About

Impaired contractile function after a heart attack and due to coronary heart disease is a major cause of "heart failure" limiting quality of life and prognosis, which cannot be prevented even with optimal standard therapy.

The aim of the current trial is to investigate whether infusion of progenitor cells into the coronary artery supplying the most dyskinetic left ventricular area may improve left ventricular contractile function, compared to no cell infusion in the control group, in patients with old (>= 3 months) myocardial infarction.

Full description

The study is an open-label, controlled, randomized single-center trial.
Patients post myocardial infarction (>= 3 months) with a patent infarct-related artery are included.
Bone marrow-derived progenitor cells are aspirated under local anaesthesia, and after cell processing, are infused into the patent infarct-related artery during stop flow within the same day. Blood-derived progenitor cells are isolated out of 250ml peripheral venous blood, and after cell processing and 3 days culture, are infused into the patent infarct-related artery during stop flow. In addition, left ventricular angiography is performed. In the control group coronary angiography and left ventricular angiography without any intracoronary infusion are performed.
After 3 months, left ventricular angiography is repeated, and patients of the control group cross-over to active treatment with progenitor cells, whereas patients initially treated with progenitor cells cross-over to the alternate cell type.
The primary endpoint is the change in quantitative global left ventricular ejection fraction in LV angiography between the groups.
