Acute cardiac care & resuscitationSecondary analysis
Availability of mechanical circulatory support (MCS) and hospital survival in ST-segment elevation myocardial infarction related cardiogenic shock (STEMI-CS)
- Secondary analysis of the prospective 'Feedback Intervention and Treatment Times in ST-segment Elevation Myocardial Infarction' (FITT-STEMI) registry
Authors' conclusion
In this large registry of patients with STEMI-CS, hospital survival did not differ between centres with and without MCS availability.
Study context
- Population
- Patients with STEMI-CS at hospital admission, 2013–2022patients with STEMI-CS at hospital admission · MCS centres 4,340 · non-MCS centres 1,264
- Participants
- 5,604 patients
- Comparison
- Outcome in STEMI-CS treated in MCS and non-MCS centres
- MCS centresn = 4,340
- non-MCS centresn = 1,264reference
- Primary endpoint
- Hospital mortality
