Wonder if it's linked to Queuine Deficiency dysregulating tetrahydrobiopterin.

The heart cannot utilize phenylalanine appropriately when BH4 is dysregulated. Also why peroxynitrites build up causing arterial stiffening, calcification and scarring.

Cholestrol doesn't cause heart attacks, it's just trying to heal wounds, which is what it does. It's the unhealable calcified scars that is the problem.
