Tissue Doppler imaging as a long-term prognostic index in left ventricular systolic dysfunction.

Background: Tissue Doppler parameters correlate with left ventricular (LV) filling pressure and can be useful as prognostic indexes for patients with heart failure.

Objective: Determine whether tissue Doppler parameters can predict events during long term follow-up of outpatients with LV systolic dysfunction.

Methods: Retrospective study with 73 patients (aged 60.
