Dear Editor, We would like to share ideas on the publication “Prognostic Value of Troponin-T and B-Type Natriuretic Peptide in Patients Hospitalized for COVID-19 [1].” Almeida Jr. et al. reported using Memory box as a tool to support grief and concluded that “In the first 24h of admission, TnT, but not BNP, was an independent marker of mortality or need for invasive mechanical ventilation.” In COVID-19, cardiac complication is possible and is common in severe infection. Myocardial involvement is a […]

Abstract Background The histopathological characteristics of Chagas disease (ChD) are: presence of myocarditis, destruction of heart fibers, and myocardial fibrosis. Galectin-3 (Gal-3) is a biomarker involved in the mechanism of fibrosis and inflammation that may be useful for risk stratification of individuals with ChD. Objectives We sought to evaluate whether high Gal-3 levels are associated with severe forms of Chagas cardiomyopathy (CC) and whether they are predictive of mortality. Methods We studied anti-T. cruzi positive blood donors (BD): Non-CC-BD (187 […]

Abstract In the last years, several diagnostic and prognostic biomarkers have been studied in cardiovascular disease. Growth differentiation factor-15 (GDF-15), a cytokine belonging to the transforming growth factor- (TGF-) family, is highly up-regulated in stress and inflammatory conditions and has been correlated to myocardial injury and pressure cardiac overload in animal models. This new biomarker has been positively correlated with increased risk of cardiovascular events in population studies and shown an independent predictor of mortality in patients with coronary artery […]

Abstract Background Cardiovascular diseases (CVD) are one of the leading causes of mortality and morbidity worldwide. Biological aging has been associated with the occurrence of adverse cardiovascular outcomes; however, the underlying mechanism of this process remains unknown. Objectives This study sought to evaluate if peripheral blood mononuclear cell (PBMC) senescence and endothelial biomarkers could influence cardiovascular (CV) risk and be suitable markers for the early detection of cardiovascular diseases in adults. Methods In this cross-sectional study patients free of CVD […]

Introduction The Heart Failure Summit Brazil 2020 addressed new perspectives for assessment, diagnosis, risk stratification, and management of heart failure (HF), which may soon be available for widespread use in the clinic. These strategies involve the use of novel biomarkers, genetic assessment, potential new therapeutic targets, and personalized medicine. […]

Abstract Background: COVID-19 causes severe pulmonary involvement, but the cardiovascular system can also be affected by myocarditis, heart failure and shock. The increase in cardiac biomarkers has been associated with a worse prognosis. Objectives: To evaluate the prognostic value of Troponin-T (TNT) and natriuretic peptide (BNP) in patients hospitalized for Covid-19. Methods: This was a convenience sample of patients hospitalized for COVID-19. Data were collected from medical records to assess the association of TnT and BNP measured in the first […]

Francisco, 64 years old, comes to your office for a preventive health evaluation. He has a history of well-controlled hypertension and is otherwise well. His past medical history is unremarkable. No family history of cardiovascular disease or smoking and LDL-cholesterol (LDL-C) of 90 mg/dL. After discussing with the patient, you are unsure if this patient’s risk benefit profile would favor the use of statins. Instead of trusting your personal feelings, you decide to use the Framingham risk score (FRS) to […]
