Acute cardiac care & resuscitationCohort study
Impact of cardiac arrest in patients with cardiogenic shock due to ST-elevation myocardial infarction
- retrospective study
- consecutive patients
- two tertiary university hospitals
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
- Patients with cardiogenic shock (CS) and ST-elevation myocardial infarction (STEMI) undergoing immediate coronary angiography and percutaneous coronary intervention (PCI), admitted between 2016 and 2025STEMI-CS-no CA 150 · STEMI-CS-OHCA 120 · STEMI-CS-IHCA 75
- Participants
- 345 patients
- Exposure
- CS without cardiac arrest vs CS with OHCA vs CS with in-hospital cardiac arrest (IHCA)
- STEMI-CS-no CAn = 150
- STEMI-CS-OHCAn = 120
- STEMI-CS-IHCAn = 75
Main finding
As reported in the abstract
Initial shockable rhythm
Observational data: associations, not effects.
Further findings
All-cause mortality · 1-year
| Outcome | STEMI-CS-no CA | STEMI-CS-OHCA | STEMI-CS-IHCA |
|---|---|---|---|
| Time to return of spontaneous circulation | Not reported in the abstract | 19.6 min | 10.0 min |
| SYNTAX score | 18.6 | 21.5 | 27.2 |
- Time to return of spontaneous circulation: p < 0.001
- SYNTAX score: p < 0.001
- All-cause mortality: STEMI-CS-OHCA p = 0.004
- All-cause mortality: STEMI-CS-IHCA p < 0.001
- All-cause mortality: no significant difference between cardiac arrest subgroups (p = 0.555)
Baseline characteristics of STEMI-CS-IHCA
- STEMI-CS-IHCA patients were older
- Lower arterial pressure, left ventricular ejection fraction, estimated glomerular filtration rate and higher arterial lactate in STEMI-CS-IHCA compared to STEMI-CS-no CA and STEMI-CS-OHCA
