Great question. It is possible but rare, in the cases that excess thyroid
hormones generate a cardiomyopathy
, or weak heart muscle, usually by sustained rapid heart rates, excessive amounts (more than 10 thousand) of PVC's daily or very rarely stress
cardiomyopathy. In people with underlying blockages of the heart arteries, leakage of cardiac enzymes could be more common in the settings that I mentioned.
