The challenge of the century: overweight Published studies have shown that, worldwide, over the past 50 years, the population has increased in weight. A 2014 publication reported that between 1980 and 2013 individuals had an increase in body mass index above 25 kg/m2, which classifies them as overweight, from 28.8% to 36.9% among men and 29.8% to 38.0% among women. Worse than that, children and adolescents also had weight gain both in developed countries where, in 2013, 23.8% of boys […]

Background: Left ventricular global longitudinal strain value (GLS) can predict functional capacity in patients with preserved left ventricular ejection fraction (LVEF) heart failure (HF) and to assess prognosis in reduced LVEF HF. Objetive: Correlate GLS with parameters of Cardiopulmonary Exercise Test (CPET) and to assess if they could predict systolic HF patients that are more appropriated to be referred to heart transplantation according to CPET criteria. Methods: Systolic HF patients with LVEF < 45%, NYHA functional class II and III, […]

Background: Elevated plasma levels of Lipoprotein(a) [Lp(a)] are recognized as a significant risk factor for atherosclerotic vascular disease. However, there are limited data regarding association between Lp(a) and recurrent heart failure (HF) in patients with chronic HF caused by coronary heart disease (CHD). Objective: Elevated levels of Lp(a) might have a prognostic impact on recurrent HF in patients with chronic HF caused by CHD. Methods: A total of 309 patients with chronic HF caused by CHD were consecutively enrolled in […]

Background: Myocardial performance index (MPI), demonstrates both systolic and diastolic functions of the left ventricle. Presystolic wave (PSW) is frequently detected on Doppler examination of the left ventricular outflow tract and possible mechanism of PSW is impaired LV compliance and left ventricular stiffness. Objective: To investigate the relationship between PSW and MPI in type 2 diabetic patients. Method: A total of 129 type 2 diabetic patients were included in this study. Patients were divided into two groups according to the […]

Background: Studies have persuasively demonstrated that citrulline has a key role in the arginine-nitric oxide system, increasing nitric oxide bioavailability, an important mediator of peripheral vasodilation. Objective: To analyze the inter-individual post-exercise hypotension responsiveness following acute citrulline supplementation in hypertensives. Methods: Forty hypertensives were randomly assigned to one of the four experimental groups (control-placebo, control-citrulline, exercise-placebo, and exercise-citrulline). They ingested placebo or citrulline malate [CM] (6 grams). During the exercise session, individuals performed 40 minutes of walking/running on a treadmill […]

Background: Thoracic bioreactance (TB), a noninvasive method for the measurement of cardiac output (CO), shows good test-retest reliability in healthy adults examined under research and resting conditions. Objective: In this study, we evaluate the test-retest reliability of CO and cardiac power (CPO) output assessment during exercise assessed by TB in healthy adults under routine clinical conditions. Methods: 25 test persons performed a symptom-limited graded cycling test in an outpatient office on two different days separated by one week. Cardiorespiratory (power […]

Background: Psoriasis correlates with metabolic disorders, early atheromatosis and increased cardiovascular risk. Objectives: To assess markers of cardiovascular disease in psoriatic patients. Methods: Cross-sectional, observational study involving 11 psoriatic participants and 33 controls. Anthropometric, biochemical, hemodynamic and imaging parameters were evaluated. Arterial stiffness was assessed by oscillometric measurement of the brachial artery. Intima-media thickness (IMT) and left ventricular diastolic function were assessed by Doppler echography and echocardiography. Between-group comparisons of numerical variables were performed by the Student’s t-test or Wilcoxon […]

Background: Atrial fibrillation (AF) is the most common arrhythmia worldwide, with significantly associated hospitalizations. Considering its growing incidence, the AF related economic burden to healthcare systems is increasing. Healthcare expenditures might be substantially reduced after AF radiofrequency ablation (AFRA). Objective: To compare resource utilization and costs before and after AFRA in a cohort of patients from the Brazilian private healthcare system. Methods: We conducted a retrospective cohort study, based on patients’ billing information from an administrative database. Eighty-three adult patients […]

Background: Having appropriate dietary habits is part of the recommendations after ST-Elevation Myocardial Infarction (STEMI), however, the quality of intra-hospital nutritional counselling in the different health services has been minimally explored. Objective: To evaluate the quality of intra-hospital nutritional counselling among patients with STEMI in the public and private health systems in Sergipe. Methods: A cross-sectional, with data from the Via Crucis for the Treatment of Myocardial Infarction (VICTIM) Register, conducted from April to November of 2017, with individuals aged […]

Abstract Dilated cardiomyopathy (DCM) is a clinical syndrome characterized by left ventricular dilatation and contractile dysfunction. It is the most common cause of heart failure in young adults. The advent of next-generation sequencing has contributed to the discovery of a large amount of genomic data related to DCM. Mutations involving genes that encode cytoskeletal proteins, the sarcomere, and ion channels account for approximately 40% of cases previously classified as idiopathic DCM. In this scenario, geneticists and cardiovascular genetics specialists have […]

Clinical aspects Chagas’ disease was first described by Brazilian physician and scientist Carlos Chagas in 1909. This multifaceted disease is caused by the protozoan Trypanosoma cruzi, which can be transmitted in different ways. Vector transmission through hematophagous insects is the most classic one, although it has declined in importance in recent years with measures to control the vector population. Transfusion transmission, as well as vector transmission, have shown a drastic reduction in the last decades, and no cases have been […]

Introduction Exertional rhabdomyolysis (ER) is diagnosed by the presence of intense muscular pain and sudden elevation of total plasma levels of the enzyme creatine kinase (CK), with or without myoglobinuria, is closely associated with acute fatigue during exercise, as well to the associated risk of acute renal injury, disseminated intravascular coagulation, cardiac arrhythmias, and electrolyte disturbances. ER is highly prevalent in military training, particularly when performed in adverse climatic conditions, and many cases progress rapidly to acute, life-threatening renal failure. […]

With great interest on the topic, we read the article “The Profile of the Brazilian Cardiologist – A Sample of the Members of the Brazilian Society of Cardiology”, by Faganello et al., where the professional and personal characteristics of Brazilian cardiologists are reported. The significant gender differences were highlighted in the mini-editorial “Profile of Brazilian Cardiologists: A look on Female Leadership in Cardiology and Stress – Challenges for the Next Decade” by Mesquita et al., where peculiarities such as payment […]
