Chronic Heart Failure With Reduced Ejection Fraction (HFrEF)

The purpose of the BRIDGE study is to learn whether supplementing traditional center-based cardiac rehabilitation (CBCR) with a mobile health technology intervention can help patients monitor their health, stay engaged in healthy lifestyle behaviors, better manage cardiovascular risk factors, and improve overall health outcomes. Cardiac rehabilitation is an evidence-based outpatient program designed to help people recover from heart-related conditions through supervised exercise, education, counseling, and support for healthy lifestyle changes. Although cardiac rehabilitation is highly recommended and beneficial, many patients do not receive the full benefits of the program. Some patients attend fewer sessions than recommended, and many find it difficult to maintain healthy habits outside of the clinic, such as regular physical activity, heart-healthy eating, taking medications as prescribed, monitoring blood pressure, and managing weight. This study will test whether combining CBCR with mobile health tools may improve participation and support healthy behaviors at home. Mobile health tools include mobile phone applications, connected devices such as a weight scale, blood pressure monitor, and activity tracker, as well as personalized text messages designed to encourage and support healthy self-care. This study will help determine whether these mobile health tools can make cardiac rehabilitation more effective and help patients maintain healthy behaviors beyond the clinic setting.
