Abstract

Background: Current guidelines do not recommend periodically repeating echocardiograms in the follow-up of stable heart failure patients with reduced ejection fraction (HFrEF). The objective of the study was to verify the additional prognostic information provided by a comprehensive re-assessment of their cardiac function and hemodynamic profile at Doppler echocardiography in HFrEF patients. Methods: Retrospective analysis of 769 stable HFrEF outpatients who underwent two complete echocardiograms, at baseline and at re-assessment. Main candidate predictors of prognosis were: left ventricular (LV) filling pattern, pulmonary artery systolic pressure (PASP) and right ventricular function (TAPSE). Age, LV ejection fraction, mitral regurgitation severity, NYHA class, brain natriuretic peptide plasma levels at baseline, and their changes at 12 months, were used as covariates. Median follow-up was 30 months. All-cause death was the study end-point. Results: At baseline, restrictive filling pattern and low TAPSE were significant predictors of poor prognosis. At re-evaluation, persistently restrictive/worsened filling pattern, persistently-low/worsened TAPSE and worsened PASP, were associated with poorer survival. A significant interaction between changes in TAPSE, PASP and LV filling pattern was observed: in the restrictive pattern subgroup, survival was poorer in worsened/persistently low TAPSE (p < 0.01); in non-restrictive pattern subgroup, survival was poorer in worsened/persistently elevated PASP (p = 0.01). The re-assessment model improved the C-index from 0.69 to 0.74 (P < 0.01) compared to baseline model. Conclusions: Doppler echocardiographic re-assessment of LV filling pattern, PASP and TAPSE allows a better prognostic stratification of HFrEF outpatients than baseline evaluation and is additional to changes in BNP and NYHA class.
