Pulmonary arterial hypertension (PAH) is a life-threatening disease characterized by a progressive increase in pulmonary artery pressure and pulmonary vascular resistance, leading to right ventricular failure and death.1 The recent World Health Organization (WHO) classification designates PAH as Group I and includes idiopathic PAH (IPAH)—formerly known as primary pulmonary hypertension (PPH)…

Hypertension (HT) remains the most common preventable risk factor for cardiovascular (CV) morbidity and mortality. There are exciting new data about epidemiology, brachial blood pressure (BP), ambulatory blood pressure monitoring (ABPM) and pre-hypertension from large clinical trials.
Increasing Burden of Hypertension Worldwide
The incidence of HT is rising worldwide due to common environmental…

Fetal and neonatal arrhythmias are diverse in type and severity. They include both tachycardias and bradycardias.1 The innate physiological properties of the fetal and neonatal myocardium make it more vulnerable to these high or low ventricular rates. Irregularities of fetal and neonatal cardiac rhythm commonly occur and rarely have serious consequences;however, it is important to realize that…

Pulmonary hypertension (PH) is a hemodynamic condition defined by pulmonary arterial systolic pressure (PASP) above an upper limit of 35mmHg, or by pulmonary arterial mean pressure (PAMP) exceeding 25mmHg at rest.1,2 Pulmonary arterial hypertension (PAH) is present when pre-capillary pulmonary vascular pressure is elevated in the absence of pulmonary capillary wedge pressure >15mmHg, such as…

Fetal tachyarrhythmias occur in approximately 0.4-0.6% of all fetuses.1-3 Normal fetal heart rates range from 120-160 beats per minute (bpm), with rates greater than 180bpm indicative of tachycardia.4-7 Usually, fetal arrhythmias are isolated findings; however, 5% of fetuses will also have congenital heart disease,8,9 such as Ebstein's anomaly, atrioventricular canal, hypoplastic left heart…

After a drought in viable new therapies for more than a decade, two new drugs for use in heart failure patients were approved by the US Food and Drug Administration (FDA) in 2015. These drugs represent two new classes of agents in the heart failure space: a combined angiotensin receptor-neprilysin inhibitor (ARNI) (sacubitril/valsartan; brand name Entresto®, Novartis) and a sinoatrial node…

The pump function of the heart resides on two main abilities that allow the entire organism to cope with and face different physiological circumstances from sleep to intense physical exercise of sport activities:
a) diastolic function, defined as the ability of the ventricles to relax and to accept the normal stroke volume at the low pressures existing in the systemic and pulmonary veins; and

The approach to the treatment of a variety of cardiovascular disorders has undergone remarkable change over the past two decades. The use of both percutaneous interventions in patients with acute myocardial infarction and automatic implantable cardiodefibrillators in patients with ventricular arrhythmias represent important examples. The cardiology community is currently in the process of another…

Introduction
Strictly speaking, there are no arrhythmias that are specific to women. However, as with most diseases, the diagnosis of arrhythmias presents unique challenges when applied to women. Women have distinct symptoms, different etiologies and incidences of arrhythmias, and even differing outcomes compared with men.
This article will discuss both the benign and more malignant arrhythmias…
