This is a very wide ranging and broad term - but it looks like I can now officially say that I have it!! asymptomatic (meaning, without symptoms) CVD! I have had a high cholesterol reading for over 30 years now - and recently decided to have a Calcium Score test done. I had not even heard of this before this and asked my Doctor ( who always wanted to put me on statins) if I could do it. Turns out that I now have a nice CT scan of my heart showing where all the artery hardening has occurred over the years - and will have a treadmill type test in a week or so to see what artery narrowing I have.
Probably most of you ( depending on age) all also have some degree of artery hardening - you just don't know it. But unfortunately for me, I now do - so I can see that this will have some effect on my running Yet - to be determined and I am not sure that I will get much of an answer from GPs as to how much effect it will have on my activities. They still seem to think that my maximum HR is 220-age =150!!
