Heart failure due to fetal gene reactivation?

Would you believe that the onset of heart failure in many adults is brought on by a fetal heart-cell enzyme? That's the conclusion from U.S. researchers that believe most heart failure in adults is due to a carryover from pre-infant biology.

The enzyme, according the the research, is associated with a condition called cardiac hypertrophy, and that condition is a precursor to many forms of congestive heart failure. With heart disease being leading cause of death here in the U.S. , this research is sure to get quite a bit of attention as a result.

The heart expresses genes that are generally only expressed in fetal development when heart failure begins, and scientists have not know why this happens to this point. The discovery of this enzyme's effects here may be of huge importance soon (my guess).
