A Real-world Study of Clinical Treatment Guidelines for Patients With Heart Failure With Reduced Ejection Fraction Treated With Sacubitril/Valsartan (REACT-HFrEF-RO)

July 1, 2026 updated by: Novartis Pharmaceuticals

Real-world Adoption of Clinical Treatment Guidelines for Patients With Heart Failure With Reduced Ejection Fraction in Treatment With Entresto in Romania (REACT-HFrEF-RO)

The aim of this study was to describe the real-world clinical profile, treatment patterns, and guideline alignment of patients with heart failure with reduced ejection fraction (HFrEF) treated with sacubitril/valsartan in routine clinical practice in Romania. The study used secondary use of data, with all analyses conducted on anonymized, pre-existing data collected for routine clinical and administrative purposes.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Patients Receiving all Four Guideline-recommended Therapeutic Classes for HFrEF
Time Frame: Up to approximately 5 years and 6 months
The four guideline-recommended therapeutic classes include sacubitril/valsartan, beta-blockers, mineralocorticoid receptor antagonists, and sodium-glucose cotransporter-2 (SGLT2) inhibitors.
Up to approximately 5 years and 6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Patients by Demographic Category
Time Frame: Up to approximately 5 years and 6 months
Demographics include age group and sex.
