Variation in Renal Function Following Transition to Sacubitril/Valsartan in Patients With Heart Failure
Bibliographic record
Abstract
Some patients with heart failure may experience transient changes in kidney function upon transition to sacubitril/valsartan. Whether such changes portend adverse outcomes or influence long-term treatment benefits with sacubitril/valsartan continuation is unknown. This investigation aimed to evaluate the association between the occurrence of moderate estimated glomerular filtration rate (eGFR) decline (>15%) after initial exposure to sacubitril/valsartan and subsequent cardiovascular outcomes and its treatment benefits in PARADIGM-HF and PARAGON-HF. In sequential run-in phases, patients were titrated to enalapril 10 mg twice daily and then sacubitril/valsartan 97 mg/103 mg twice daily (in PARADIGM-HF) or valsartan 80 mg twice daily and then sacubitril/valsartan 49 mg/51 mg twice daily (in PARAGON-HF). Among randomized participants, 11% in PARADIGM-HF and 10% in PARAGON-HF experienced eGFR decline (>15%) during sacubitril/valsartan run-in. eGFR partially recovered (from nadir to postrandomization week 16) regardless of sacubitril/valsartan continuation or switch to renin-angiotensin system inhibitor (RASi) postrandomization. Initial eGFR decline was not consistently associated with clinical outcomes in either trial. Treatment benefits of sacubitril/valsartan vs RASi on primary outcomes were similar irrespective of run-in eGFR decline in PARADIGM-HF (eGFR decline, HR: 0.69; 95% CI: 0.53-0.90; and no eGFR decline, HR: 0.80; 95% CI: 0.73-0.88; Pinteraction = 0.32) and PARAGON-HF (eGFR decline, rate ratio [RR]: 0.84; 95% CI: 0.52-1.36 and no eGFR decline, RR: 0.87; 95% CI: 0.75-1.02, Pinteraction = 0.92). The treatment effect of sacubitril/valsartan remained consistent across a range of eGFR declines. Moderate eGFR decline when transitioning from RASi to sacubitril/valsartan is not consistently associated with adverse outcomes, and its long-term benefits are retained in heart failure across a broad range of eGFR declines. Early eGFR changes should not deter continuation of sacubitril/valsartan or stall uptitration.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
