Acute cardiac care & resuscitationCohort study
Long-Term Outcomes of Cardiogenic Shock Complicating Myocardial Infarction
- Retrospective cohort study
- population-based
- linked health administrative databases
Authors' conclusion
Short- and long-term mortality among patients with AMI-CS is high, with minimal improvement over time. AMI-CS survivors experience significant morbidity, with high risks of readmission and death.
