The prognostic value of pulmonary artery compliance in cardiogenic shock.

ABSTRACT: The aim of this study was to evaluate the pathophysiological role and the prognostic significance of pulmonary artery compliance (CPA), a measure of right ventricular pulsatile afterload, in cardiogenic shock. We retrospectively included 91 consecutive patients with cardiogenic shock due to primary left ventricular failure, monitored with a pulmonary artery catheter within the first 24 h. CPA was calculated as the ratio of stroke volume to pulmonary artery pulse pressure, and we determined whether CPA predicted mortality and whether it performed better than other pulmonary hemodynamic variables. The overall in-hospital mortality in our cohort was 27%. Survivors and nonsurvivors had comparable left ventricular ejection fraction, systolic, diastolic and mean pulmonary artery pressure, transp
