الوصف: | Abstract Periodic repetition of right heart catheterization (RHC) in pulmonary arterial hypertension (PAH) can be challenging. We evaluated the correlation between RHC and cardiopulmonary exercise test (CPET) aiming at CPET use as a potential noninvasive tool for hemodynamic burden evaluation. One hundred and forty‐four retrospective PAH patients who had performed CPET and RHC within 2 months were enrolled. The following analyses were performed: (a) CPET parameters in hemodynamic variables tertiles; (b) position of hemodynamic parameters in the peak end‐tidal carbon dioxide pressure (PETCO2) versus ventilation/carbon dioxide output (VE/VCO2) slope scatterplot, which is a specific hallmark of exercise respiratory abnormalities in PAH; (c) association between CPET and a hemodynamic burden score developed including mean pulmonary arterial pressure (mPAP), pulmonary vascular resistance (PVR), cardiac index, and right atrial pressure. VE/VCO2 slope and peak PETCO2 significantly varied in mPAP and PVR tertiles, while peak oxygen uptake (peak VO2) and O2 pulse varied in the tertiles of all hemodynamic parameters. PETCO2 versus VE/VCO2 slope showed a strong hyperbolic relationship (R2 = 0.7627). Patients with peak PETCO2 > median (26 mmHg) and VE/VCO2 slope < median (44) presented lower mPAP and PVR (p median. Multivariate analysis individuated peak VO2 (p = 0.0158) and peak PETCO2 (p = 0.0089) as hemodynamic score independent predictors; the formula 11.584 − 0.0925 × peak VO2 − 0.0811 × peak PETCO2 best predicts the hemodynamic score value from CPET data. A significant correlation was found between estimated and calculated scores (p |
