Renal Outcomes in Patients with Systolic Heart Failure Treated With Sacubitril-Valsartan or Angiotensin Converting Enzyme Inhibitor/Angiotensin Receptor Blocker.

ABSTRACT:

Objective

To assess 4 adverse renal outcomes in a heterogeneous cohort of patients with systolic heart failure (HF) who were prescribed sacubitril-valsartan vs angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (ACEi/ARB).

Patients and methods

The OptumLabs Database Warehouse, which contains linked administrative claims and laboratory results, was used to identify patients with systolic HF who were prescribed sacubitril-valsartan or ACEi/ARB between July 1, 2015, and September 30, 2019. One-to-one propensity score matching and inverse probability of treatment weighting was used to balance baseline variables. Cox proportional hazards modeling was performed to compare renal outcomes in both medication groups, including 30% or more decline in estimated glomerular filtration rate (eGFR), doubling of serum creatinine, acute kidney injury (AKI), and kidney failure (eGFR < 15 mL/min per 1.73 m², kidney transplant, or dialysis initiation).

Results

A total of 4667 matched pairs receiving sacubitril-valsartan or ACEi/ARB were included; the mean follow-up period was 7.8±7.8 months. The mean age was 69.4±11 years; 35% were female, 19% black, and 15% Hispanic. The cumulative risk at 1 year was 6% for 30% or more decline in eGFR, 2% for doubling of serum creatinine, 3% for AKI, and 2% to 3% for kidney failure. Furthermore, no significant differences in risk were observed with sacubitril-valsartan compared with ACEi/ARB for a 30% or more decline in eGFR (hazard ratio [HR], 0.96; 95% CI, 0.79 to 1.10), doubling of serum creatinine (HR, 0.94; 95% CI, 0.69 to 1.27); AKI (HR, 0.80; 95% CI, 0.63 to 1.03), and kidney failure (HR 0.80; 95% CI, 0.59 to 1.08).

Conclusion

Among patients with systolic HF, the risk of adverse renal outcomes was similar between patients prescribed sacubitril-valsartan and those prescribed ACEi/ARB.

Project description:BackgroundGuidelines recommend targeting systolic blood pressure (SBP) <130 mm Hg in heart failure with preserved ejection fraction (HFpEF) with limited data.ObjectivesThis study sought to determine the optimal achieved SBP and whether the treatment effects of sacubitril/valsartan on outcomes are related to BP lowering, particularly among women who derive greater benefit from sacubitril/valsartan.MethodsUsing 4,795 trial participants, this study related baseline and time-updated mean achieved SBP quartiles (<120, 120 to 129, 130 to 139, ≥140 mm Hg) to the primary outcome (cardiovascular death and total heart failure hospitalization), its components, myocardial infarction or stroke, and a renal composite outcome. At the 16-week visit, the study assessed the relationship between SBP change and Kansas City Cardiomyopathy Questionnaire overall summary score (KCCQ-OSS) and N-terminal pro-B-type natriuretic peptide (NT-proBNP). The study analyzed whether the BP-lowering effects of sacubitril/valsartan accounted for its treatment effects.ResultsAverage age was 73 ± 8 years, and 52% of participants were women. After multivariable adjustment, baseline and mean achieved SBP of 120 to 129 mm Hg demonstrated the lowest risk for all outcomes. Sacubitril/valsartan reduced SBP by 5.2 mm Hg (95% confidence interval: 4.4 to 6.0) compared with valsartan at 4 weeks, which was not modified by baseline SBP. However, sacubitril/valsartan reduced SBP more in women (6.3 mm Hg) than men (4.0 mm Hg) (interaction p = 0.005). Change in SBP was directly associated with change in NT-proBNP (p < 0.001) but not KCCQ-OSS (p = 0.40). The association between sacubitril/valsartan and the primary outcome was not modified by baseline SBP (interaction p = 0.50) and was similar when adjusting for time-updated SBP, regardless of sex.ConclusionsBaseline and mean achieved SBP of 120 to 129 mm Hg identified the lowest risk patients with HFpEF. Baseline SBP did not modify the treatment effect of sacubitril/valsartan, and the BP-lowering effects of sacubitril/valsartan did not account for its effects on outcomes, regardless of sex.
