Abstract Background In the pediatric population, syncope is mainly from vasovagal (VVS) origin. Its evaluation must be done by clinical methods, and the tilt test (TT) can contribute to the diagnosis. Objectives To analyze the clinical profile, Calgary and modified Calgary scores, response to TT and heart rate variability (HRV) of patients aged ≤ 18 years with presumed VVS. To compare the variables between patients with positive and negative responses to TT. Method Observational and prospective study, with 73 patients […]

Abstract Background The transthoracic echocardiogram (TTE) plays a screening role in the diagnostic algorithm of pulmonary hypertension (PH). Studies have shown a significant disagreement between TTE measurements of the systolic pulmonary artery pressure (sPAP) and right atrial pressure (RAP) and those obtained by right heart catheterization (RHC). Objective To compare TTE measurements of sPAP and RAP with those obtained by RHC in patients being investigated for PH. Methods Patients referred to a PH reference center with a high or intermediate […]

Abstract Background Sarcopenia is highly prevalent in heart failure (HF) patients, and the involvement of biomarkers in its pathophysiology is suggested, but little has been studied concerning HF sarcopenic patients. Objectives To evaluate the association between inflammatory and humoral markers with sarcopenia, as well as the impact of sarcopenia on quality of life and functional capacity in older HF patients. Methods In this cross-sectional study, 90 outpatient HF patients, aged ≥ 60 years, were evaluated for sarcopenia (EWGSOP2 diagnostic criteria), […]

Abstract Background The extent of cardiac damage associated with aortic stenosis has important prognostic implications after transcatheter aortic valve replacement (TAVR). However, the role of tricuspid regurgitation (TR) in this clinical setting is still unclear. Objectives To explore the association between TR and mortality in patients undergoing TAVR and assess changes in TR severity post TAVR and its relationship with short and mid-term mortality. Methods Relevant databases were searched for articles published from inception until August 2020. Out of 414 […]

Abstract Background For practical and protective ventilation during cardiopulmonary resuscitation (CPR), a 150-grams mechanical ventilator (VLP2000E) that limits peak inspiratory pressure (PIP) during simultaneous ventilation with chest compressions was developed. Objectives To evaluate the feasibility of VLP2000E ventilation during CPR and to compare monitored parameters versus bag-valve ventilation. Methods A randomized experimental study with 10 intubated pigs per group. After seven minutes of ventricular fibrillation, 2-minute CPR cycles were delivered. All animals were placed on VLP2000E after achieving return of […]

Our planet is facing an unprecedented crisis related to climate change and the loss of biodiversity, and there is evidence that this crisis has threatened the health of our ecosystems and communities, in addition to modifying the lifestyle of living beings on Earth. Moreover, multiple scientists have stated that “we have years rather than decades to fight this crisis.” Since elementary school, we learn about the importance of oxygen for human life. It is estimated that 50% to 80% of […]

Introduction The cellular integrity of myocardial tissue is crucial information to evaluate the viability of the heart. Cardiac magnetic resonance imaging (CMR) is considered the gold standard method for functional analysis of the heart, and it plays an essential role in the diagnosis of several cardiomyopathies, including myocardial infarction. When there is a failure in the energy supply of heart cells, there occurs a decrease in blood flow in certain regions, which can lead to cell death. CMR can assess […]

Introduction Persistent monosytic pacing of the right ventricle can cause deleterious effects on ventricular function. Patients with Chagas cardiomyopathy (CCM) with ventricular dysfunction, requiring artificial heart stimulation (AHS) may accelerate the progression to heart failure (HF) due to the underlying disease and the consequent ventricular dyssynchrony. For over 20 years, cardiac resynchronization therapy (CRT) has been an established alternative in cardiology for the treatment of heart failure with reduced ejection fraction (LVEF) with intraventricular conduction disorder (especially LBBB)., However, the […]

Introduction Depression is a global disease affecting around 330 million people, corresponding to 4.4% of the global population, and is the second cause of incapacitation in the USA. In Brazil, it is estimated that 5.8% of the population, 11 million people, suffer from this disease, placing the country first in Latin America and the second in the Americas considering the number of cases. In addition, the data published by the National Health Survey (PNS) conducted in 2013 verified that 78.8% […]

Abstract Emery-Dreifuss muscular dystrophy is a rare hereditary neuromuscular disease. Its manifestations begin primarily in childhood. The most frequent manifestations are progressive muscle weakness, atrophy that usually begins in the scapula-vertebral region, extending later to the pelvic girdle, and spinal stiffness. Patients can also manifest cardiac involvement as palpitations, syncope, exercise intolerance, congestive heart failure, and variable heart rhythm disturbances. – The presence and severity of these manifestations can vary according to the individual and the disease’s subtypes. Cardiac involvement […]

Abstract The final months of 2019 saw the emergence of a new pandemic termed “COVID-19”. Since then, this infection and its complications have been the priority of healthcare providers, with many symptoms attributed to its early and late presentations. Thus far, other diseases, even fatal situations, have been overlooked or misdiagnosed due to the attribution of patient symptoms to the presence of COVID-19 infection. We herein present a case of cardiac angiosarcoma in a young boy who had previously become […]

Isolated coronary artery ectasia (ICAE) is frequently encountered in clinical practice with increasing invasive imaging methods, and our knowledge about its etiology, prognosis, and treatment approaches is increasing daily., We read with great interest the recent retrospective study of Dindas et al., which deals with the relationship between the Systemic Immune Inflammation Index (SII) and ICAE. It has been suggested that SII neutrophils, platelets, and lymphocytes collected in a single fraction may be a good indicator of inflammation and immune […]
