Title: A Double-blind, Randomised, Controlled Study of Autologous Bone Marrow-Derived Stem Cell Transfer In Patients With ST-Segment Elevation Myocardial Infarction.
Brief Summary: The benefit of reperfusion therapies for ST-elevation acute myocardial infarction (STEMI) is limited by postinfarction left ventricular (LV) dysfunction.The purpose of this study is to determine whether intracoronary transfer of bone marrow cells will augment left ventricular function recovery of the heart.


Options:
A: Inclusion Criteria:

* patients with acute myocardial infarction with cumulative ST-segment elevation \>=6mm, successful epicardial reperfusion after PCI and significant LV dysfunction

Exclusion Criteria:

* patients presenting within 2 hours of symptom onset (no dilution of any treatment effect from aborted infarctions)
* patients with prior coronary artery bypass grafting, pulmonary edema, cardiogenic shock or significant co-morbidities
B: Inclusion Criteria:

* Visual LVEF at angiogram or echocardiography ≤45%
* Treatment by primary PCI within 24 hours of the onset of chest pain or initial treatment with thrombolysis within the 12 hours followed by PCI within the 24 hours of the onset of chest pain
* Significant regional LV wall motion dysfunction in the infarct related territory
* Age \>18 years

Exclusion Criteria:

* Abnormal regional wall motion outside the infarct region
* Known previous myocardial infarction in the same target vessel
* Known pre-existing left ventricular dysfunction (EF\<45% prior to admission)
* Need for revascularization in the non infarct-related coronary within 4 months
* Pre-existing symptoms of heart failure or known cardiomyopathy
* Known active infection or chronic infection with HIV, HBV or HCV
* Chronic inflammatory disease
* Serious concomitant disease with a life expectancy of less than one year
* Follow up impossible (no fixed abode, etc)
* Contraindication for cardiac MRI (i.e. pace maker, neurostimulator, claustrophobia)
* Severe renal failure (creatinine \>250 mmol/l)
* Relevant liver disease (GOT \> 2x norm or spontaneous INR \> 1,5)
* Anemia (Hb \< 8.5 mg/dl), Thrombocytopenia (\<100.000/µl)
* Pregnancy
* Participation at a clinical trial in the last 30 days
C: Inclusion Criteria:

* patient included in one of the registered cell-based cardiac therapy of the participating center

Exclusion Criteria:

* none
D: Inclusion Criteria:

* acute myocardial infarction with time to revascularization \>6 hours from symptom start
* clear target vessel
* large myocardial infarction defined as: proximal vessel occlusion, CK \> 1000 U/L, myocardial scar in magnetic resonance imaging \> 10% of left ventricular muscle mass
* potential prior thrombolysis
* written informed consent

Exclusion Criteria:

* acute myocardial infarction with revascularization within 6 hours after symptom start
* prior myocardial infarction
* no clear target vessel
* contraindication for magnetic resonance imaging (e.g. pacemaker, ICD)
* severely depressed left ventricular ejection fraction (less than 20% in magnetic resonance imaging)
* prior hematologic disease
* prior chemo therapy
* prior stem cell transplantation
* prior treatment with G-CSF
* known alteration of the bone marrow by alcohol or drugs, e.g. agranulocytosis
* local infection of puncture sites
