Low T3 in the heart can cause heart failure
Low levels of T3 in the heart tissue can cause heart failure according to a study from the National Institute of Health and the American Diabetes Association.
Usually, thyroid hormones are measured in the blood, but researchers of this study have concluded that there is no coherence between the level of T3 in the blood sample and that, for example, in the heart tissue: a person with heart disease and low T3 in the heart tissue may have normal blood tests, these researchers say.
The study points out that there is clearly a need to pay more attention to the effect of low levels of T3 in the heart, and what role it plays in the development of heart failure.
The researchers state that many doctors fear T3-treatment, and doctors in general tend to completely avoid treating heart patients with thyroid hormones.
The scientists have obtained such good results in a study performed on rats with mild diabetes, so the next step is to do clinical trials on humans.
The purpose is to examine the extent to which heart failure is caused by a diagnosed disease, and to what extent it is actually caused by low levels of T3 in the heart.
