SmartHF is a 12-week clinical study designed to help people with a type of heart failure called HFrEF (Heart failure with reduced ejection fraction). People with HFrEF have a heart that does not pump blood as well as it should. This study uses a special web application to optimize, or improve, their medications. The tool looks at health records and suggests better medicine plans in a way that’s easy to understand. Participants will either use this web app or not, and researchers will compare the results.

Participants must be at least 18 years old and have internet access. They should have a heart pumping strength (ejection fraction) of 40% or less. People with advanced heart failure, certain cancers, or pregnant women cannot join.

• The study lasts for 12 weeks with follow-up after a clinic visit.
• Eligible participants will be randomly assigned to use the app or not.
• Participants need to have access to the internet and their health portal.

This study aims to see if this app helps doctors prescribe the best medicines for heart failure patients.
