Effectiveness of Sacubitril/Valsartan in Real-World Settings, With Stephen Greene, MD


Analysis of the GWTG-HF registry demonstrates the efficacy of sacubitril/valsartan in real-world settings. Study investigator Stephen Greene, MD, offers further perspective on the topic in an interview.

A new analysis of real-world data from patients hospitalized for heart failure with reduced ejection fraction (HFrEF) is underlining the benefits of prescribing the sacubitril/valsartan (Entresto) prior to hospital discharge in this patient population.

An analysis of Medicare beneficiaries aged 65 years and older from the Get with the Guidelines-Heart Failure (GWTG-HF) registry, results suggest use of sacubitril/valsartan was associated with a significantly lower risk of mortality and hospitalization compared to those not prescribed the agent, but investigators pointed out less than 11% of patients received a prescription during the study period.

Despite demonstrating an efficacy and safety profile worthy of FDA approval for HFrEF in 2015 and inclusion in recent guidelines, prescribing rates of sacubitril/valsartan remain subpar. Some point to skepticism surrounding effects in real-world vs. clinical trial settings as a factor hindering optimal prescription. With this in mind, investigators designed the current study to provide insight into the real-world use and benefits of sacubitril/valsartan.

Using the GWTG-HF registry, investigators identified 14,320 patients hospitalized for HFrEF from October 2015-December 2018 for inclusion. Inclusion criteria for the study included being aged 65 years or older, being discharged alive, having complete medical history, and having no contraindications to sacubitril/valsartan. Investigators noted October 2015 was chosen as the start date to allow a 3-month transition period after the FDA’s July 2015 approval of sacubitril/valsartan.

Of the 14,320 patients identified for inclusion, 1151 (10.9%) were prescribed sacubitril/valsartan at discharge. Of the 12,679 not prescribed sacubitril/valsartan at discharge, 7857 (62.0%) were prescribed an ACE inhibitor or ARB at discharge. Investigators pointed out prescribing rates for sacubitril/valsartan appeared to increase over time.

In analyses with inverse probability of treatment weighting and adjustment for other HFrEF medications, use of sacubitril/valsartan was independently associated with lower all‐cause mortality (aHR, 0.82; 95% CI, 0.72–0.94; P=.004), but not all‐cause hospitalization (aHR, 0.97; 95% CI, 0.89–1.07; P=.55) or heart failure hospitalization (aHR, 1.04; 95% CI, 0.91–1.18; P=.59) compared to use of ACEs/ARBs at 12 months. In analyses comparing use of sacubitril/valsartan vs. nonuse, results indicated patients receiving sacubitril/valsartan had a lower risk of all‐cause mortality (aHR, 0.69; 95% CI, 0.60–0.79; P <.001) and all‐cause hospitalization (aHR, 0.90; 95% CI, 0.82–0.98; P=.02), but not heart failure hospitalization (aHR, 0.94; 95% CI, 0.82–1.08; P=.40).

Investigators also pointed out sacubitril/valsartan had the lowest unadjusted incidences of 30-day and 12-month mortality compared to those receiving an ACE/ARB or neither therapy. Additionally, those receiving neither had the highest incidences of mortality at 30 days and 12 months.
