Can damaged heart repair itself?

【Expert answer】
Any Q

The heart is unable to regenerate heart muscle after a heart attack and lost cardiac muscle is replaced by scar tissue. Scar tissue does not contribute to cardiac contractile force and the remaining viable cardiac muscle is thus subject to a greater hemodynamic burden.


Can heart recover from damage?

The answer is most likely yes. The heart muscle begins to heal soon after a heart attack. It usually takes about eight weeks to heal. Scar tissue may form in the damaged area, and that scar tissue does not contract or pump as well as healthy muscle tissue.

Can the heart heal it self?

Unlike most other cells in the human body, heart cells do not have the ability to self-repair or regenerate effectively, making heart attack and heart failure severe and debilitating.

How long does it take for the heart to regenerate itself?

These remarkably high rates imply that the entire heart is replaced approximately every 3 years during normal homeostasis, and that all cardiac myocytes lost to an infarction could be replaced within 3 weeks.
