BACKGROUND Several cardiovascular diseases are characterized by an impaired O2 kinetic during exercise. The lack of a linear increase of Δoxygen consumption (VO2)/ΔWork Rate (WR) relationship, as assessed by expired gas analysis, is considered an indicator of abnormal cardiovascular efficiency. We aimed at describing the frequency of ΔVO2/ΔWR flattening in(More)
OBJECTIVES Right ventricular (RV) exercise contractile reserve (RVECR), its phenotypes, and its functional correlates are among the unresolved issues with regard to the role of the right ventricle in heart failure (HF) syndrome, and understanding these issues constitutes the objective of this study. BACKGROUND Although the role of the right ventricle in(More)
INTRODUCTION There has been a greater appreciation of several variables obtained by cardiopulmonary exercise testing (CPX). Exercise oscillatory ventilation (EOV) is a CPX pattern that has gained recognition as an ominous marker of poor prognosis in cardiac patients. The purpose of the present study is to characterize whether such an abnormal ventilatory(More)
Aims In heart failure patients with reduced ejection fraction (HFrEF), exercise-induced functional mitral regurgitation (MR) may affect functional capacity and outcome. We sought to study functional and cardiac phenotypes of HFrEF patients according to the MR degree. Methods and results We performed rest and exercise echocardiography (Ex-Echo),(More)
OBJECTIVES The hypothesis of this study was that left atrial (LA) dynamic impairment during exercise may trigger right ventricular (RV)-to-pulmonary circulation (PC) uncoupling and ventilation inefficiency. BACKGROUND LA function plays a key role in the hemodynamics of heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved(More)
