Pulmonary Hypertension Specific Therapy Improves Cardiac Structure and Function Without Detectable Changes in Doppler PA Systolic Pressure in Patients With Pulmonary Arterial Hypertension

Abstract

PURPOSE: Doppler-echocardiographic examination (DE) plays a central role in the diagnosis of pulmonary arterial hypertension (PAH). The role of the DE in the serial assessment of PAH is less well known. We sought to determine which 2-D and Doppler parameters are most influenced by PH specific therapy on serial DE examination.
