Systolic function recovery in Heart Failure: Frequency, prognostic impact and predictors

Area of Science:

• Cardiology
• Internal Medicine
• Clinical Research

Background:

• Systolic function recovery in Heart Failure (HF) with reduced ejection fraction (EF) is recognized but not fully understood.
• Characterizing recovery, its prognostic impact, and predictors is crucial for patient management.

Purpose of the Study:

• To characterize systolic function recovery in HF patients.
• To evaluate the prognostic impact of recovery on mortality.
• To identify predictors of systolic function recovery.

Main Methods:

• Analysis of 304 HF patients with two echocardiograms (2006-2015).
• Defined partial recovery (EF < 50%) and total recovery (EF ≥ 50%).
• Used multivariate logistic regression to identify recovery predictors and assess mortality risk.

Main Results:

• 49.3% showed no EF recovery, 18.1% partial, and 32.6% total recovery.
• Total recovery was associated with a 54% lower mortality risk.
• Predictors included female gender, non-ischemic etiology, and end-diastolic LV diameter < 60 mm.

Conclusions:

• HF patients who recover systolic function, particularly women with non-ischemic HF and smaller left ventricles, have a significantly better prognosis.
• Total systolic function recovery is linked to a substantial reduction in mortality risk.
