CONSORT diagram of patient disposition. Measurements of left ventricular ejection fraction (LVEF) included all obtained historical data (not evaluated in the core lab) and the study baseline echo (evaluated in the core lab). Participants were included if there were at least two LVEF measurements of adequate quality, measured at least 1 year apart. They were classified as heart failure with recovered ejection fraction (HFrecEF) if at least one historical LVEF measured <35% and a subsequent or study baseline LVEF measured >35% and was at least 5% higher than the lowest previous LVEF. Participants were classified as persistent heart failure with reduced ejection fraction if any prior LVEF measured <35% and they did not experience improvement as previously mentioned and as heart failure with preserved ejection (heart failure with mid‐range ejection fraction) fraction if no prior or baseline LVEF measured <40%.
