BACKGROUND The cardiovascular effects of transitions from exogenous subclinical hyperthyroidism to short-term overt hypothyroidism in patients treated for differentiated thyroid carcinoma remain unclear. The present study aims at evaluating the changes in multidirectional myocardial strain using two-dimensional (2D) speckle tracking during this controlled transition from exogenous subclinical h...
BACKGROUND In spite of the salt iodization, iodine deficiency disorders (IDD) have not been sustainably eliminated in China. There are coastal areas with low iodized salt coverage rates (iodine nutrition is inadequate) and other areas with excessive amounts of iodine in the drinking water.

Introduction: Different studies have demonstrated that maternal thyroid dysfunction during pregnancy is associated with adverse obstetrics and fetal outcomes. There is no international consensus regarding to use a guidelines for screening in high risk women. The aim of the present study was to determine prevalence of thyroid disorders in high and low risk pregnant women. Methods: In a cross-se...
Atrial fibrillation occurs in 10 - 15% of patients with hyperthyroidism. Low serum thyrotropin concentration is an independent risk factor for atrial fibrillation. Thyroid hormone contributes to arrythmogenic activity by altering the electrophysiological characteristics of atrial myocytes by shortening the action potential duration, enhancing automaticity and triggered activity in the pulmonary...
Diabetes mellitus (DM) and thyroid dysfunction (TD) are two common endocrine disorders. The unrecognized subclinical TD may adversely affect metabolic control and increase cardiovascular risk. Our aim was to investigate the prevalence of TD in patients with type 2 diabetes mellitus in an observational cross-sectional study. Clinical and laboratory evaluation was performed to 205 consecutive out...
This Study was performed to evaluate the effect of atenolol on the serum concentration of TT4 and TT3 in subclinical hyperthyroid patients. Due to the i n s u fficient information about the effect of atenolol on serum level of these hormones, the aim of this research was to shade some light on the subject. Fifteen subclinical hyperthyroid patients entered this study. Each patient received ...
