Abstract Background: Different immune mechanisms of myocardial damage involved in the pathophysiology of Chagas disease coexist with high titers of autoantibodies induced by T. cruzi . There are few studies in the literature about the adaptive role of anti-β1 and anti-M2 antibodies in chronic Chaga...
Introdução: A doença de Chagas é uma infecção causada pelo protozoário Trypanosoma cruzi. É considerada um importante problema de saúde do mundo, tendo como manifestações a dilatação cardíaca, arritmias e morte. A insuficiência cardíaca é uma síndrome complexa e de elevada morbimortalid...
Fundamento: A identificação precoce do dano miocárdico parece ser importante na abordagem do paciente com doença de Chagas. A ecocardiografia com strain obtida por speckle tracking e a avaliação da fibrose miocárdica por meio da ressonância magnética cardíaca podem ser métodos diagnósticos pr...
Abstract Several different imaging methods can be used to evaluate patients with Chagas heart disease (CHD) for diagnostic and prognostic purposes, including plain chest radiography; echocardiography; myocardial perfusion scintigraphy, for detection of ischemia and fibrosis; radionuclide gated-angiograph...
Abstract Patients with Chagas cardiomyopathy (ChC) usually progress with fatigue and dyspnea. Exercise tests are valuable for the functional evaluation of these patients. However, information about the applicability of the exercise tests is scattered, and no studies have systematically reviewed the resul...
Abstract Changes in iron metabolism in heart failure (HF) have been described as an important prognostic marker. To check if the markers of iron kinetics are related to the morbidity and etiology of chagasic cardiomyopathy. Patients with Chronic Chagasic Cardiomyopathy (CCC, n = 40), with indeterminate f...
Abstract INTRODUCTION: We investigated the occurrence of coronary sinus abnormalities in the indeterminate form of Chagas disease (CD). METHODS: Differences between the maximum and minimum diameters of the coronary sinus (∆%) on echocardiography were evaluated in individuals with the indetermin...
Abstract Background: Heart failure (HF) is a severe public health problem because of its high morbidity and mortality and elevated costs, thus requiring better understanding of its course. In its complex and multifactorial pathogenesis, sympathetic hyperactivity plays a relevant role. Considering that s...
