Right-ventricle heart failure in PAH vs. HFrEF with secondary PH: Hemodynamic, ergospirometric, and organ function correlations.

Purpose: The goal of the study was to identify markers of organ function used in daily routines that could potentially aid in the overall evaluation of the cardiovascular system in patients with right-ventricle heart failure due to pulmonary arterial hypertension (PAH) and left-ventricle heart failure. We analyzed correlations between parameters from right heart catheterization (RHC), cardiopulmonary exercise test (CPET), and selected laboratory parameters of thyroid, liver, kidneys function and iron homeostasis.

Patients And Methods: A retrospective analysis included 107 patients (mean age 57.
