Is it dangerous?

[Buffy6956]

Hello I’m hoping someone can give me answers. I had a stent fitted to my RCA in March and my left circumflex has 40% non significant plaque tested by wire study. All my other arteries are clear. I had a call from my dr last week saying that my thyroid has become borderline under active so therefore he wants to start me on 25mcg Levothyroxine. My TSH level was 7.2 and my T4 was 12.1. Now I have done some research which is suggesting that it could be dangerous to take Levothyroxine in over 50’s who have a history of CAD which I am and do have. So what then am I supposed to do? as it seems it’s dangerous to “not” treat it as well..? I feel really upset about all this as all I want to do is continue with my diet excercise medication etc to get better then get hit with this quandary. Can anyone shed any light on this please th

Hello... I am not expert but know three people who have had all of their thyroid removed. In comparison to them your Thyroxine dose is very low. High doses seem linked to AF in particular and less so with CVD. There is an excellent HU Thyroid UK forum and it is probably worth posting there. Good luck.

Glad to see you are getting a number of responses from Thyroid UK...

My wife had underactive thyroid. I believe it is important to get that corrected else you will have further Cardiac problems down the road. As you are borderline I would think you will be fine, so I wouldn't worry too much. The dose of tablets can be difficult to determine, so we always found best left to how the suffered feels. Too cold increase to hot decrease. You will know how you feel, listen to your body and your mood. Too little and you can't think properly and your eyes get baggy, and you put on weight, too much and you lose weight.

It's a difficult call and I am not a medic, but have much experience living for 20 years with the condition you find yourself in, but is best you get specialist opinion.
