Prognostic Role of Pulmonary Impedance Estimation to Predict Right Ventricular Dysfunction in Pulmonary Hypertension

Abstract

Raised pulmonary Zc was independent of elevated mPAP in patients with PH and more strongly predictive of maladaptive RV remodelling than PVR and mPAP. Use of this straightforward method to determine pulmonary Zc may help to better characterize pulsatile components of RV afterload in patients with PH than mPAP or PVR alone.
