Figure 3. Survival rates according to renal dysfunction Figure 3. Survival rates according to renal dysfunction. Kaplan-Meier curves of the 12-month survival rates according to renal dysfunction in all (A), HFpEF (B), and HFrEF (C) patients are presented. GFR = glomerular filtration rate; HFpEF = heart failure with preserved ejection fraction; HFrEF = heart failure with reduced ejection fraction. Figure 3.
