Abstract 11680: Impact of a Reduced Ejection Fraction on Short And Long-term Outcome in Patients With ST-elevation Myocardial Infarctions in Patients With and Without Cardiogenic Shock- Results From a German STEMI-registry

BackgroundDespite rapid percutaneous coronary interventions (PCI) impairment of left ventricular ejection fraction (LVEF) remains common in patients with acute ST-elevation myocardial infarctions (STEMI). There is few current data on prevalence of a reduced LVEF in STEMI-patients and its impact on prognosis. Aim of the present study was therefore to estimate this with data from a German STEMI-registry.MethodsAll STEMI-patients treated between 2006-18 at a large german PCI-Center and documented LVEF entered analysis. Patients were stratified by initial LVEFG1>50 %, G236-50%, G3≤35 % and separated in patients with and w/o concurrent cardiogenic shock (CS).ResultsOf 5001 patients analyzed 582 (12%) presented initially with CS, while 4419 (88%) did not. When stratifying the CS-cohort by LVEF, 120 (21%) could be attributed to G1, 276 (47%) to G2 and 186 (32%) to G3. In the cohort without CS 1812 patients(41%) could be attributed to G1, 2148 (49%) to G2 and 459 (10%) to G3. A reduced LVEF was associated with higher age in both patients with CS (G161±12 yrs., G263±13 yrs., G365±14 yrs., p=0.01) and without CS (G160±13 yrs., G265±13 yrs., G368±13yrs., p
