In 2016 the Journal of the American Medical Association published a theme issue on medical education, which included an editorial by Golub emphasizing the importance of looking backward on past to advance towards the future. Golub went on to say that the changes in society, such as the shifts in ethnicities, in cultural norms and in health care systems, will lead to new comprehensive, creative and innovative educational models to improve the quality of medical education and patient care. Therefore, […]

Background: In view of the increased global prevalence of cardiovascular and hepatic diseases, the diet lipid content and its relationship with the accumulation of fat in hepatocytes have been investigated as key factors in preventing these diseases. Objective: To evaluate the metabolic effects of a high-lard diet supplemented or not with cholesterol on a modified dyslipidemia model. Methods: We divided 24 adult male Wistar rats into three groups: standard diet (STD – 4% lipids), high-lard diet (HLD – 21% lard), […]

Background: Arterial hypertension is a precursor to the development of heart and renal failure, furthermore is associated with elevated oxidative markers. Environmental enrichment of rodents increases performance in memory tasks, also appears to exert an antioxidant effect in the hippocampus of normotensive rats. Objectives: Evaluate the effect of environmental enrichment on oxidative stress in the ventrolateral medulla, heart, and kidneys of renovascular hypertensive rats. Methods: Forty male Fischer rats (6 weeks old) were divided into four groups: normotensive standard condition […]

Background: Hepatopulmonary syndrome (HPS), found in cirrhotic patients, has been little studied in hepatosplenic schistosomiasis (HSS) and includes the occurrence of intrapulmonary vascular dilatations (IPVD). Contrast transesophageal echocardiography (cTEE) with microbubbles is more sensitive than contrast transthoracic echocardiography (cTTE) with microbubbles in the detection of IPVD in cirrhosis. Objective: To assess the performance of the cTEE, compared with that of cTTE, in detecting IPVD for the diagnosis of HPS in patients with HSS. Methods: cTEE and cTTE for investigation of […]

Background: D-limonene (DL) is a monoterpene and is the major component in the essential oil of citrus fruit. It presents antihyperglycemic and vasodilatation activities. Objectives: This study evaluated the cardiovascular effects and potential antiarrhythmic of DL in rats. Methods: Hemodynamic and electrocardiographic (ECG) parameters were measured in male Wistar rats, which under anesthesia had been cannulated in the abdominal aorta and lower vena cava and had electrodes subcutaneously implanted. In the in vitro approach, the heart was removed and perfused […]

Background: New echocardiographic techniques are used in the diagnosis and prognosis of many heart diseases. However, reference values in different populations are still needed for several of these new indexes. We studied these new echocardiographic parameters in a group of Brazilians with no known cardiovascular disease. Objective: To study values for new echocardiographic indexes in Brazilians without known cardiovascular disease and their correlation with age. Methods: Cross-sectional study that included healthy individuals who underwent three-dimensional echocardiography (3DE) and two-dimensional speckle […]

Backgrund: New-onset atrial fibrillation complicating acute myocardial infarction represents an important challenge, with prognostic significance. Objective: To study the incidence, impact on therapy and mortality, and to identify predictors of development of new-onset atrial fibrillation during hospital stay for ST-segment elevation myocardial infarction. Methods: We studied all patients with ST-elevation myocardial infarction included consecutively, between 2010 and 2017, in a Portuguese national registry and compared two groups: 1 – no atrial fibrillation and 2 – new-onset atrial fibrillation. We adjusted […]

Abstract Background: Coronary angiography with two catheters is the traditional strategy for diagnostic coronary procedures. TIG I catheter permits to cannulate both coronary arteries, avoiding exchanging catheters during coronary angiography by transradial access. Objective: The aim of this study is to evaluate the impact of one-catheter strategy, by avoiding catheter exchange, on coronary catheterization performance and economic costs. Methods: Transradial coronary diagnostic procedures conducted from January 2013 to June 2017 were collected. One-catheter strategy (TIG I catheter) and two-catheter strategy […]

Background: The diagnosis of arterial hypertension based on measurements of blood pressure in the office has low accuracy. Objective: To evaluate the prevalence of masked hypertension (MH) and white-coat hypertension through home blood pressure monitoring (HBPM) in pre-hypertensive and stage 1 hypertensive patients. Method: Retrospective study, of which sample consisted of individuals with BP ? 120/80 mmHg and < 160/100 mmHg at the medical office without the use of antihypertensive medication and who underwent exams on the HBPM platform by […]

Fabry Disease Fabry’s disease FD is a genetic, lysosomal storage disorder caused by total or partial alpha-galactosidase (α-Gal A) deficiency of the enzyme that degrades glycolipid globotriaosylceramide (Gb3) in lysosomes. Therefore Gb3 deposits accumulate in the endothelial cells and heart, resulting in organic dysfunction. The gene that causes FD is located in the long arm of the X chromosome (locus Xq22) and currently hundreds of pathogenic mutations have been described. Thus, male homozygous patients develop the classic disease, while female […]

Abstract Spontaneous coronary artery dissection (SCAD) is considered an often underdiagnosed acute coronary syndrome, with few cases described in literature. Its association with physical exercise among young patients without risk factors or atherosclerotic disease (CAD) is even rarer. For this reason, a study was conducted on the subject, describing the clinical conditions, conduct and evolution regarding the suspicion of spontaneous exercise-related coronary artery dissection in three young patients without risk factors or CAD. Clinical conditions varied, with predominant recurrent chest […]

Clinical Data A 14-year-old patient was asymptomatic in all routine postoperative evaluations and in full physical activity, compared to others. During this period, which began when the patient was 21 months old, due to the type A atrioventricular (AV) septal defect totally corrected, no cardiac murmur was heard, the cardiac area remained normal and did not require the use of specific medication. An Echocardiography showed no residual defects, normal heart cavities and no valve regurgitation. The defect was diagnosed from […]

Abstract Fistula from left internal mammary artery (LIMA) to pulmonary artery (PA) is rarely encountered in daily practice. In recent years, endovascular therapy options have emerged for the treatment of fistula formations and replaced with surgery. A 53-year-old man admitted to our outpatient clinic with symptoms of typical angina and shortness of breath despite optimal medical therapy. In his relevant history, he had a coronary artery bypass graft (CABG) operation in 2009 in which his LIMA was anastomosed to left […]

Presentation In due time, the Brazilian Society of Cardiology decided to create a guideline on telemedicine applied to cardiology, also known as telecardiology. According to the Pan American Health Organization (PAHO) and the World Health Organization (WHO), telemedicine is “The delivery of health care services, where distance is a critical factor, by all health care professionals using information and communication technologies for the exchange of valid information for diagnosis, treatment, and prevention of disease and injuries, research and evaluation, and […]
