Prevalence of WRF by CRF stage. Prevalence of WRF increased along with the decrease of initial GFR at admission. Dark wine color represents persistent WRF, and gray color represents transient WRF. Both transient and persistent WRF increased as GFR grade decreased, in the (A) total study population, (B) HFrEF group, and (C) HFpEF group. GFR indiactes glomerular filtration rate; HFpEF, heart failure with preserved ejection fraction; HFrEF, heart failure with reduced ejection fraction; WRF, worsening renal function.
