Effect of Pre-Hospital ARNI Therapy on Short-Term Outcomes in HFrEF

Evaluating the Impact of Pre-Hospital Angiotensin Receptor-Neprilysin Inhibitor (ARNI) Therapy on Short-Term Clinical Outcomes in Heart Failure Patients With Reduced Ejection Fraction: A Comparative Study

This study looks at people with heart failure who are admitted to the hospital. The goal of the study is to understand whether taking a heart failure medicine called angiotensin receptor-neprilysin inhibitor (ARNI) before hospital admission affects short-term health outcomes.

The study will compare two groups of participants: those who were already taking ARNI before coming to the hospital and those who were not. Information will be collected from medical records during the hospital stay, including heart-related events, kidney-related events, and how long participants stay in the hospital.

Some participants will also be followed for a short period after discharge. This study may help improve understanding of outcomes associated with ARNI use in people with heart failure in routine clinical care.
