Nature already does this. Not often, I’m told by my cardiologist, but occasionally.
I had a heart attack in 1989. It left me with a circular section of scar tissue on my heart that was not quite 2 inches in diameter. They monitored it via PET scans, angiograms and something called MUGAs for several years and by 1995 the scar tissue had been completely replaced by new viable beating muscle. After watching it for an another 2 years, the cardiologists declared my heart to be in pre-heart-attacked condition. My heart has repaired itself, new blood vessels feed the new tissue and the old clotted and damaged coronary blood vessels have atrophied back to virtual non-existence.

I think it’s just genes.

From the viewpoint of genetics and possibly epigenetics your medical history makes you a person of great interest to researchers in regenerative medicine. A cardiac biopsy would be ideal, IMHO, but a blood sample or cotton swab from the inside of your cheek might do for now. I'm pretty sure folks at the Broad Institute and Howard Hughes Medical Institute, among others, would love to hear from you. They may make it worth your time.

If yor're interested in regenerative medicine, then check the NY Times article linked in comment# 1.

The cardiologist already did a biopsy telling me they needed to check on something.
Do you have any idea how much a biopsy hurts? It’s like someone ripping tissue from you with needle nose pliers.
I switched doctors after I finally figured out that I was just his lab rat.
