    Low T3 post MI is associated with increased CHF, morbidity and mortality.  Article discusses thyroid hormones and cardiac function/remodeling post infarct.  The article also lays the ground work for a new study of T3 in patients post MI to be followed for 6 months.

PCOS LH insulin hypothyroidism androgens testosterone resistance

shared by Nathan Goodyear on 17 Dec 10 - No Cached
  • CONCLUSION: It appears that ovarian androgen excess in women with PCOS is mainly LH-dependent in Group 1 and insulin-dependent in Group 2. Enhanced adrenal activity may contribute to both hyperandrogenism and insulin resistance in this syndrome, and subclinical hypothyroidism may exist in affected subjects, especially of Group 1.

hypothyroidism hypothyroid T4 T3

shared by Nathan Goodyear on 20 Dec 10 - No Cached
  • The common feature of these disorders is a low level of circulating T3, with generally normal to slightly elevated blood T4 levels and either normal or slightly suppressed TSH levels. This pattern of altered thyroid hormone levels is generally agreed to be a result of impairment in extra-thyroidal peripheral metabolism

    thyroid replacement is not just about T4 (synthroid); but about T3, which is 5.4 x more potent

hypothyroid hypothyroidism T3 T4 rT3 cardiovascular disease CHF tachycardia

shared by Nathan Goodyear on 01 Feb 11 - No Cached
  • Patients with ventricular tachycardia demonstrated significantly lower serum values of FT3 and FT3/FT4, and significantly higher values of rT3. Serum thyroid hormone levels can provide a quantitative index for evaluating the severity of chronic heart failure and predicting ventricular tachycardia.
