Optimal Noninvasive Assessment of Left Ventricular Filling Pressures

Abstract

In intensive care unit patients, mitral E/Ea has a better correlation than BNP with PCWP. Both BNP and mitral E/Ea have high sensitivity for PCWP >15 mm Hg; however, E/Ea appears more specific in this patient population. In patients without cardiac disease, BNP appears more accurate than E/Ea for PCWP >15 mm Hg, whereas E/Ea appears more accurate in patients with cardiac disease.
