1. É sempre necessário solicitar um eletrocardiograma antes de prescrever um antidepressivo tricíclico?
Não há necessidade absoluta de solicitar eletrocardiograma (ECG) antes de prescrever um antidepressivo tricíclico. Pacientes sem fatores de risco para morte súbita e em uso de doses baixas de tricíclicos (abaixo de 100 mg/dia de amitriptilina, imipramina e clomipramina e abaixo de 62,5 mg/dia de nortriptilina,) não necessitam realizar um ECG antes d

2. Short-Term Results of Ivabradine versus Metoprolol: The Effects on Atrial Fibrillation in Patients Undergoing Off-Pump Coronary Artery Bypass Grafting
ABSTRACT Introduction: Classic coronary artery bypass grafting (CABG) surgery involves diastolic cardiac arrest under cardiopulmonary bypass, while off-pump CABG (OPCABG) has become widespread in recent years. Methods: 174 patients who underwent OPCABG were included in the study. Patients were divided into two groups. Group I (n=90) received ivabradine and

3. The Association between Tp-e interval, Tp-e/QT , and Tp-e/QTc Ratios and Coronary Artery Disease Spectrum and Syntax Score
Abstract Background Coronary artery disease (CAD) causes electrical heterogeneity on ventricular myocardium and ventricular arrhythmia due to myocardial ischemia linked to ventricular repolarization abnormalities. Objective Our aim is to investigate the impact of increased level of CAD spectrum and severity on ventricular repolarization via Tp-e interval

6. The Effect of High-Dose Vitamin C on Biochemical Markers of Myocardial Injury in Coronary Artery Bypass Surgery
Abstract Objective: To evaluate the effect of high-dose vitamin C on cardiac reperfusion injury and plasma levels of creatine kinase-muscle/brain (CK-MB), troponin I, and lactate dehydrogenase (LDH) in patients undergoing coronary artery bypass grafting (CABG). Methods: This is a double-blind randomized clinical trial study. Fifty patients (50-80 years old

7. Outbreaks of nutritional cardiomyopathy in pigs in Brazil
RESUMO: Cardiomiopatia dilatada (CMD) é uma condição que afeta o miocárdio, raramente relatada em porcos. A DCM é caracterizada por dilatação ventricular, que resulta em disfunção sistólica e disfunção diastólica secundária e pode levar a arritmias e insuficiência cardíaca congestiva fatal. Este estudo descreve os achados clínicos, patológi

8. Bradycardic and Antiarrhythmic Effects of the D-Limonene in Rats
Resumo Fundamento: O D-limoneno (DL) é um monoterpeno e o principal componente do óleo essencial de frutas cítricas. Ele apresenta atividades anti-hiperglicêmicas e vasodilatadoras. Objetivos: Este estudo avaliou os efeitos cardiovasculares e antiarrítmicos potenciais do DL em ratos. Métodos: Os parâmetros hemodinâmicos e eletrocardiográficos (EC

9. Fatores de risco associados à mortalidade hospitalar em reoperação valvar mitral
RESUMO Objetivo: identificar os fatores associados à mortalidade em reoperação valvar mitral, criar um modelo preditivo de mortalidade e avaliar o EuroSCORE. Métodos: foram avaliados 65 pacientes submetidos à reoperação de valva mitral no período de janeiro de 2008 a dezembro de 2017. Foi verificada a associação das variáveis com o óbito e cria

10. 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

11. 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

12. Left Atrial Size Contribution to the Predictive Capacity of Two Scores for Atrial Fibrillation in the Postoperative Period of Cardiac Surgeries
Abstract Background: Postoperative atrial fibrillation (POAF) is a common complication associated with undesirable outcomes; hence, the provision of appropriate tools is important to help identify patients at risk. Objectives: To evaluate the predictive capacity of the CHADS2 and CHA2DS2-VASc scores, alone and combined with left atrial (LA) size, for the o
