Heart failure & cardiomyopathiesCohort study
Worse long-term outcomes in new-onset HF with preserved EF (HFpEF) vs HFrEF and HFmrEF: findings from the Stockholm PREFERS study
- Stockholm PREFERS study
- prospective
Authors' conclusion
In new-onset HF managed in university hospital-based HF clinics, HFpEF had worse long-term outcomes than HFmrEF and HFrEF combined. The findings highlight the severity of HFpEF and the need for more effective treatment strategies.
Study context
- Population
- Patients with new-onset heart failure treated in heart failure (HF) clinics, by ejection fraction categoryenrolled between 2015 and 2019 · HFpEF 135 · HFmrEF 61 · HFrEF 351

- HFrEFn = 351
- Outcome
- Time to cardiovascular (CV) mortality or first HF hospitalization (HFH)
- Follow-up
- Median 3.8 years (IQR 3.0-4.7)
