1. 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

2. Proadrenomedullin in Patients with Preserved Left Ventricular Systolic Function Undergoing Coronary Artery Bypass Grafting
Abstract Introduction: A potentially new marker of cardiovascular diseases — proadrenomedullin is the precursor of adrenomedullin, which is a multifunctional peptide hormone, produced in most of the tissues in response to cellular stress, ischemia, and hypoxia. Methods: Ninety-three people, aged 51-79 years, were included in the study. Exclusion criteria

3. When an Implantable Cardioverter Defibrillator can Kill your Patient!
Abstract Inappropriate therapy due to noise oversensing caused a true ventricular fibrillation (VF) and a life-threatening event in a patient. A 19-year-old patient with surgically corrected congenital heart disease and systolic dysfunction had an implantable cardioverter defibrillator implanted for primary prevention in 2013. This patient was admitted at th

4. Frontal plane QRS-T angle may be a predictor for post-coronary artery bypass graft surgery atrial fibrillation
RESUMO OBJETIVO: A fibrilação atrial pós-operatória de início recente (Poaf) é a arritmia mais comum após a cirurgia de revascularização do miocárdio (CABG) e associada a hospitalização prolongada, acidente vascular cerebral e mortalidade. O ângulo QRS-T [f(QRS-T)] do plano frontal, que é definido como o ângulo entre as direções da despolar

5. Translational Approach for Percutaneous Interventions for the Treatment of Cardiac Arrhythmias
Abstract New translational concepts on cellular and tissue substrate of cardiac arrhythmias have been responsible for the development of non-pharmacological interventions, with important achievements compared to the conventional approach with antiarrhythmic drugs. In addition, the increasing knowledge of anatomical and electrophysiological studies, sophistic

6. Association between Mean Platelet Volume-to-Lymphocyte Ratio and the Presence of Apical Mural Thrombus in Post-Myocardial Infarction Patients
Abstract Background Left ventricular apical thrombus (AT) is generally associated with ischemic and non-ischemic cardiomyopathies. The thrombo-inflammatory process plays an important role in the pathophysiology of acute coronary syndromes and post-myocardial thromboembolic complications. Mean platelet volume (MPV) has been linked to poor prognosis followin

7. Predictors of left atrial thrombus in acute ischemic stroke patients without atrial fibrillation: A single-center cross-sectional study
RESUMO INTRODUÇÃO: O presente estudo teve como objetivo determinar indicadores independentes do trombo auricular esquerdo (LAT) em doentes com acidente vascular cerebral isquêmico agudo (AIS) sem fibrilação auricular (AF) utilizando ecocardiografia transesofágica (TEE). MÉTODOS: Neste único centro, estudo retrospectivo, inscrevemos 149 pacientes co

8. Enhanced external counterpulsation improves cardiac function in Beagles after cardiopulmonary resuscitation
The aim of this study was to investigate the influence of enhanced external counterpulsation (EECP) on the cardiac function of beagle dogs after prolonged ventricular fibrillation. Twenty-four adult male beagles were randomly divided into control and EECP groups. Ventricular fibrillation was induced in the animals for 12 min, followed by 2 min of cardiopulmo

9. Challenges in Diagnosis and Management of Spontaneous Coronary Artery Dissection in a Young Patient
Abstract Spontaneous coronary artery dissection (SCAD) is characterized by tear of the inner layer in the coronary artery, creating a false lumen between the inner and central layer. Its infrequent incidence often leads to delay in diagnosis posing challenges in management. There are currently no guidelines for the treatment of this condition. We describe an

10. Predictive value of ATRIA risk score for contrast-induced nephropathy after percutaneous coronary intervention for ST-segment elevation myocardial infarction
RESUMO OBJETIVO: O escore Anticoagulação e Fatores de Risco na Fibrilação Atrial (Atria), usado na detecção do risco tromboembólico e hemorrágico de pacientes com fibrilação atrial (FA), recentemente demonstrou predizer resultados clínicos ruins em pacientes com infarto agudo do miocárdio (SCA), independentemente de ter FA.

11. The Relationship Between Mitral Annular Calcification, Metabolic Syndrome and Thromboembolic Risk
Abstract Introduction: Metabolic syndrome (MetS) is defined as an association between diabetes, hypertension, obesity and dyslipidemia and an increased risk of cardiovascular disease. Mitral annular calcification (MAC) is associated with several cardiovascular disorders, including coronary artery disease, atrial fibrillation (AF), heart failure, ischemic st

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
