Stress Echocardiography to Detect Exercise Pulmonary Hypertension in Patients With Chronic Thromboembolic Pulmonary Disease.

ABSTRACT:

Background

This study was aimed at determining whether stress echocardiography could detect exercise pulmonary hypertension (ePH) in patients with mild chronic thromboembolic pulmonary disease (CTEPD) as compared with right-heart catheterization (RHC).

Methods

Thirty-six symptomatic patients with persistent residual perfusion defects detected using ventilation/perfusion scintigraphy underwent a haemodynamic assessment by RHC and echocardiography at rest and during exercise. We compared pulmonary pressures in echocardiography with RHC values using the definitions in current ESC/ERS guidelines for ePH [mean pulmonary artery pressure/cardiac output (mPAP/CO) slope > 3 mmHg/L/min] and PH (mPAP > 20 mmHg).

Results

Ten of the 36 patients (28%) exhibited an increase in the i
