Cardiovascular disease research should focus more on patients’ T3 levels than TSH

Science has already shown that at T3 is more important than TSH to the functional parameters of the cardiovascular system: At the molecular and tissue level, the T3 hormone directly affects the cardiovascular system in a myriad of important ways (see "Low T3’s effects on the cardiovascular system.") Why, then, when researchers shift their focus …

Low T3 effects on the cardiovascular system

When people think of cardiovascular symptoms and thyroid hormones, they usually think first about hyperthyroidism (EXCESS T3 thyroid hormone). However, hypothyroidism (DEFICIENT T3 thyroid hormone) has an equally powerful effect on the heart and blood vessels. It can just be slower, more long-term, and less dramatic. Did you know? Heart failure occurs in hypothyroidism. (See …

Interpreting Free T3 and Free T4 in therapy

Hypothyroidism is a thyroid hormone insufficiency, so it's only logical to measure the success of therapy by the goal: T4 and T3 thyroid hormone sufficiency. Especially T3 sufficiency, the active hormone. Lab tests like Free T3 and Free T4 can indicate "relative" T3 and T4 sufficiency in bloodstream ... but one has to carefully interpret …
