Heart failure & cardiomyopathiesCohort study
Results of the Precision Event Monitoring for Patients With Heart Failure Using HeartLogic Study (PREEMPT-HF)
- Prospective observational study
- global
- single-arm
- patients and clinicians blinded to index and alerts
- 103 sites
Authors' conclusion
HeartLogic index trends were significantly different for patients who were readmitted for HF. These trends suggest that individuals at risk for readmission have had a more sustained worsening and/or insufficient intervention during the initial hospitalization for HF.

- Participants
- 2,155 participants · 103 sites
- Outcome
