As far as I understand, micro-vascular angina has no relation with vase spasms which take place in the coronary arteries while the micro-vascular happen in the very small capillaries
Anyway this is what I have found:
"Two characteristic abnormalities in myocardial capillaries in human diabetes have been found in the myocardium: endothelial swelling and/or degeneration and thickening of the capillary basement membrane"

Ange,
I think that nobody can warrant that you will get better if you low your glucose, but it seems that you can be worst if it stay high or increase.

I didn't realize there was any connection between the two. I have vasospasms myself and deal with the chest pains almost daily. I love it when I have a strectch without any angina. The only correlation I can think of is perhaps diabetes causes muscle cramps. The heart is muscle. But I don't know. This is interesting. Who told you there was a connection?
