Hypothyroid and heart issues

[CustardTarts]

I read an article recently, as in today, on the forum. where someone mentioned heart condition and linking it to thyroid.

I am not yet diagnosed with hypothyroid, although after previous conversations on here believe I am. Last check was TSH just under the 5. My levels have been slowly rising since 2014, when I Iast started accessing my blood results. Not sure when they started to rise prior to that date.

However the post I was referring to was very interesting to read, although the thread now closed.

In October 2022 I had cause to call an ambulance, and although they didn't feel the need to take me in for the reason I had called them for, they did a full check up, like they do. They had concerns with an ECG they did. Apparently I had a left bundle block. I was taken to hospital for further checks. To cut a long story short, three months later in Feb 2023 I had a pacemaker fitted. To be honest being told I needed one in the first place left me in complete shock, as I have never had any issues with my heart.

So beggers the question, could this have been thyroid related? Also in 2022 about the same time I was diagnosed with type 2 diabetes, again could this all be related?

I must say thank you for the info on here is so useful, even if I cant take it all in😄

i've no idea about the specific heart issue you have in relation to hypothyroidism ..... but in case it's useful this post has a list of papers about thyroid/ heart : healthunlocked.com/thyroidu...

this paper says there’s is a link between hypothyroidism and right bundle block. It’s given as an example. Not sure about left bundle block

Hi CustardTartsI have LBBB It was found at the same time as my persistent Afib with no thyroid problems but now I'm Afib free my LBBB doesn't cause me any problems at all touch wood. I hope this helps with your question.

I can't answer your question, other than with a maybe. I was diagnosed with hypothyroidism about 25 years ago. Last year I learnt I had LBBB. So I've been pondering the same thing.

I’ve been hypothyroid and diabetic over 2 decades, and been investigated re.cardio etc as I have high BP and HR post Covid (4 1/2 years ago). Been diagnosed with postural hypotension but have hypertension at rest, but heart doesn’t seem to have expected ‘blocks’ etc…sorry can’t be more explicit but reports are in abbreviations that my LC brain fog just cannot get to grips with. Meanwhile my GP, who various specialists have released me back to, sees the high HR and is convinced it’s ’over medication On levothyroxine’…I think he must have read the linked paper but my TSH is not responding as he’d hoped. Reduced levo.down from 100 to 75 mcg ( I do take T3 15 mcg too) and all he got was an increased TSH from 0.02 to 0.03…so at that rate even 0 levo. wouldn’t increase the TSH to the desired 0.5 in the paper!

I don't know much about issues with the bundle block but I personally developed AFib after 7 years of untreated subclinical hypothyroidism and my cardiologist told me that hypothyroidism is a a contributing factor in heart problems. They encouraged me to get treatment for me thyroid and I believe that has helped keep my heart arrhythmia mostly at bay.

thank you that interesting to know. I have no history of heart issues and read somewhere on here about a possible link with thyroid issues. My thyroid has been on an upward spiral for at least ten years, but not enough to consider treating. I have loads of symptoms but just not reached that threshold yet. So one wonders how much damage that has caused
