Key result
Echo parameters correlate poorly with PAC-derived RAP in ischemic cardiogenic shock.
Why the study?
Accurate estimation of right atrial pressure is crucial in cardiogenic shock, yet echocardiographic surrogates are often unreliable.
Do right heart echocardiographic indices accurately correlate with pulmonary artery catheter-derived right atrial pressure in patients with ischaemic cardiogenic shock?
Observational (n=43)
Do right heart echocardiographic indices accurately correlate with pulmonary artery catheter-derived right atrial pressure in patients with ischaemic cardiogenic shock?
Effect estimate: rho = 0.31
p-value: p=0.04
Conventional echocardiographic indices correlate poorly with invasive right atrial pressure and cannot reliably substitute for pulmonary artery catheterization to assess venous congestion in ischaemic cardiogenic shock.
Echocardiography cannot substitute for PAC to assess venous congestion in ischaemic cardiogenic shock; challenges utility of conventional right heart indices.
Accurate estimation of right atrial pressure (RAP) is crucial in cardiogenic shock, yet echocardiographic surrogates are often unreliable. In this exploratory analysis of 43 patients with ischaemic cardiogenic shock, pulmonary artery catheter–derived RAP was compared with right heart echocardiographic indices. Only right ventricular e’ velocity demonstrated a weak correlation with RAP ( rho = 0.31, p = 0.04), but did not significantly discriminate elevated pressure. Other Doppler and morphometric measures showed no meaningful associations. Echocardiographic parameters correlated poorly with invasive RAP, indicating that conventional indices cannot reliably substitute for pulmonary artery catheterisation in assessing venous congestion in this population.

Lashin et al. (2026) conducted an observational in ischaemic cardiogenic shock (n=43). Right heart echocardiographic indices vs. Pulmonary artery catheter-derived right atrial pressure was evaluated on Correlation with pulmonary artery catheter-derived right atrial pressure (rho = 0.31, p=0.04). Right ventricular e' velocity demonstrated only a weak correlation with pulmonary artery catheter-derived right atrial pressure (rho = 0.31, p = 0.04) and did not discriminate elevated pressure.
