A Cohort Study to Compare the Hospitalization Between Naive Sacubitril/Valsartan and Naive ACEi/ARBs Heart Failure Patients With Reduced Ejection Fraction Using Secondary US Electronic Health Records Data
- Registration Number
- NCT05096143
- Lead Sponsor
- Novartis Pharmaceuticals
- Brief Summary
A non-interventional retrospective cohort study conducted to compare the naive sacubitril/valsartan Heart Failure with reduced Ejection Fraction (HFrEF) patient population to a matched naive ACEi/ARB HFrEF patient population.
- Detailed Description
This was a non-interventional retrospective cohort study using the US secondary EHR dataset, Optum EHR, to compare the naive sacubitril/valsartan HFrEF patient population (aged ≥ 18 years) to a matched naive ACEi/ARB HFrEF patient population.
The study comprised of the following periods:
Identification period: 01-Jul-2015 to 31-Mar-2019
Study period
* 01-Jul-2014 to 31-Mar-2020 for primary objective and secondary objective 2 to 6.
* 01-Jul-2008 to 30-Sep-2020 for secondary objective 1.
Follow-up period: Patients were followed up until 31-Mar-2020, death or patient transfer out.
Baseline period: 365 days prior to index

Sacubitril/valsartan incident cohort Included patients
- Prescribed sacubitril/valsartan within the identification period (01-July-2015 to 31-Mar-2019), that had non-missing gender and year of birth data.
- With at least one ICD-9-CM or ICD-10-CM code for diagnosis of HF within one-year prior to date of first prescription of sacubitril/valsartan (index date), and are treated as part of the integrated delivery network.
- With first month active 365 days prior to index and last date active was greater than or equal to (≥) index, and the month of provider source data was greater than the final date of patient follow-up.
- That were ≥18 years old at index date.
- With a valid LVEF value ≤40%, prior to index (index date included).
Angiotensin-converting enzyme inhibitors (ACEi) and Angiotensin II receptor antagonist (ARB) incident cohort
Included patient:
- Prescribed ACEi or ARBs within the identification period (01-Jul-2015 to 31-Mar-2019), that had non-missing gender and year of birth data.
- With at least one ICD-9-CM or ICD-10-CM code for diagnosis of HF within one-year prior to date of first prescription of ACEi or ARB (index date), and were treated as part of the integrated delivery network.
- With first month active 365 days prior to index and last date active was ≥ index, and the month of provider source data is greater than the final date of patient follow-up.
- That were ≥ 18 years old at index date.
- With a valid LVEF value ≤ 40%, prior to index (index date included).
Sacubitril/valsartan incident cohort
Excluded patients for the primary objective and secondary objective 2 to 6:
- Patients who were prescribed sacubitril/valsartan within one-year prior to index date.
- Patients who were prescribed ACEi or ARBs, within one-year prior to index date (index date included).
Exclude patients for secondary objective 1:
- Patients who were prescribed sacubitril/valsartan prior to index date.
- Patients who were prescribed ACEi or ARBs prior to index date (index date included).
Angiotensin-converting enzyme inhibitors (ACEi) and Angiotensin II receptor antagonist (ARB) incident cohort
Exclude patients for the primary objective and secondary objective 2 to 6:
- Patients who were prescribed ACEi or ARBs within one-year prior to index date.
- Patients who were prescribed sacubitril/valsartan within one-year prior to index date (index date included).
- Which had a valid sacubitril/valsartan prescription that enables inclusion in the sacubitril/valsartan cohort.
- Exclude patients for secondary objective 1:
- Patients who were prescribed ACEi or ARBs prior to index date.
- Patients who were prescribed sacubitril/valsartan prior to index date (index date included).
- Which had a valid sacubitril/valsartan prescription that enables inclusion in the sacubitril/valsartan cohort
