Cardioprotective effect of preconditioning is more efficient than postconditioning in rats submitted to cardiac ischemia and reperfusion

Acta cir. bras; 33 (7), 2018
Abstract Purpose: To investigate the cardioprotective effects of ischemic preconditioning (preIC) and postconditioning (postIC) in animal model of cardiac ischemia/reperfusion. Methods: Adult rats were submitted to protocol of cardiac ischemia/reperfusion (I/R) and randomized into three experimental g...

Update in heart rhythm abnormalities and indications for pacemaker after transcatheter aortic valve implantation

Abstract Objective: Rhythm abnormalities following transcatheter aortic valve implantation (TAVI) and indications for permanent pacemaker implantation (PPI) were reviewed, which aren't well established in the current guidelines. New left bundle branch block and atrioventricular block are the most common ...

Is There any Relationship Between Myocardial Repolarization Parameters and the Frequency of Ventricular Premature Contractions?

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: Ventricular premature contractions (VPCs) may trigger lethal ventricular arrhythmias in patients with structural heart disease. However, this role of VPCs in healthy people remains controversial once that not enough clinical trials are available. Recently, some myocardial repolariza...

Prevention of Sudden Cardiac Death in Hypertrophic Cardiomyopathy: What has Changed in The Guidelines?

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: The new European Society of Cardiology guidelines for hypertrophic cardiomyopathy (HCM) define the estimation of sudden cardiac death (SCD) risk as an integral part of clinical management. An implantable cardioverter defibrillator (ICD) is recommended (class IIa) when the risk is &#...

Cardioprotective effect of lipstatin derivative orlistat on normotensive rats submitted to cardiac ischemia and reperfusion

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To evaluate in vivo animal model of cardiac ischemia/reperfusion the cardioprotective activity of pancreatic lipase inhibitor of the orlistat. Methods: Adult male Wistar rats were anesthetized, placed on mechanical ventilation and underwent surgery to induce cardiac I/R by obstructin...

QRS-fragmentation: Case report and review of the literature

Arch. cardiol. Méx; 88 (2), 2018
Abstract Fragmentation of QRS complex (QRSf) is an easily evaluable, non-invasive electrocardiographic parameter that represents depolarisation anomalies and has been associated with several adverse outcomes, such as sudden death, fibrosis, arrhythmic burden, and a worse prognosis in different conditions...

Segunda publicación nuevos anticoagulantes orales: guía práctica para los médicos

Rev. costarric. cardiol; 20 (1), 2018
Resumen Los nuevos anticoagulantes orales suponen una atractiva alternativa para los clásicos antagonistas de la vitamina K (AVKs) en la prevención de ictus en pacientes con fibrilación auricular no valvular. A diferencia de los AVKs, estos anticoagulantes no requieren monitorización ni ajuste de dos...

Distres respiratorio agudo post aislamiento percutáneo de venas pulmonares

Rev. costarric. cardiol; 20 (1), 2018
Resumen Paciente de 48 años con historia de fibrilación auricular paroxística, dislipidemia y antecedente de ablación de vía accesoria (2013). Anti coagulado con Rivaroxaban 20 mg PO. Paciente es llevado a aislamiento percutáneo de venas pulmonares (AVP) con sistema de navegación tridimensional Ca...

Association between Microvolt T-Wave Alternans and Malignant Ventricular Arrhythmias in Chagas Disease

Arq. bras. cardiol; 110 (5), 2018
Abstract Background: Sudden cardiac death is the most frequent death mechanism in Chagas disease, responsible for 55% to 65% of the deaths of patients with chronic Chagas cardiomyopathy (CCC). The most often involved electrophysiological mechanisms are ventricular tachycardia and ventricular fibrillatio...
