Chagas' Cardiomyopathy

چکیده
Background The fundamental determinant of the natural history of Chagas' disease is cardiac involvement. Methods and Results We studied 104 male patients with congestive heart failure due to Chagas' disease to estimate the survival distribution function and to evaluate age, functional class (FC), maximal oxygen consumption (Vo2max ), and ejection fraction (EF) as predictors of survival. Statistical evaluation was performed through univariate (Student's t test and X2 test) and multivariate analyses (Cox's regression model). Overall survival was 66% at 1 year, 56% at 3 years, and 48% at 5 years. Ages were not statistically different (P=.9811) between survivor (40.3±8.7) and nonsurvivor (40.3±9.4) groups. The ejection fraction(s) were statistically different (P=.0001) between survival (43.6±9.9) and nonsurvival

Comparison of outcome between Chagas cardiomyopathy and idiopathic dilated cardiomyopathy.
BACKGROUND Little is known about the outcome of patients with Chagas cardiomyopathy in comparison to that of patients with idiopathic dilated cardiomyopathy in the contemporary era. OBJECTIVE To compare the outcome of chagasic patients with chronic systolic heart failure secondary to Chagas cardiomyopathy with that observed in patients with IDC in the contemporary era.

متن کاملDistinct patterns of autoantibodies against G-protein-coupled receptors in Chagas' cardiomyopathy and megacolon. Their potential impact for early risk assessment in asymptomatic Chagas' patients.
OBJECTIVES Distinguishing the patterns of autoantibodies (AAB) against G-protein-coupled receptors in Chagas' cardiomyopathy and megacolon and the discovery of such a pattern in patients who are as yet asymptomatic could help to identify patients at high risk of developing the life-threatening complications of Chagas' disease. BACKGROUND Such AAB against receptors as beta 1 (beta1-AAB), beta ...
متن کاملChronic Chagas cardiomyopathy: a review of the main pathogenic mechanisms and the efficacy of aetiological treatment following the BENznidazole Evaluation for Interrupting Trypanosomiasis (BENEFIT) trial
Chagas cardiomyopathy is the most frequent and most severe manifestation of chronic Chagas disease, and is one of the leading causes of morbidity and death in Latin America. Although the pathogenesis of Chagas cardiomyopathy is incompletely understood, it may involve several mechanisms, including parasite-dependent myocardial damage, immune-mediated myocardial injury (induced by the parasite it...
متن کامل[Endothelial function and high-sensitivity C-reactive protein levels in patients with Chagas disease living in a nonendemic area].
INTRODUCTION AND OBJECTIVES The number of patients with Chagas disease in Spain has increased significantly. Chronic inflammation and endothelial dysfunction have been considered among the physiopathological mechanisms of Chagas heart disease. However, there have been conflicting data from clinical studies. Our purpose was to assess endothelial function and systemic levels of nitric oxide and h...
متن کاملPredictors of mortality in patients with dilated cardiomyopathy: relevance of chagas disease as an etiological factor.
INTRODUCTION AND OBJECTIVES Previous studies on the influence of Chagas disease on mortality in patients with heart failure were limited by the heterogeneity of the patient populations. Few data are available on the association between the underlying cause of dilated cardiomyopathy and long-term prognosis. The aims of this study were to identify risk factors for mortality in patients with dilat...
متن کاملComprehensive analysis of three TYK2 gene variants in the susceptibility to Chagas disease infection and cardiomyopathy
Tyrosine kinase 2 (TYK2) is a member of the Janus kinases family implicated in the signal transduction of type I interferons and several interleukins. It has been described that genetic mutations within TYK2 lead to multiple deleterious effects in the immune response. In this work, we have analyzed three functional independent variants from the frequency spectrum on the TYK2 gene (common and lo...
