title: [The effect of kordaron on thyroid function in patients with ischemic heart disease].
abstract: Thyroid function has been assessed in 56 patients with arrhythmic coronary heart disease (CHD) prior to and in the course of cordaron treatment. TTH level made up initially 1.39 +/- 0.27 IU/ml which was normal. T3 blood concentration was low--1.28 +/- 0.06 nmol/l; T4 was normal--128.26 +/- 4.9 nmol/l. It is stated that CHD patients with arrhythmia develop latent hypothyrosis of T3-low-syndrome type. Arrhythmia treatment with cordaron aggravates T3 deficiency as the drug inhibits T4 conversion into T3 in peripheral tissues. It also causes toxic damage to thyroid parenchyma resulting in higher TH levels in the blood. CHD patients receiving long-term cordaron (1 to 8 years) have clinical picture of manifest hypothyrosis. Cordaron molecules includes iodine macro-doses, but these fail to initiate autoimmune thyroid process.
