You can’t fix a heart – can you? Scientists at the German Centre for Cardiovascular Research (DZHK) are currently working on a heart plaster that will bridge damaged tissue on the heart muscle. This is mainly the result of a heart attack. Approximately 200,000 Germans suffer a heart attack every year. However, thanks to very good emergency care nowadays, more than three quarters of them survive. However, damaged areas often remain on their heart muscle. They have lost their contraction strength forever. The heart muscle cells of adults are not able to divide. They are therefore unable to form new tissue. This results in a permanent loss of function, which puts strain on the remaining heart muscle. In about a quarter of infarct patients, this leads to chronic cardiac insufficiency. Claus F.
