OpenAlex İngilizce

Objectives: In this study, it was aimed to evaluate the relationship between serum thyroid stimulating hormone (TSH) level and left ventricular strain parameters measured by the two-dimensional speckle tracking imaging among adults with subclinical hypothyroidism (SH). Materials and Methods:Forty patients with SH were divided into two groups according to TSH level (the first group: TSH values of 4.2-10.0mIU/L; the second group: TSH values >10 mIU/L).Besides, 20 (control group) ageand gender-matched healthy subjects were included in the study as the control group.Standard echocardiographic measurements and the two-dimensional speckle tracking imaging measurements of apical two and four cavities, systolic peak longitudinal strain (PLS) from shortaxis images, peak circumferential strain (PCS), global longitudinal strain and global circumferential strain were obtained.Results: Twenty patients were included in each group.In two-dimensional speckle tracking, PLS in the twodimensional speckle tracking imaging was shown to
