Abstract Background: Coarctation of the aorta is a congenital segmental narrowing of the aortic arch with severe hemodynamic repercussions and increased cardiovascular mortality. Early surgical correction and life-time echocardiographic follow-up must be performed to improve prognosis. However, this goal has been challenged by high rates of underdiagnosis, which delay surgical correction, and by recoarctation in up to one third of operated patients. Objectives: The objectives of this study were: (i) to register the frequency of common clinical signs at diagnosis […]

Abstract Background: The association between Diabetes Mellitus (DM) and Infective Endocarditis (IE) is controversial in the literature, since many controversial results have been published. However, when evaluating specifically the evidence on IE and individuals with DM using insulin, we found only two observational studies that considered this variable, with discordant results regarding the prognosis and prevalence of Staphylococcus sp in insulin users compared to non-users. Despite the lack of evidence, in clinical practice the insulin use could be interpreted as […]

Background: Treatment of postoperative (PO) pain is essential after surgery, as it contributes to a faster rehabilitation. Assessment of PO pain after minimally invasive (MI) surgery has not been regularly addressed, especially when compared with median sternotomy (MS). Objective: This study aims to evaluate the intensity of thoracic pain in the PO period in patients subjected to MI surgery and MS. Methods: This study compared the intensity of thoracic pain in 34 patients subjected to minimally invasive (MI; n = […]

Background: The aim of this study was to evaluate the QoL of patients undergoing heart valve replacement using the SF-36 questionnaire, compare it between patients with mechanical prosthesis and patients with bioprosthesis, and correlate the results with sociodemographic variables. Objective: To assess the QoL of patients undergoing heart valve replacement and compare it between patients with bioprosthetic valves and patients with mechanical prosthetic valves. Methods: We included 36 consecutive patients (16 men) with a mean age of 51 years and […]

Background: Recently, a new HF entity, with LVEF between 40-49%, was presented to comprehend and seek better therapy for HF with preserved LVEF (HFpEF) and borderline, in the means that HF with reduced LVEF (HFrEF) already has well-defined therapy in the literature. Objective: To compare the clinical-therapeutic profile of patients with HF with mid-range LVEF (HFmrEF) with HFpEF and HFrEF and to verify predictors of hospital mortality. Method: Historical cohort of patients admitted with decompensated HF at a supplementary hospital […]

Background: Although associated with traditional cardiovascular risk factors, it is unclear whether obesity alone is associated with coronary artery disease (CAD). Objective: To investigate the role of obesity as a risk factor for CAD, defined by coronary computed tomography angiography (CCTA). Methods: This study retrospectively included 1,814 patients referred for CCTA in a hospital in São Paulo, from August 2010 to July 2012. CAD was identified by coronary calcium score and presence of coronary stenosis > 50%. Images were analyzed […]

Background: Despite the efficacy of vitamin K antagonists against stroke in patients with atrial fibrillation (AF), the underuse of this therapy is well documented. Objectives: To evaluate trends and predictors of oral anticoagulants utilization in patients with AF. Methods: Observational, retrospective, serial cross-sectional study between 2011-2016. Comparisons between groups were performed using the Student t, Mann-Whitney and Chi-square tests. Logistic regression was used to identify independent predictors of anticoagulation. A p value < 0.05 was considered significant. Results: A total […]

Background: Lung diseases and different forms of breathing may interfere with cardiac autonomic modulation (CAM). Objective: To compare CAM in individuals with chronic obstructive pulmonary disease (COPD) with healthy individuals during spontaneous breathing (SB) and controlled breathing (CB). Methods: Cross-sectional study involving 30 individuals selected by convenience, divided into COPD group (n = 19) and control group (CG; n = 12). All participants were submitted to heart beat recordings during five minutes at rest (SB) and another five minutes during […]

18-fluorine-fluorodeoxyglucose positron emission computed tomography (18F-FDG PET/CT) and singlephoton emission computed tomography (SPECT) using radiolabeled white blood cells (WBC) are non-invasive techniques widely used in the diagnosis of infections, like endocarditis. The aim of our paper was to provide a systematic review of the published data on the use of 18F-FDG PET/CT and SPECT in infective endocarditis (IE). A comprehensive literature search of the PubMed/ MEDLINE, Scopus, Embase and Cochrane library databases was conducted to find relevant published articles about […]

Introduction Interrupted aortic arch (IAA) occurs in three births per million, and accounts for approximately 1% of congenital heart diseases (CHDs).– The first case reported with these anomalies appears to be the one by Seidel in 1818. IAA is a severe form of CHD characterized by a lack of luminal continuity between the ascending and the descending thoracic aorta. The two most common associated cardiac anomalies are ventricular septal defect (90%) and patent ductus arteriosus (98%). Isolated IAA is very […]
