Long-Term Intermittent Work at High Altitude: Right Heart Functional and Morphological Status and Associated Cardiometabolic Factors
(Frontiers Media, 2018)
Background: Living at high altitude or with chronic hypoxia implies functional and morphological changes in the right ventricle and pulmonary vasculature with a 10% prevalence of high-altitude pulmonary hypertension (HAPH). ...
Associação entre variáveis funcionais e insuficiência cardíaca após o infarto do miocárdio em ratos association between
Background: Heart failure prediction after acute myocardial infarction may have important clinical implications. Objective: To analyze the functional echocardiographic variables associated with heart failure in an infarction ...
Massive Degeneration and Atrophy of the Native Heart After Heterotopic Transplantation: A Case Report
(ELSEVIER SCIENCE INC, 2009)
Extreme myocardial degeneration leading to advanced stages of cardiomyopathy with extensive atrophy is rarely observed before patients die. However, heterotopic transplantation is a special situation wherein this phenomenon ...
Narrowed lumen of the right coronary artery in chronic chagasic patients is associated with ischemic lesions of segmental thinnings of ventricles
(INST INVESTIGACION CLINICA, 2010)
Thinning of myocardial segments, mainly at the apex and basal posterior region of left ventricle, are frequent lesions in chronic chagasic cardiopathy (CCC), but still without a well determined etiology. Previously we found ...
Predictors of Right Ventricle Dysfunction After Anterior Myocardial Infarction
(Elsevier B.V., 2012-07-01)
Background: Regardless significant therapeutic advances, mortality and morbidity after myocardial infarction (MI) are still high. For a long time, the importance of right ventricle (RV) function has been neglected. Recently, ...
Does quantitative left ventricular regional wall motion change after fibrous tissue resection in endomyocardial fibrosis?
(Faculdade de Medicina / USP, 2009)
OBJECTIVES: We compared left ventricular regional wall motion, the global left ventricular ejection fraction, and the New York Heart Association functional class pre- and postoperatively. INTRODUCTION: Endomyocardial ...
Atrophic Cardiac Remodeling Induced by Taurine Deficiency in Wistar Rats
(Public Library Science, 2012-07-23)
Introduction: Micronutrient deficiency is observed in heart failure patients. Taurine, for example, represents 50% of total free amino acids in the heart, and in vivo studies have linked taurine deficiency with ...
Quantificação de tecido conjuntivo do músculo cardíaco em equinos de tração através de técnicas histoquímicas e morfométricas
(Universidade Federal de Santa Maria, 2011)
Os cardiomiócitos são sustentados e inseridos em um esqueleto de tecido conjuntivo, este possui distribuição desigual de acordo com as propriedades das distintas regiões em que se encontra. O propósito deste estudo foi ...
Diaphragm Degeneration And Cardiac Structure In Mdx Mouse: Potential Clinical Implications For Duchenne Muscular Dystrophy
