Temporal left ventricular ejection fraction variations and outcomes in wide population of cardiovascular patients with and without heart failure.

ABSTRACT:

Introduction

Heart failure (HF) with improved ejection fraction (HFimpEF) was shown to be related with improved outcome but increase of left ventricular ejection fraction (LVEF) in patients without HF is of less known clinical significance. The aim of the study was to evaluate long-term prognosis in patients with different cardiovascular disorders, with and without HF, depending on temporal variations of LVEF.

Methods

The study covered 31 920 patients (median age 71 years, 37.7% females) with different cardiovascular disorders and at least two measurements of LVEF separated by ≥1 month. Clinical parameters were acquired from database of Academic Repository of Clinical Cases of Medical University of Silesia. HFimpEF was defined by LVEF increase ≥10% in HF patients in relation
