Abstract Background Hemodynamic assessment can be determinant in phenotyping cardiogenic shock (CS) and guiding patient management. Aim of this study was to evaluate the correlation between echocardiographic and invasive assessment of hemodynamics in acute decompensated heart failure-related CS (ADHF-CS). Methods All consecutive ADHF-CS patients (SCAI shock stage ≥B) undergoing right heart catheterization (RHC) between 2020 and 2022 were prospectively enrolled. Patients underwent echocardiography 30 minutes before RHC. The evaluated hemodynamic parameters and their echocardiographic estimates (“e”) comprised cardiac index (CI), wedge pressure (WP), pulmonary artery pressures (PAP), cardiac power output (CPO) and pulmonary artery pulsatility index (PAPi). Results 101 ADHF-CS patients (56±11 years, 64% SCAI shock stage C, left ventricular ejection fraction 29±5%) were included. Good correlation was found for CI, systolic PAP, RAP and CPO (Pearson r > 0.8 for all), moderate correlation for ePAPi (r=0.67) and PVR (r=0.51), while estimation of WP was weak. The sensitivity and specificity of eCI to identify low output state (CI ≤2.2 l/min/m2) were 0.97 and 0.73 respectively, those of eWP for elevated filling pressures (WP >15 mmHg) were 0.84 and 0.55, those of ePAPs for PAPs ≥35 mmHg were 0.87 and 0.63, those of eCPO for CPO<0.6 W were 0.76 and 0.85, those of ePAPi for PAPi <1.85 were 0.89 and 0.92. Echocardiographic phenotyping of CS showed a good agreement with invasive classification (K value 0.457, p<0.001). Conclusions Echocardiographic estimation of hemodynamics and subsequent phenotypization of CS is feasible with good agreement with invasive evaluation.
