Authors' conclusion

STEMI and NSTEMI patients with CS have distinct clinical profiles and management strategies across all hospital levels. Although they experience similar rates of short and long-term mortality, associations between mechanical circulatory support use and outcomes differ by phenotype. These findings suggest that AMI type should inform management strategies and research design in CS.

Study context

Population
Adults treated for cardiogenic shock due to STEMI or NSTEMI, 2016 to 2022patients identified
Participants
1,375 adults
Exposure
Cardiogenic shock (CS) due to acute myocardial infarction (AMI) with and without ST-segment elevation
  • STEMI-CSn = 57%
  • Non-STEMI-CS (NSTEMI-CS)n = 43%
Outcome
All-cause mortality
Follow-up
6-month

Main finding

As reported in the abstract

P = 0.53

Observational data: associations, not effects.

Secondary outcomes

Management in those undergoing left heart catheterization

Coronary artery bypass grafting

Percutaneous coronary intervention

In-hospital all-cause mortality

Similar in both groups

Management in those undergoing left heart catheterization

Management patterns were consistent across hospital levels

Associations with 6-month mortality (multivariable analysis)

Revascularization associated with lower 6-month mortality in both groups
Intra-aortic balloon pump or percutaneous ventricular assist device use associated with lower mortality only in STEMI-CS
Venoarterial extracorporeal membrane oxygenation associated with increased mortality in both AMI types
