Prognosis of cardiogenic shock secondary to culprit left main coronary artery lesion‐related myocardial infarction

Abstract Aims This study aimed to assess, in patients with cardiogenic shock secondary to unprotected left main coronary artery‐related myocardial infarction (ULMCA‐related AMICS), the incidence and predictors of no recovery of left ventricular function during the admission. Methods and results This was an observational study conducted at two tertiary care centres (2012–20). The main outcome measured was death or requirement for heart transplantation (HT) or left ventricular assist devices (LVAD) during the admission. A total of 70 patients were included. Percutaneous coronary intervention (PCI) was successful in 53/70 patients (75.7%). The combined endpoint of death or requirement of HT or LVAD during the admission occurred in 41/70 patients (58.6%). The highest incidence of the primary endpoint was observed among patients with profound shock and occluded left main coronary artery (LMCA) (20/23, 87%, P
