Purpose
Impaired contractile function after a heart attack of the heart is a major cause of "heart failure" limiting quality of life and prognosis, which cannot be prevented even with optimal standard therapy, including immediate balloon/stent dilation of the infarct vessel.
The aim of the REPAIR-AMI trial is to investigate whether infusion of progenitor cells into the infarct vessel (after successful reperfusion therapy) may improve left ventricular contractile function compared to placebo therapy. After bone marrow aspiration progenitor cells are enriched via a centrifugation method.

Detailed Description:
- The study is a double-blind, placebo-controlled, randomized, multicenter trial.
- Patients after an acute myocardial infarction, undergoing successful reperfusion therapy are included.
- All patients undergo bone marrow aspiration 3 to 6 days after the infarction.
- After cell processing, enriched bone marrow-derived progenitor cells or placebo medium is infused direct into the infarct related artery during stop-flow. In addition, a left ventricular angiography is performed.
- After 4 months left ventricular angiography is repeated. The primary endpoint is the difference in change of left ventricular ejection fraction between the two groups.
