The pathogenesis of pulmonary hypertension (PH) in hemodialysis is still unclear. The aim of thisstudy was to identify the risk factors associated with the presence of PH in chronic hemodialysis patients and ...
Thyrotropin-Releasing Hormone Overexpression induces structural changes of the Left Ventricle in the normal Rat heart
(American Physiological Society, 2014-10)
Thyrotropin-releasing hormone (TRH) hyperactivity has been observed in the left ventricle of spontaneously hypertensive rats. Its long-term inhibition suppresses the development of hypertrophy, specifically preventing ...
Rupture of the right ventricular free wall after myocardial infarction
(SOC BRASIL CIRURGIA CARDIOVASCSAO PAULO SP, 2012)
Patient, 75 years-old, with free wall rupture of the right ventricle, corrected with prolene 3.0 points anchored in bovine pericardium patch, promoting the closure of the rupture. The patient was discharged on the 59th day ...
Echocardiographic predictors of ventricular remodeling after acute myocardial infarction in rats
Background: The prediction of the ventricular remodeling process after acute myocardial infarction (AMI) may have important clinical implications. Objetive: To analyze echocardiographic variables predictors of remodeling ...
A CASE OF BILATERAL SUPERIOR VENA-CAVA WITH VARIATIONS IN THE AZYGOS SYSTEM AND IN THE HEART
(Gustav Fischer Verlag JenaJenaAlemanha, 1994)
Force patterns of hypoxic myocardium applied to oxygenated muscle preparations: Comparison with effects of regional ischemia on the contraction of non-ischemic myocardium
Objective: To examine the basis for local wall motion abnormalities commonly seen in patients with ischemic heart disease, computer-controlled isolated muscle studies were carried out. Methods: Force patterns of physiologically ...
β-Carotene supplementation results in adverse ventricular remodeling after acute myocardial infarction
Objective: We studied the effects of β-carotene (BC) on ventricular remodeling after myocardial infarction. Methods: Myocardial infarction was induced in Wistar rats that were then treated with a BC diet (500 mg/kg of diet ...
