Acute cardiac care & resuscitationCohort study
External validation of organ perfusion pressure as a prognostic marker in cardiogenic shock
- retrospective analysis of a Multicenter International Registry
- consecutive patients
- external validation
Authors' conclusion
In this multicenter CS cohort, admission OPP was an independent prognostic marker of in-hospital mortality, irrespective of underlying CS etiology. Its inherent simplicity and demonstrated clinical robustness may support its integration into risk stratification and CS protocols.
Study context
- Population
- Patients admitted for cardiogenic shock related to heart failure or acute myocardial infarction, July 2023 to October 2024patients considered
- Participants
- 621 patients
- Exposure
- Admission organ perfusion pressure (OPP) as a predictor of in-hospital all-cause death
- nonsurvivorsn = 247
- Outcome
- In-hospital all-cause death
- Follow-up
- In-hospital
