Acute cardiac care & resuscitationCohort study
Cardiogenic shock in the course of myocardial infarction: the results of the Shock-POL registry
- snapshot registry
- 9 cardiology centres across Poland
Authors' conclusion
Short-term mortality rate of AMI-related CS still amounts to 50%, which advocates in favour of further research evaluating the true role of MCS in this population.
Study context
- Population
- Patients with acute myocardial infarction (AMI)-related cardiogenic shock (CS) hospitalized between January and December 2023
- Participants
- 141 patients
- Outcome
- In-hospital mortality
Main finding
As reported in the abstract
In-hospital mortality rate
47.5% (n = 67)
Observational data: associations, not effects.
