Background and Purpose: The diverse causes of right-sided heart failure (RHF) include,
among others, primary cardiomyopathies with right ventricular (RV) involvement, RV …

Compared with traditional exercise tests, cardiopulmonary exercise testing (CPET) provides
a thorough assessment of exercise integrative physiology involving the pulmonary …

In the past several decades, cardiopulmonary exercise testing (CPX) has seen an
exponential increase in its evidence base. The growing volume of evidence in support of …

There is an unmet need for effective treatment strategies to reduce morbidity and mortality in
patients with heart failure with preserved ejection fraction (HFpEF). Until recently, attention in …

Pulmonary hypertension is a common hemodynamic complication of heart failure. Interest in
left-sided pulmonary hypertension has increased remarkably in recent years because its …

Background The ratio of echocardiography-derived tricuspid annular plane systolic
excursion (TAPSE) and pulmonary arterial systolic pressure (PASP) has recently been …

Objectives This study sought to assess the impact of right ventricular dysfunction (RVD) as
defined by impaired right ventricular-to-pulmonary artery (RV-PA) coupling, on survival after …

Increased pulmonary venous pressure secondary to left heart disease is the most common
cause of pulmonary hypertension (PH). The diagnosis of PH due to left heart disease relies …

Objectives: The hypothesis of this study was that left atrial (LA) dynamic impairment during
