Heart Disease and MS

So I started having some issues with my heart and am being sent on for some testing. So I decided to search the internet and see if MS had anything to do with heart disease and well apparently it does. I also asked my cardiologist and she said yes MS can affect the heart. I swear I have never seen anything in all of my MS research mention this until I specifically searched for Heart Disease and MS. I mean when you search for info on MS a lot of stuff pops up but I've never seen anything about the heart.
Has anyone been affected by heart disease due to their MS?
