Mitigating effect of tanshinone IIA on ventricular remodeling in rats with pressure overload-induced heart failure

Acta cir. bras; 34 (8), 2019
Abstract Purpose To investigate the effect of tanshinone IIA (TIIA) on ventricular remodeling in rats with pressure overload-induced heart failure. Methods Pressure overload-induced heart failure model (abdominal aortic coarctation) was established in 40 rats, which were divided into model and 5, 10 an...

Alprostadil attenuates myocardial ischemia/reperfusion injury by promoting antioxidant activity and eNOS activation in rats

Acta cir. bras; 33 (12), 2018
Abstract Purpose: To investigate the effect of alprostadil on myocardial ischemia/reperfusion (I/R) in rats. Methods: Rats were subjected to myocardial ischemia for 30 min followed by 24h reperfusion. Alprostadil (4 or 8 μg/kg) was intravenously administered at the time of reperfusion and myocar...

Estimulación del ventrículo derecho como causante y agravante de disincronía ventricular

Rev. costarric. cardiol; 20 (2), 2018
Resumen Introducción y objetivos . La activación eléctrica artificial del corazón en pacientes con arcapasos implantados en el ventrículo derecho es causante de disincronía ventricular. Synchromax® es un monitor de electrocardiografía que com prueba de manera no invasiva e instantánea el grado ...

Biventricular arrhythmogenic cardiomyopathy: a new paradigm?

Arrhythmogenic right ventricular dysplasia is a classic form of chronic myocardial disease with a broad phenotypical spectrum. We report an atypical case of a patient with biventricular arrhythmogenic cardiomyopathy. Although the current diagnosis criteria are the most widely accepted ones, they focus s...

Terapias Inapropiadas por defecto del electrodo Sprint Fidelis 6948® en un paciente con miocardiopatía arritmogénica del ventrículo derecho (MAVD) en Costa Rica, reporte del primer caso

Rev. costarric. cardiol; 20 (supl.1), 2018
Resumen Los avances en los dispositivos de desfibrilación automática implantable para pacientes que requieren este tipo de terapia han llevado a los fabricantes a intentar manofacturar componentes cada vez más modernos. En este sentido la compañía Medtronic intentó fabricar un electrodo más versá...

The artery of Mouchet: blood supply of the septomarginal trabecula in 50 human hearts

SUMMARY The septomarginal trabecula is a muscular structure which transmits the right branch of the atrioventricular bundle. It is usually supplied by a branch from the second anterior septal artery. Anastomoses between the right and left coronary arteries may happen on the septomarginal trabecula. They ...

Entrenamiento físico de alta intensidad en maratonistas produce mayor remodelado cardíaco y reduce respuesta de estrés oxidativo

Rev. chil. cardiol; 37 (2), 2018
Resumen: Introducción: El ejercicio físico reduce la mortalidad cardiovascular y genera remodelado cardíaco. Altas cargas de entrenamiento pueden generar remodelado cardíaco adverso. Biomarcadores (BMC) de inflamación Interleukina 6 (IL-6) y de estrés oxidativo Malondialdehído (MDA), potencialmen...

Ebstein's anomaly: "The one and a half ventricle heart"

Abstract Objective: Ebstein's anomaly remains a relatively ignored disease. Lying in the 'No Man's land' between congenital and valve surgeons, it largely remains inadequately studied. We report our short-term results of treating it as a 'one and a half ventricle heart' and propose that the true tricusp...

Correlations of inhaled NO with the cTnI levels and the plasma clotting factor in rabbits with acute massive pulmonary embolism

Acta cir. bras; 33 (8), 2018
Abstract Purpose: To investigate the correlation of inhaled nitric oxide (NO) on plasma levels of cardiac troponin I (cTnI) and von Willebrand factor (vWF), glycoprotein (GP) IIb/IIIa, granule membrane protein 140 (GMP-140) in rabbits with acute massive pulmonary embolism (PE). Methods: Thirty apanese...
