Incidence and Predictors of Heart Failure with Reduced and Preserved Ejection Fraction After ST-Elevation Myocardial Infarction in the Contemporary Era of Early Percutaneous Coronary Intervention

Eur J Heart FailPublished

  • Cohort study
  • all-comer ST-elevation myocardial infarction (STEMI) patients
  • CardioLines Biobank

Authors' conclusion

In the current era of early STEMI reperfusion, still one in 10 patients develops heart failure, with approximately half of the patients with a reduced and half with a mildly reduced or normal LVEF. Predictors for the development of HFrEF were different from HFpEF.

Study context

Population
All-comer STEMI patients in the era of early PCI (CardioLines Biobank)
Participants
1,172 patients
Outcome
Incidence of post-STEMI HF, stratified by LVEF
Follow-up
Median 3.7 years (2.0, 5.5)

Main finding

As reported in the abstract

Post-STEMI HF incidence, by LVEF

Total incidence of post-STEMI HF

10.9%

Heart failure with reduced ejection fraction (HFrEF) (share of HF)

52.1%

HF with mildly reduced EF (share of HF)

29.4%

Heart failure with preserved ejection fraction (HFpEF) (share of HF)

18.5%

Observational data: associations, not effects.
