Traditional medical teaching is that humans die with the heart muscles that they are born with.
Therefore, heart muscles that die when a person has a heart attack, will never regenerate and result in permanent injury akin to formation of scar tissue on skin (although skin does have a limited capacity to regenerate which is why scars do not form after minor skin trauma).
An article published in the Journal, Science seeks to overthrow this concept.
The researchers in their article have demonstrated that there is limited regeneration of heart muscle after birth.
“We have taken advantage of the integration of carbon-14, generated by nuclear bomb tests during the Cold War, into DNA to establish the age of cardiomyocytes in humans. We report that cardiomyocytes renew, with a gradual decrease from 1% turning over annually at the age of 25 to 0.45% at the age of 75. Fewer than 50% of cardiomyocytes are exchanged during a normal life span.”
This finding opens up possibilities of targeting medications to regenerating the heart muscle that is destroyed in a heart attack, thereby preventing a host of complications including heart failure (post myocardial infarction congestive heart failure is the number one cause of heart failure in the United States and is the major contributer of morbidity & mortality after heart attack).
