Thyroid hormones are crucial for cardiovascular health. This review explores how thyroid dysfunction impacts cardiovascular disease, emphasizing monitoring thyroid-stimulating hormone in aging populations.
Area of Science:
- Cardiovascular Physiology
- Endocrinology
Background:
- Thyroid hormones regulate cardiovascular development and function.
- Thyroid function tests are essential in patients with cardiovascular disease.
- Hypothyroidism, hypertension, and cardiovascular disease prevalence increase with age.
Purpose of the Study:
- To review the effects of thyroid hormones on normal cardiovascular function.
- To assess the role of overt and subclinical thyroid dysfunction in cardiovascular diseases.
Main Methods:
- Literature review of contemporary understanding.
- Analysis of the impact of thyroid hormonal status on cardiovascular physiology.
Main Results:
- Thyroid hormones influence all cardiovascular system components.
- Subclinical and overt thyroid dysfunction can contribute to cardiovascular disease.
- Monitoring thyroid-stimulating hormone is vital for aging populations.
Conclusions:
- Understanding thyroid hormone's cardiovascular impact aids clinical decision-making.
- Integrated management of thyroid status and cardiovascular disease is recommended.
- Further research into thyroid dysfunction and cardiovascular disease is warranted.

Functions of Thyroid Hormones
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...

Synthesis and Regulation of Thyroid Hormones
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...
