Improved Prognostic Performance of Cardiac Power Output With Right Atrial Pressure: A Subanalysis of the ESCAPE Trial

The initial derivation of cardiac power output (CPO) included the difference between mean arterial pressure (MAP) and right atrial pressure (RAP) in the numerator, before multiplying by cardiac output (CO). We hypothesized that the inclusion of RAP (CPO-RAP) would enhance the prognostic performance of this parameter in those with an elevated RAP.We obtained patient-level data from the ESCAPE trial via the Biolincc database. Participants with...
