Accuracy and Influencing factors of Pulmonary Artery Systolic Pressure estimated by Doppler Echocardiography: Comparsion with Right Heart Catheterization
Abstract:Purpose
This study aimed to explore the accuracy and influencing factors of noninvasive assessment of pulmonary artery systolic pressure by Doppler echocardiography (sPAPECHO) with right heart catheterization (RHC) as reference.
Methods
A total of 218 highly suspected pulmonary hypertension (PH) patients who underwent RHC and echocardiography within 7 days were included. The ratio of (sPAPECHO-sPAPRHC)/sPAPRHC was calculated and divided into three groups, namely, the underestimation group, accurate group and… Show more
