Arsenic exposure through drinking water is widespread and well-associated with adverse cardiovascular outcomes, yet the pathophysiological mechanisms by which inorganic arsenic (iAS) induces these effects are largely unknown. Recently, an epidemiological study in an American population with a low burden of cardiovascular risk factors found that iAS exposure was associated with altered left ventricular geometry. Considering the possibility that iAS directly induces cardiac remodeling independent of hypertension, we investigated the impact of an environmentally relevant iAS exposure on the structure and function of male and female hearts...

Ventricular dysfunction secondary to electrical and mechanical dyssynchrony in chronic right ventricular apical pacing is a well-recognized complication. There are no previous reports of pharmacologically induced dyssynchrony. A 10-day old infant with incessant supraventricular tachycardia was admitted to the neonatal intensive care unit. Therapy with oral propranolol was initiated and due to persistence of tachycardia intravenous amiodarone was administered. The patient remained predominantly in tachycardia with heart rates between 200-290 beats per minute for a week with serial echocardiograms showing preserved ventricular function...

OBJECTIVE: The ductus venosus, a small blood vessel in the fetal venous system, has extraordinary physiologic significance because it connects the umbilical vein to the inferior vena cava in the fetus circulation system and transports highly oxygenated blood from the placenta to the fetus' heart. Hence, assessment of ductus venosus flows is helpful in evaluating fetal hemodynamics. Considering the critical function of the ductus venosus, we hypothesized that the diameter of the midtrimester ductus venosus and its peak velocity index can be related to adequate fetal growth; therefore, the aim of this study was to evaluate the role of the midtrimester umbilical venous blood flow, ductus venosus diameter, and ductus venosus peak systolic velocity to help predict uncomplicated deliveries of late onset small for gestational age (SGA) fetuses...

AIMS: Hypertension (HTN) in pregnancy is a major cause of maternal, foetal and neonatal morbimortality in both developing and developed countries. Arterial stiffness is a predictor of cardiovascular events and can be assessed through augmentation index (AIx) and pulse wave velocity (PWV). This study was intended to analyse the arterial stiffness in three categories, hypertensive pregnant women vs. healthy women (both pregnant and non-pregnant). MAIN METHODS: Between 2018 and 2019, 150 women were prospectively included into three homogenous groups, of equal sizes (N = 50): pregnant women with HTN (group 1), pregnant women without HTN (group 2), and non-pregnant women (group 3)...

Myocardial fibrosis is a major determinant of clinical outcomes in heart failure (HF) patients. It is characterized by the emergence of myofibroblasts and early activation of pro-fibrotic signaling pathways before adverse ventricular remodeling and progression of HF. Boron has been reported in recent years to augment the innate immune system and cell proliferation, which play an important role in the repair and regeneration of the injured tissue. Currently, the effect of boron on cardiac contractility and remodeling is unknown...
