Acute cardiac care & resuscitation
Impact of annual volume of cases and intensive cardiac care unit availability on mortality of patients with acute myocardial infarction-related cardiogenic shock treated at revascularization capable centres
Authors' conclusion
Most CS-STEMI patients were attended at psRCC with high volume of cases and ICCU available. The combination of high volume and ICCU availability showed the lowest mortality.
Study context
- Population
- Consecutive patients with cardiogenic shock (CS) and ST elevation myocardial infarction (STEMI) discharged from Spanish National Healthcare System percutaneous and surgical revascularization capable centres, 2016–20CS-STEMI episodes, 44 hospitals
- Participants
- 3,074 CS-STEMI episodes
- Exposure
- Hospital volume of CS cases, intensive cardiac care unit (ICCU) availability and heart transplantation (HT) programmes
- Outcome
- In-hospital mortality
Methodological detailsnationwide registry, multilevel logistic regression, propensity score matching
- Nationwide registry
- Multilevel logistic regression
- Propensity score matching
Main finding
As reported in the abstract
Odds ratio
0.87
High volume of cases · adjusted model; trend to an association with lower mortality
Odds ratio
0.88
ICCU · adjusted model; trend to an association with lower mortality
Odds ratio

P = 0.007
High-volume hospitals with ICCU · after propensity score matching
- Treatment at HT centres not associated with lower mortality
- P = 0.121
