Table 3 Classification of heart failure based on time-dependent changes in LVEF
Changes in phenotype | Definition |
|---|---|
Heart failure with recovered EF: HFrecEF | LVEF improved during the treatment course and the condition transitioned from HFrEF to HFmrEF or HFpEF, or from HFmrEF to HFpEF The outcome is relatively favorable |
Heart failure with worsened EF: HFworEF | LVEF decreased with the treatment course and the condition transitioned from HFpEF to HFmrEF or HFrEF, or from HFmrEF to HFrEF The outcome is poor |
Heart failure with unchanged EF: HFuncEF | No major change is observed in LVEF throughout the course |
