My LAD is severely calcified. I learned this from tests done. To make the story short, I had some miscommunications with doctors so I never got the answers I needed. I feel nervous pushing the matter. They have not talked about any kind of treatment! Should they not try stents or bypass surgery? Are there reasons that they only use medications? I am afraid that I will have a heart attack. Also, I know that I am reaching stage 4 heart failure. They have not referred me to advanced care?
