Coronary disease & ACSCohort study
Declining Risk of Heart Failure Hospitalization Following First Acute Myocardial Infarction in Scotland Between 1991–2016
- Retrospective cohort study
- population-based
- nationwide
Authors' conclusion
The incidence of HFH following AMI in Scotland has decreased since 1991.
Study context
- Population
- Patients in Scotland discharged alive after a first acute myocardial infarction (AMI) between 1991 and 2015, no prior heart failure (HF)
- Participants
- 175,672 patients
- Exposure
- Trends in HF hospitalization after first AMI, 1991 vs 2015
- Outcome
- Incidence of first HF hospitalization (per 1000 person-years)
- Follow-up
- 1 year after discharge
Main finding
As reported in the abstract
HFH incidence at 1 year after discharge (per 1000 person-years)
- Adjusted risk of HF hospitalization (HFH) at 1 year after discharge decreased
- 53% (accounting for competing risk of death; 95% CI 45-60%)
Observational data: associations, not effects.
Further findings
First HF hospitalization, whole cohort · median follow-up 6.7 years
- Patients with a first HF hospitalization
- 21 445 (12.2%)
Adjusted risk of HF hospitalization at 5 and 10 years
- Similar decreases at 5 and 10 years
