Lupus is known to cause heart disease...

I have very high cholesterol, like awful, despite eating well. So far blood pressure is low. But I have had Pericarditis

absolutely, I experience all of them as well, then I get sever anxiety because I feel like I'm dieing and that just makes things worse, its like a never ending cycle, most times I have to go to my safe space and calm down, it takes a wile but I finally do..

Same here! Praying for you!
