Comparative outcomes of culprit-only versus complete revascularisation in cardiogenic shock complicating acute myocardial infarction: insights from the Gulf-Cardiogenic Shock registry

No statistically significant differences in hospital mortality or long-term MACCE-free survival were observed between culprit-only PCI and multivessel PCI strategies in patients with cardiogenic shock complicating acute myocardial infarction. However, patients older than 70 years may benefit from a multivessel PCI approach. These findings support current guideline recommendations favouring culprit-only PCI due to reduced procedural complexity while highlighting the need for individualised treatment strategies based on patient age and clinical factors. Further prospective randomised studies are needed to validate these age-specific findings and identify optimal patient selection criteria for each revascularisation strategy.
