This analysis aims to investigate whether the availability of mechanical circulatory support (MCS) improves hospital survival rates in patients with ST-elevation myocardial infarction-related cardiogenic shock (STEMI-CS).
Secondary analysis of the FITT-STEMI registry comparing outcomes in STEMI-CS patients treated at MCS centers and non-MCS centers.
Included 5604 patients with STEMI-CS admitted from 2013 to 2022, focusing on hospital mortality as the primary endpoint.
Used propensity score matching for outcome comparison after adjusting for confounding factors.
Hospital mortality was 44.7% in MCS centers versus 45.0% in non-MCS centers (OR 0.985, 95% CI 0.869-1.118, p = 0.820).
Even after adjustments and stratification, the results remained consistent, indicating no significant difference.
Post-propensity score matching, mortality was 45.8% in MCS centers and 43.7% in non-MCS centers (OR 1.070, 95% CI 0.888-1.288, p = 0.478).
