Heart failure & cardiomyopathies
Long-Term Follow-Up of the TRED-HF Trial: Implications for Therapy in Patients with Dilated Cardiomyopathy and Heart Failure Remission
Authors' conclusion
The risk of relapse in the 5 years following the TRED-HF trial remained high.
Study context
- Population
- Patients with recovered dilated cardiomyopathy (DCM) after HF therapy withdrawal in TRED-HF

- Primary endpoint
- Relapse: ≥10% reduction in LVEF to <50%, doubling of NT-proBNP to >400 ng/L, or clinical features of HF
Methodological detailsnon-randomised reporting of outcomes, Patients randomised to continue therapy withdrew treatment between 6 and 12 months; restart of therapy recommended post-trial; follow-up until May 2023
