Longitudinal trajectories in renal function before and after heart failure hospitalization among patients with heart failure with preserved ejection fraction in the PARAGON-HF trial.

Worsening renal function may impact long-term outcomes in heart failure (HF). However, little is known about the longitudinal trajectories in renal function in relation to HF hospitalization or how this high-risk clinical event impacts renal outcomes. In PARAGON-HF, we evaluated the association between recency of prior HF hospitalization (occurring pre-randomization) and subsequent first renal composite outcome: (i) time to ≥50% decline in estimated glomerular filtration rate (eGFR); (ii) development of end-stage renal disease; or (iii) death attributable to renal causes. A total of 2306 (48.1%) patients had a history of prior HF hospitalization. Incident rates of the renal outcome were highest in those most recently hospitalized and decreased with longer time from last hospitalization. Treatment effect on the renal outcome of sacubitril/valsartan versus valsartan was similar between patients with (hazard ratio [HR] 0.43; 95% confidence interval [CI] 0.24-0.76) and without (HR 0.63; 95% CI: 0.33-1.18; p Heart failure hospitalization denotes increased risk for kidney disease progression which continues following recovery from HF decompensation in patients with HF with preserved ejection fraction.
