AMI without Cardiogenic Shock
The DTU-STEMI pilot trial ((Door-To-Unload in STEMI Pilot Trial) - “Unloading the Left Ventricle Before Reperfusion in Patients With Anterior ST-Segment-Elevation Myocardial Infarction” - represents the first exploratory study testing whether LV unloading and delayed reperfusion in patients with STEMI without cardiogenic shock is safe and feasible.
Study Design: multicenter, prospective, randomized exploratory safety and feasibility trial, 50 patients (1:1 randomization) with anterior STEMI to LV unloading by using the Impella CP followed by immediate reperfusion (U-IR) versus delayed reperfusion after 30 minutes of unloading (U-DR).
Study Endpoints: The primary safety outcome was a composite of major adverse cardiovascular and cerebrovascular events at 30 days. Efficacy parameters included the assessment of infarct size by using cardiac magnetic resonance imaging.

AMI without Cardiogenic Shock
Study Design: multicenter, randomized, open-label trial
Study Results: Follow-up was completed for 591 of 600 patients (98.5%). Mortality was not different between the IABP and the control group (66.3% versus 67.0%; relative risk, 0.99; 95% CI, 0.88–1.11; P=0.98). There were also no differences in recurrent myocardial infarction, stroke, repeat revascularization, or rehospitalization for cardiac reasons (all P>0.05). Survivors’ quality of life as assessed by the EuroQol 5D questionnaire and the New York Heart Association class did not differ between groups.
