  • administrative data

Authors' conclusion

Despite having a HF diagnosis, 40% of patients do not see a cardiologist annually, regardless of disease severity. Simple stratification based on hospitalization history and diuretic use effectively predicts outcomes.

Study context

Population
All French patients reported as having heart failure (HF) in the previous 5 years and alive on 1 January 202080 years (70–87), 48% female
Participants
655,919 patients
Exposure
HF risk strata by prior HF hospitalisation and loop diuretic use; cardiology follow-up vs none
Outcome
All-cause mortality (ACM)
Follow-up
1 year
