Abstract

AIMS: We investigated long-term mortality associated with changes in left ventricular ejection fraction (LVEF) in a large, real-world patient cohort. METHODS AND RESULTS: A total of 117 275 adults (63 ± 16 years, 46% women) had LVEF quantified by the same method ≥6 months apart. This included 17 343 cases (66 ± 15 years, 48% women) being initially investigated for heart failure (HF). During 3.3 [interquartile range (IQR) 1.7-6.0] years from first to last echocardiogram, median change in LVEF was -1 (IQR -8 to +5) units from a baseline of 62% (IQR 54-69%). During subsequent 7.6 (IQR 4.3-10.1) years of follow-up, 11 397 (9.7%) and 34 101 (29.1%) cases died from cardiovascular disease and all c..
