    ABSTRACT: The purpose of this study was to evaluate the prognostic significance of anemia on outcome of patients with chronic systolic heart failure secondary to Chagas' cardiomyopathy, as no previous study has previously addressed this question. One-hundred-eight-six patients followed for chronic systolic heart failure secondary to Chagas' cardiomyopathy at our Institution from January 2000 to December 2008 were studied. Forty-nine (26%) patients were found to have anemia; 37 (20%) were men and 12 (6%) were women. Mean hemoglobin level was 14.1±1.2g/L in patients with no anemia and 11.5±1.2g/L in patients with anemia. On a Cox proportional hazards multivariate analysis, anemia was a predictor of all-cause mortality neither in the univariate nor in the multivariate analysis. Mean serum sodium (Hazard ratio=0.92; Beta-coefficient=-0.09; 95% confidence interval 0.89-0.96; p value<0.005), and Beta-Blocker therapy (Hazard ratio=0.40; 95% confidence interval 0.26-0.61; p value<0.005) were retained as independent predictors of mortality for patients with Chagas' cardiomyopathy with chronic heart failure. Probability of survival for patients with anemia, however, was significantly lower in patients with anemia in comparison to patients with no anemia, mainly in patients with advanced heart failure. Anemia is not an independent predictor of all-cause mortality in patients with Chagas' cardiomyopathy with chronic systolic heart failure. Probability of survival is poorer in patients with anemia than in those without.

    ABSTRACT: Primary cardiac lymphoma (PCL) is a very rare disorder. Histologically, the majority of cases of PCL are diffuse B-cell lymphoma. PCL occurs more frequently in immunocompromised patients. Symptoms may vary according to the heart site involved. The most frequent cardiac clinical manifestations associated with PCL are pericardial effusion, heart failure, and atrioventricular block (AV-block). Diagnosis of PCL can be suggested by transesophageal echocardiography, computed tomography, and magnetic resonance imaging. However, cytologic examination of cardiac tumor or pericardial effusion is paramount for a definite diagnosis of this condition. Prognosis of PCL is poor with a median survival of 7months after initial diagnosis. Newer modalities including immunotherapy with rituximab or auto stem cell transplantation are promising in the treatment of this lethal condition.
