Pulmonary perfusion and NYHA classification improve after cardiac resynchronization therapy.

ABSTRACT:

Background

Evaluation of cardiac resynchronization therapy (CRT) often includes New York Heart Association (NYHA) classification, and echocardiography. However, these measures have limitations. Perfusion gradients from ventilation/perfusion single-photon emission computed tomography (V/P SPECT) are related to left-heart filling pressures and have been validated against invasive right-heart catheterization. The aim was to assess if changes in perfusion gradients are associated with improvements in heart failure (HF) symptoms after CRT, and if they correlate with currently used diagnostic methods in the follow-up of patients with HF after receiving CRT.

Methods and results

Nineteen patients underwent V/P SPECT, echocardiography, NYHA classification, and the quality-of-life sco
