Selected clinically stable patients with heart failure (HF) who require prolonged intravenous inotropic therapy may benefit from its continuity out of the intensive care unit (ICU). We aimed to report on the initial experience and safety of a structured protocol for inotropic therapy in non-intensive care units in 28 consecutive patients hospitalized with HF that were discharged from ICU. The utilization of low to moderate inotropic doses oriented by a safety-focused process of care may reconfigure their role as a […]

Abstract Background: The low or non-adherence to reduction of sodium intake has been identified as one of the main precipitating factors of heart failure (HF). The Dietary Sodium Restriction Questionnaire (DSRQ) identifies factors that can interfere with adherence to this recommendation. However, there is still no cut-point to define adherence for this questionnaire. Objectives: To identify the cut-point for satisfactory adherence to the Brazilian version of the DSRQ, (the Questionário de Restrição de Sódio na Dieta, QRSD). Methods: Multicenter study. […]

Abstract Background: Pioglitazone has been widely used as an insulin-sensitizing agent for improving glycemic control in patients with type 2 diabetes mellitus. However, cardiovascular risk and protective effects of pioglitazone remain controversial. Objectives: In this study, we investigated whether pioglitazone affects cardiomyocyte apoptosis and hypertrophy by regulating the VEGFR-2 signaling pathway. Methods: Cardiomyocytes were enzymatically isolated from 1- to 3-day-old Sprague-Dawley rat ventricles. Effects of pioglitazone and the VEGFR-2-selective inhibitor apatinib on cardiomyocyte apoptotic rate was determined using flow cytometry, […]

Dear Editor, We read the article “Non-Sustained Ventricular Tachycardia (NSVT) Episodes Predict Future Hospitalization in ICD Recipients with Heart Failure” written by Uçar et al. with great interest. NSVT identified on routine ICD interrogation should be considered an important clinical event as the authors state in this article. However, we would like to bring attention to some issues related to the article. […]

Clinical aspects The patient here reported is a male elderly with ischemic cardiomyopathy, and significant weight loss in the previous 4 months, in addition to worsening of his general state of health and clinical instability in the 24 hours prior to admission. Some diagnostic possibilities could explain his significant weight loss. Cardiac cachexia is a frequent complication in the advanced stages of congestive heart failure (CHF) and associates with shorter survival. The physiopathology of that disorder has been first described […]

Abstract Heart transplantation (HTx) is considered an efficient and gold-standard procedure for patients with end-stage heart failure. After surgery, patients have lower aerobic power (VO2max) and compensatory hemodynamic responses. The aim of the present study was to assess through a systematic review with meta-analysis whether high-intensity interval training (HIIT) can provide benefits for those parameters. This is a systematic review with meta-analysis, which searched the databases and data portals PubMed, Web of Science, Scopus, Science Direct and Wiley until December […]

A 74-year-old woman with a history of membranous glomerulonephritis and a recent diagnosis of mediastinal adenopathy was admitted to the emergency department with acute heart failure. She complained of progressive dyspnea and weakness in the last week. Physical examination revealed hypotension, tachypnea, jugular vein distention, and desaturation. The most relevant laboratory findings were: anemia, lymphocytopenia, lactic acidosis, and increased lactate dehydrogenase. An electrocardiogram showed rapid atrial fibrillation and low-voltage QRS complexes. An echocardiogram revealed severe pericardial effusion and diffuse heterogeneous […]
