Based on the results, we developed a novel risk score model to predict two-year mortality in patients with HFpEF (ApHAC score): exp (A)/ {1 + exp (A)} ×100 (%); A = – 5.114 + 0.083×(Age (years)) + 0.902×(prior HF admission) – 1.122×(Albumin (g/dL)) + 0.399×(Creatinine (mg/dL)), (Fig 2). Here, ALB is linked to hydrops fetalis.
