My grandmother had it done (decades of farm cooking) and she said it was fine. I think a lot of the recovery time was precautionary, since the artery is in a fragile state and needs to heal, lest it form another "scab" in the form of plaque.

That Diet Doctor article was intriguing about the K2 factor. I didn't start supplementing that until a few years ago; it could turn out to be as crucial as Vitamin D3, which complement each other.

Perhaps all of us have to deal with how we used to eat. May you sail through this and have less worry as a result.
