Treatment Intensity for the Management of Cardiogenic Shock: Comparison Between STEMI and Non-STEMI

Cardiogenic shock is a leading cause of mortality in patients with acute myocardial infarction. The authors sought to compare clinical characteristics, hospital trajectory, and drug and device use between patients with ST-segment elevation myocardial infarction-related cardiogenic shock (STEMI-CS) and those without (non-ST-segment elevation myocardial infarction complicated by cardiogenic shock [NSTEMI-CS]). We analyzed data from 1,110 adult admissions with cardiogenic shock complicating acute myocardial infarction (AMI-CS) across 17 centers within Cardiogenic Shock Working Group. The primary end point was in-hospital mortality. Our study included 1,110 patients with AMI-CS, of which 731 (65.8%) had STEMI-CS and 379 (34.2%) had NSTEMI-CS. Most patients were male (STEMI-CS: 71.6%, NSTEMI-CS: 66.5%) and White (STEMI-CS: 53.8%, NSTEMI-CS: 64.1%). In-hospital mortality was 41% and was similar among patients with STEMI-CS and NSTEMI-CS (43% vs 39%, = 0.23). Patients with out-of-hospital cardiac arrest had higher in-hospital mortality in patients with NSTEMI-CS (63% vs 36%, = 0.006) as compared to patients with STEMI-CS (52% vs 41%, = 0.16). Similar results were observed for in-hospital cardiac arrest in patients with STEMI-CS (63% vs 33%,
