Cohort study
Incident heart failure and recurrent coronary events following acute myocardial infarction
- Retrospective cohort study
- multicentre
- landmark analysis at 3 months post-discharge
Authors' conclusion
In a contemporary post-MI cohort, the risk for incident HF was greater than recurrent MI, even among those with normal EF and no HF at discharge.
Study context
- Population
- Patients with a primary discharge diagnosis of myocardial infarction (MI) at 28 Baylor Scott & White Health hospitals, January 2015 to December 2021landmark cohort N = 6210
- Participants
- 6,804 patients
- Outcome
- Incident HF, recurrent MI, all-cause death, all-cause and CV rehospitalizations
- Follow-up
- 1 year (landmark at 3 months post-discharge)
Main finding
As reported in the abstract
1-year outcomes (landmark cohort) · 1 year
- All-cause death
- 413 (6.7%)
- All-cause hospitalization
- 1730 (27.9%)
- CV hospitalization
- 735 (11.8%)
- Recurrent MI
- 234 (3.8%)
- Incident heart failure (HF) within 3 months of discharge (no history of HF)
- 1160 (23.8%)
- Incident HF with ejection fraction (EF) < 40%, 41-49%, >50%
- 42.2%, 26.7%, 31.1%
Observational data: associations, not effects.
Further findings
Death and hospitalizations in patients who developed HF
- Higher risk of death and hospitalizations with incident HF, irrespective of EF
- all P < .001
EF > 50% without prevalent HF or HF during index hospitalization (n = 2179) · 1 year
- Developed HF
- 257 (11.8%)
- Recurrent MI
- 77 (3.5%)
