Cell therapy using cardiac muscle cell aggregates improves heart function following a heart attack

In the event of a heart attack, the affected part of the heart muscle can no longer be supplied with oxygen and nutrients. As a result, the heart muscle cells (cardiomyocytes) die off. Scar tissue forms, and heart function is impaired. This often leads to chronic heart failure—also known in medical terms as cardiac insufficiency. It is one of the most common causes of death in the Western world.
