Dolores,
They never diagnosed my chest pains prior to 1999 as having anything to do with heart either. I heard so many stories like yours from our friend, a nurse. She said that she cannot count how many times in her career she saw a patient with a chest pain being sent off back home, explained away as "stress", "ribbs", "indigestion" and similar nonsense. Only too see the same person wheeled back into the hospital on a gurney a few days later.
The only way around the incompetence of many doctors, is to scrutinize them, verify against published studies, and be skeptical to everything they say. In my case also, doing the opposite to what they advised helped a lot.
Vitamin K2 - absolutely! I think there is a very solid evidence behind it. Also it is well worth keeping track of once fasting insulin levels. It is not sugar peaks it is the insulin which seems to be one of the most important factors behind arterial plaque formation.
K2: seafood, organ meat, natto, egg yolks, butter from grass-fed cows (e.g. Irish butter), cheese.
D3 - dietary fat and cholesterol. Low cholesterol and low fat diet seem to impede D3 synthesis even under high exposure to the solar UV. (Note: D3 and K2 seem to get depleted by a high wheat consumption!)
Do not forget about vitamin A (liver, fish, carotenoids from carrots, peppers, yams etc but only in the presence of dietary fat!).
Best regards and best wishes to get better!
Stan
