14. Outbreaks of nutritional cardiomyopathy in pigs in Brazil
RESUMO: Cardiomiopatia dilatada (CMD) é uma condição que afeta o miocárdio, raramente relatada em porcos. A DCM é caracterizada por dilatação ventricular, que resulta em disfunção sistólica e disfunção diastólica secundária e pode levar a arritmias e insuficiência cardíaca congestiva fatal. Este estudo descreve os achados clínicos, patológi

15. Clinical and anatomopathological aspects of patients with hantavirus cardiopulmonary syndrome in Uberaba, Minas Gerais, Brazil
ABSTRACT The hantavirus cardiopulmonary syndrome is considered an emerging disease in the Americas. Since 1993, thousands of cases have been reported from different countries, but mainly from Brazil. This study aims to describe some epidemiological, clinical and anatomopathological aspects of patients with hantavirus who presented poor outcome and were autop

16. DACT1 Involvement in the Cytoskeletal Arrangement of Cardiomyocytes in Atrial Fibrillation by Regulating Cx43
Abstract Objective: To determine the role of the dishevelled binding antagonist of beta catenin 1 (DACT1) in the cytoskeletal arrangement of cardiomyocytes in atrial fibrillation (AF). Methods: The DACT1 expression and its associations with the degree of fibrosis and β-catenin in valvular disease patients were analyzed by immunohistochemistry and Masson�

17. The Effect of Continuous Ventilation on Thiol-Disulphide Homeostasis and Albumin-Adjusted Ischemia-Modified Albumin During Cardiopulmonary Bypass
Abstract Objective: To investigate the effect of continuous lung ventilation with low tidal volume on oxidation parameters, such as thiol/disulphide homeostasis and albumin-adjusted ischemia-modified albumin (AAIMA), during cardiopulmonary bypass (CBP) in coronary artery bypass grafting (CABG). Methods: Seventy-four patients who underwent elective CABG wit

18. Acute petrified myocardium associated with meningococcal sepsis in childhood-onset systemic lupus erythematous: a fatal case
ABSTRACT Acute petrified myocardium associated with septic shock, diagnosed by autopsy has rarely been described. A 15-year-old adolescent male was diagnosed with childhood-onset systemic lupus erythematosus. One year later, he was hospitalized with fever, myalgia, headache, arthritis, vomiting, dyspnea and was diagnosed with sepsis secondary to bronchopneum

19. The effect of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) on mice myocardial morphology
RESUMO: Estudos têm demonstrado a desnervação simpática cardíaca no modelo da administração do MPTP em camundongo. A toxicidade do MPTP causa lesão ao nervo simpático e depleção da norepinefrina. As avaliações dos danos na inervação do coração são baseadas em métodos de imagem, eletrofisiológico e bioquímico. Contudo, estes estudos carec

20. Cardiac Manifestation of Fabry Disease: From Hypertrophic Cardiomyopathy to Early Diagnosis and Treatment in Patients Without Left Ventricular Hypertrophy
Abstract Although Fabry disease was identified a century ago, it is still a challenging condition to diagnose and treat. Registries data suggest that at least 10% of patients may first present with a cardiac event and that cardiac disease is 1 of the 3 major causes of morbidity and mortality in affected males and females. Cardiac involvement in Fabry disease

21. Cardiac Magnetic Resonance and amyloidosis: Review
Abstract Amyloidosis is a disease caused by extracellular deposition of insoluble protein fibrils, that results in changes in tissue architecture and consequently modification of the organ structure. Cardiac involvement is common in amyloidosis. Two major types of systemic amyloidosis affect the myocardium - immunoglobulin light chain and transthyretin amylo

22. Isolated Non-Compacted Myocardium: Should We Consider the Presence of Extrasystoles as the Initial Manifestation?
Abstract Ventricular non-compaction occurs due to failure in myocardial morphogenesis during the fetal period. Patients can have heart failure, as well as systemic complications due to thromboembolism and cardiac arrhythmias. Early diagnosis is essential. We present the case of an asymptomatic 49-year-old woman who initially manifested ventricular extrasysto

23. Myocardial Viability: From PARR-2 to IMAGE HF - Current Evidence and Future Directions
Abstract Ischemic heart failure is a growing disease with high morbidity and mortality. Several studies suggest the benefit of viability imaging to assist revascularization decision, but there is controversy. Multiple imaging modalities can be used to accurately define hibernating myocardium; however, the best approach remains uncertain. This review will hig

24. Current Practice of State-of-the-Art Coronary Revascularization in Patients with Heart Failure
Abstract The best treatment for patients with ischemic heart failure (HF) is still on debate. There is growing evidence that coronary artery bypass graft (CABG) benefits these patients. The current recommendations for revascularization in this context are that CABG is reasonable when it comes to decreasing morbidity and mortality rates for patients with seve
