Cardiac arrest & resuscitation
Impact of cardiac arrest in patients with cardiogenic shock due to ST-elevation myocardial infarction
Authors' conclusion
In STEMI-related CS, concomitant OHCA or IHCA is associated with distinct clinical profiles, coronary anatomy, intensity of treatment and markedly impaired long-term survival.
Study context
- Population
- Consecutive patients with cardiogenic shock (CS) and ST-elevation myocardial infarction (STEMI) undergoing immediate coronary angiography and percutaneous coronary intervention (PCI), two tertiary university hospitals, 2016–2025
- Participants
- 345 patients
- Exposure
- STEMI-CS with OHCA or in-hospital cardiac arrest (IHCA) vs without cardiac arrest
- STEMI-CS-no CAn = 150reference
- STEMI-CS-OHCAn = 120
- STEMI-CS-IHCAn = 75
- Outcome
- All-cause mortality
- Follow-up
- 1 year

Main finding
As reported in the abstract
STEMI-CS-OHCA vs STEMI-CS-no CA: P = 0.004 · STEMI-CS-IHCA vs STEMI-CS-no CA: P < 0.001 · STEMI-CS-IHCA vs STEMI-CS-OHCA: P = 0.555
Observational data: associations, not effects.

— not stated in the abstract
- SYNTAX score: p < 0.001
Clinical characteristics
- STEMI-CS-IHCA older vs STEMI-CS-OHCA; lower arterial pressure, LVEF, eGFR and higher arterial lactate vs STEMI-CS-no CA and STEMI-CS-OHCA
