【 摘 要 】

Background: In patients with heart failure, chronic kidney disease is common and associated with a higher risk of renal events than in patients without chronic kidney disease. We assessed the renal effects of angiotensin/neprilysin inhibition in patients who have heart failure with preserved ejection fraction enrolled in the PARAGON-HF trial (Prospective Comparison of ARNI With ARB Global Outcomes in HF With Preserved Ejection Fraction). Methods: In this randomized, double-blind, event-driven trial, we assigned 4822 patients who had heart failure with preserved ejection fraction to receive sacubitril/valsartan (n=2419) or valsartan (n=2403). Herein, we present the results of the prespecified renal composite outcome (time to first occurrence of either: >= 50% reduction in estimated glomerular filtration rate (eGFR), end-stage renal disease, or death from renal causes), the individual components of this composite, and the influence of therapy on eGFR slope. Results: At randomization, eGFR was 63 +/- 19 mL.min(-1).1.73 m(-2). At study closure, the composite renal outcome occurred in 33 patients (1.4%) assigned to sacubitril/valsartan and 64 patients (2.7%) assigned to valsartan (hazard ratio, 0.50 [95% CI, 0.33-0.77];P=0.001). The treatment effect on the composite renal end point did not differ according to the baseline eGFR (<60 versus >= 60 mL.min(-1).1.73 m(-2) (P-interaction=0.92). The decline in eGFR was less for sacubitril/valsartan than for valsartan (-2.0 [95% CI, -2.2 to -1.9] versus -2.7 [95% CI, -2.8 to -2.5] mL.min(-1).1.73 m(-2) per year). Conclusions: In patients with heart failure with preserved ejection fraction, sacubitril/valsartan reduced the risk of renal events, and slowed decline in eGFR, in comparison with valsartan.
