Do Different TSH Suppression Levels Effect Heart Rate Variability and QT Dispersions in Patients with Differentiated Thyroid Cancer?
The aim of this study was to investigate changes in heart rate variability (HRV) and QT dispersion (QTd) in patients with differentiated thyroid cancer at different TSH suppression levels. The study included 125 DTC patients, who had been on TSH suppression treatment (TSHST) for at least 1 year. The...

The study included 125 DTC patients, who had been on TSH suppression treatment (TSHST) for at least 1 year. The patients were categorized into three groups: patients with TSH < 0.1 mIU/L (n:30), those with TSH 0.1 to 0.5 mIU/L (n:56), and those with TSH 0.5 to 2 mIU/L (n:39). The first two groups were classified as suppression groups, and the last as replacement (control) group. All patients underwent 12-lead electrocardiogram (ECG) recording and 24-hour rhythm holter echocardiography analysis.
The HRV results derived from a 24-hour rhythm holter did not exhibit any significant difference (
< 0.05). In dispersion evaluations, the QTd was significantly longer in the suppression groups (groups 1 and 2), than in the replacement group (group 3) (
< 0.001 and p:0.002, respectively). The same was found for corrected QT dispersion (QTcd) (
< 0.001 and p: 0.008, respectively). In multivariate linear regression analysis, TSH was found to affect QTd (β = -0.299;
= 0.002) and QTcd (β = -0.300;
= 0.002) values independently.
In this study, it was shown that in patients with DTC receiving TSHST, QT dispersion prolonged as the TSH suppression level increased. Especially in high-risk DTC patients, evaluation of QTd may be useful in terms of evaluating cardiovascular risk and regulating TSHST level.</description><identifier>ISSN: 0743-5800</identifier><identifier>ISSN: 1532-4206</identifier><identifier>EISSN: 1532-4206</identifier><identifier>DOI: 10.1080/07435800.2024.2383669</identifier><identifier>PMID: 39051971</identifier><language>eng</language><publisher>England</publisher><ispartof>Endocrine research, 2024-07, p.1-8</ispartof><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><cites>FETCH-LOGICAL-c187t-194fea5f7ade13f25b3a03e32e95ce8df13d6a9d8e3012131ee75e7084b863803</cites><orcidid>0000-0002-0008-2742 ; 0000-0001-7700-645X ; 0000-0003-3786-1421</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27924,27925</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/39051971$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Çelik, Semih</creatorcontrib><creatorcontrib>Uç, Ziynet Alphan</creatorcontrib><creatorcontrib>Candan, Özkan</creatorcontrib><title>Do Different TSH Suppression Levels Effect Heart Rate Variability and QT Dispersions in Patients with Differentiated Thyroid Cancer?</title><title>Endocrine research</title><addtitle>Endocr Res</addtitle><description>The aim of this study was to investigate changes in heart rate variability (HRV) and QT dispersion (QTd) in patients with differentiated thyroid cancer at different TSH suppression levels.
