Estimation of Left Ventricular Filling Pressure with Exercise by Doppler Echocardiography in Patients with Normal Systolic Function: A Simultaneous Echocardiographic–Cardiac Catheterization Study

Doppler echocardiography is now used to evaluate left ventricular filling pressures in patients at rest. However, the clinical use of Doppler echocardiography in the determination of filling pressures with exercise has been less well studied.The aim of this prospective study was to confirm the validity of an accepted Doppler parameter (ratio of transmitral E velocity to Doppler tissue annular e' velocity [E/e']) as a measure of filling pressure...
