Heart Murmur/Hyperthyroidism

Posted by Lisa on July 04, 1999 at 15:03:53
Recent test discovered hyperthyroidism TSH level 12.99.  Prescribed synthroid (used for hyprothyroidism).  Synthroid should be used cautiously w/patients w/coronary artery disease & angina.  I have a functional heart murmur..concerned w/medication used that is for hypo & not hyper.  Could medication cause any damage to heart?

Hi Lisa,
   I too have thyroid disease.  Unless your lab standards are different, a TSH of over 4.2 is considered hypothyroidism, not hyper.  A TSH of below .4 is considered hyperthyroidism.  I'm not a doctor but have gone from hyper to hypo, so have had lots of TSH tests.

Thanks for your comments.  An elevated TSH does mean HYPO thyroidism.
I hope this has been useful. Feel free to write back with further questions. Good luck.
