25. Late cardiac perconditioning by phenylephrine in an isolated rat heart model is mediated by mitochondrial potassium channels
The present study was designed to investigate the effect of early and late administration of phenylephrine during ischemia against regional ischemia-reperfusion injuries in an isolated rat heart model. All animals were randomly divided into experimental groups: (I) IR (Ischemic/ reperfusion): the hearts underwent 35 min of regional ischemia followed by 60 mi

26. Prognostic value of coupling interval, prematurity index and heart rate variability in Boxer dogs
RESUMO: Cães da raça Boxer com cardiomiopatia arritmogênica do ventrículo direito (CAVD) podem apresentar morte súbita independentemente da presença/ausência de sinais clínicos. Os objetivos desse estudo retrospectivo foram: 1) investigar o intervalo de acoplamento (IA) e o índice de prematuridade (IP) das arritmias ventriculares e a variabilidade d

27. QT Dispersion Changes after Transcatheter Aortic Valve Implantation in Patients with Aortic Stenosis
Abstract Objective: The aim of this study was to evaluate the QT dispersion and echocardiographic parameters in patients before and after transcatheter aortic valve implantation (TAVI). Methods: One hundred and fifty-two patients with severe aortic valve stenosis (AS) were included in our study. Ninety five patients who underwent aortic valve replacement w

28. Sudden Cardiac Death in Sports: Why Its Prevalence is So Different by Gender?
Abstract Sports competition can be a trigger to fatal arrhythmias in predisposed individuals, leading to sudden cardiac death. Athletes have 2.8 fold more risk of sudden cardiac death than non-athletes. However, female athletes seem to have some cardiac protection, dying suddenly much less than men during sports. Although the mechanisms for this protection h

29. Update on Sports Participation for Athletes with Implantable Cardioverter Defibrillators
Abstract Prior statements have recommended restriction from competitive sports participation for all athletes with ICDs. Recent data, however, suggests that many athletes can participate in sports without adverse events. In the ICD Sports Registry, 440 athletes, aged 8-60 years, 77 of which were high-level interscholastic athletes, who had continued to pract

30. Cardiopulmonary Exercise Testing in Patients with Implantable Cardioverter-Defibrillator: A Retrospective Study
Abstract Background: Cardiopulmonary exercise testing is widely used in the evaluation of patients with left ventricular dysfunction, and some of these patients have an implantable cardioverter-defibrillator (ICD). However, this test presents specific challenges because of the susceptibility to ventricular arrhythmias during maximal levels of exercise. Obj

31. An Easy and Reliable Way to Prevent Electrocardiographic Deteriorations of Patients Undergoing Off-Pump Coronary Artery Bypass Surgery: Preoperative Anxiolytic Treatment
Abstract Objective: To investigate the effects of preoperative anxiety relieving on electrophysiological changes in patients undergoing off-pump coronary artery bypass surgery. Methods: A total of 61 patients at ASA III risk group in the age range of 18-65 years were enrolled in the present study. Patients were randomly divided into two groups. Group S (Se

32. Non-invasive ECG recording and QT interval correction assessment in anesthetized rats and mice
RESUMO: Ratos e camundongos são as espécies mais comumente utilizadas em estudos experimentais de eletrofisiologia cardíaca. O registro do eletrocardiograma (ECG) é de suma importância para o monitoramento de arritmias e função cardíaca em vários modelos de patologias. No entanto, a falta de valores de referência padronizados e a fórmula de corre�

34. The Kidney in Fabry Disease: More Than Mere Sphingolipids Overload
Abstract Fabry disease is a rare cause of end-stage renal disease. Renal pathology is notable for diffuse deposition of glycosphingolipid in the renal glomeruli, tubules, and vasculature. Classical patients with mutations in the α-galactosidase A gene accumulate globotriaosylceramide and become symptomatic in childhood with pain, gastrointestinal disturbanc

35. Cardiac Manifestation of Fabry Disease: From Hypertrophic Cardiomyopathy to Early Diagnosis and Treatment in Patients Without Left Ventricular Hypertrophy
Abstract Although Fabry disease was identified a century ago, it is still a challenging condition to diagnose and treat. Registries data suggest that at least 10% of patients may first present with a cardiac event and that cardiac disease is 1 of the 3 major causes of morbidity and mortality in affected males and females. Cardiac involvement in Fabry disease

36. Left ventricular noncompaction in a Para athlete
RESUMO O miocárdio não compactado é uma cardiomiopatia congênita caracterizada pela presença de trabeculações anormais no ventrículo esquerdo. O presente estudo descreve o caso de uma paratleta de goalball, 14 anos, sexo feminino, assintomática, com história pessoal de nistagmo congênito e leve deficiência visual, que apresentou alterações elet
