- Early reperfusion for STEMI patients complicated by cardiogenic shock results in lower mortality compared to prolonged reperfusion.
- Shorter onset-to-balloon (OTB) and door-to-balloon (DTB) times are recommended to improve patient survival.
- A shorter OTB was associated with longer overall survival in patients vs prolonged OTB (43.3% and 55.5%, respectively).
- Mortality rates for short vs long DTB in this study were 44.9% and 55.8%, respectively.
The significant reduction of in-hospital mortality related to ST-segment elevation acute myocardial infarction (STEMI) has been greatly attributed to the overwhelming adoption of primary percutaneous intervention (PCI). STEMI patients with cardiogenic shock (CS) tend to experience a higher mortality even after PCI and the implantation of mechanical circulatory support (MCS) devices.A recent retrospective study published in European Heart Journal: Acute Cardiovascular Care
assessed the mortality benefit, if any, of reperfusion via primary PCI for patients with STEMI complicated with CS of 466 patients enrolled in the Coronary Revascularization Demonstrating Outcome Study in Kyoto (CREDO-Kyoto) acute myocardial infarction (AMI) registry.
