Figure 1 There is significant discordance in the normal values of left ventricular ejection fraction reported by several major scientific societies and associations.
This makes the classification of heart failure based on the left ventricular ejection fraction problematic.

Figure 2 Left ventricular ejection fraction adjusted hazard ratios in patients with heart failure (number of echocardiograms = 40616).
Left ventricular ejection fraction (LVEF) intervals are inclusive of the lower threshold. Error bars represent the 95%CI. The referent group was outpatients with an LVEF of 60%-65%. While 51192 echocardiograms were performed on patients with heart failure in the primary analysis, only 40616 echocardiograms are represented in this figure due to excluding echocardiograms missing measurements of end-diastolic volume index or wall thicknesses, for which adjustments were made in the analysis.

Figure 3 Incident rate of cardiovascular-related mortality.
The rate of cardiovascular (CV)-related mortality per 1000 person-years is presented separately for women (top graph) and men (bottom) according to 5-unit increments in the left ventricular ejection fraction. The total number of deaths contributing to the rate of mortality in each group (red numerals) is provided above the horizontal axis. IQR: Interquartile range.
