Characterization of Cardiopulmonary Exercise Testing Variables in Patients with Endomyocardial Fibrosis after Endocardial Resection

Arq. bras. cardiol; 109 (6), 2017
Abstract Background: Endomyocardial fibrosis (EMF) is a rare disease, characterized by diastolic dysfunction which leads to reduced peak oxygen consumption (VO2). Cardiopulmonary exercise testing (CPET) has been proved to be a fundamental tool to identify central and peripheral alterations. However, mos...

Predictors of Total Mortality and Echocardiographic Response for Cardiac Resynchronization Therapy: A Cohort Study

Arq. bras. cardiol; 109 (6), 2017
Abstract Background: Clinical studies demonstrate that up to 40% of patients do not respond to cardiac resynchronization therapy (CRT), thus, appropriate patient selection is critical to the success of CRT in heart failure. Objective: Evaluation of mortality predictors and response to CRT in the Brazil...

Incremental Prognostic Value of Conventional Echocardiography in Patients with Acutely Decompensated Heart Failure

Arq. bras. cardiol; 109 (6), 2017
Abstract Background: Acutely decompensated heart failure (ADHF) presents high morbidity and mortality in spite of therapeutic advance. Identifying factors of worst prognosis is important to improve assistance during the hospital phase and follow-up after discharge. The use of echocardiography for diagno...

Endocarditis infecciosa asociada a catéter de hemodiálisis: hallazgos clínicos y ecocardiográficos

Rev. chil. cardiol; 36 (3), 2017
Resumen: Hallazgos clínicos y ecocardiográficos en pacientes con endocarditis infecciosa (E.I.) asociada a catéter de hemodiálisis (CHD) fueron comparados con sujetos controles con E.I. "habitual". Pacientes y métodos: Del total de registros ecocardiográficos de una Clínica privada de Antofagasta...

Hipertrofia ventricular izquierda con patrón de strain característico

Rev. chil. cardiol; 36 (3), 2017
Abstracts: A 68 year-old male, with no past medical history, presented progressive shortness of breath on exertion and leg edema during the previous year. Trans-thoracic echocardiography depicted; severe left ventricular hypertrophy with mild systolic dysfunction (LVEF 50% biplane Simpson's method), seve...

Global longitudinal strain as a biomarker in diabetic cardiomyopathy. A comparative study with Gal-3 in patients with preserved ejection fraction

Arch. cardiol. Méx; 87 (4), 2017
Abstract: Objectives: To establish a relationship between global longitudinal strain (GLS) and Galectin-3 in pre-clinical heart failure in diabetic patients. Galectin-3 is a biomarker in heart failure with depressed ejection fraction (HFdEF). The hypothesis is presented that Galectin-3 is related to GL...

Endostatin a Potential Biomarker for Heart Failure with Preserved Ejection Fraction

Arq. bras. cardiol; 109 (5), 2017
Abstract Background: Endostatin is a circulating endogenous angiogenesis inhibitor preventing neovascularization. Previous studies demonstrated the prognostic value of Endostatin among patients with heart failure with reduced ejection fraction (HFrEF). However, the role of Endostatin among patients with...

Importance of Clinical and Laboratory Findings in the Diagnosis and Surgical Prognosis of Patients with Constrictive Pericarditis

Arq. bras. cardiol; 109 (5), 2017
Abstract Background: International studies have reported the value of the clinical profile and laboratory findings in the diagnosis of constrictive pericarditis. However, Brazilian population data are scarce. Objective: To assess the clinical characteristics, sensitivity of imaging tests and factors re...

Radioterapia e cardiotoxicidade

Os avanços da radioterapia aumentaram a taxa de sobrevida dos pacientes em tratamento oncológico em até 90% em alguns casos. A prevalência acumulada de doença cardíaca relacionada com a radioterapia é estimada em 10% a 30% de 5 a 10 anos após o tratamento e é dose-dependente. A dose acumulada e ...
