概括
接受TSH抑制治疗的甲状腺癌患者表现出延长的QT分散与增加的TSH抑制. 这一发现表明,评估QT分散可能有助于评估差异化甲状腺癌 (DTC) 患者的心血管风险.
科学领域:
- 心脏病学 心脏病学
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
背景情况:
- 差异化甲状腺癌 (DTC) 治疗通常涉及TSH抑制疗法 (TSHST).
- TSHEST对心血管的影响,特别是关于心率变化 (HRV) 和QT分散 (QTd) 的影响,需要进一步调查.
- 了解这些影响对于优化治疗和患者管理至关重要.
研究的目的:
- 调查TSH抑制水平与DTC患者HRV和QTd变化之间的关系.
- 为了确定TSH抑制强度是否会影响心脏电生理学参数.
- 评估QTd作为DTC患者进行TSHEST的心血管风险生物标志物的潜力.
主要方法:
- 分析了125名DTC患者的队列,这些患者至少接受了TSHEST一年.
- 根据TSH水平,患者被分为三组:<0.1 mIU/L,0.1-0.5 mIU/L和0.5-2 mIU/L.
- 进行了12导电图和24小时空心监测;测量了HRV和QTd.
主要成果:
- 在TSH抑制组中没有观察到HRV的显著差异.
- 与替代组 (0.5-2 mIU/L) 相比,在较高的TSH抑制组 (<0.1和0.1-0.5 mIU/L) 中,QTd和更正的QTd (QTcd) 显著延长.
- 多变量回归分析表明,TSH水平独立地影响了QTd和QTcd.
结论:
- 在DTC患者中,TSHST与随着TSH抑制水平的增加而延长的QT分散有关.

Synthesis and Regulation of Thyroid Hormones
4.4K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Functions of Thyroid Hormones
2.7K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Increased pulse rate
651
Tachycardia is a condition marked by an abnormally fast or irregular heart rate, surpassing the typical resting rate. In adults, tachycardia is characterized by a pulse rate ranging from 100 to 180 beats per minute. The increased heart rate can result in inadequate blood flow to various body parts, ultimately diminishing the oxygen supply to organs and tissues.
Many factors can elevate the risk of developing tachycardia. These include advanced age, a family history of arrhythmias, and an...

Decreased pulse rate
536
Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...

Antiarrhythmic Drugs: Class III Agents as Potassium Channel Blockers
956
Class III antiarrhythmic drugs are a group of medications that can prolong action potentials in the heart. They achieve this by blocking potassium channels or enhancing inward currents from sodium channels. However, these drugs have a unique property of "reverse use-dependence," which is most pronounced at slower heart rates and can lead to torsades de pointes—a specific type of arrhythmia. However, it is essential to note that excessive QT interval prolongation—a measure of...

Factors Influencing Heart Rate
2.6K
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...
