Thyroid Hormones and Cardiovascular Function and Diseases

Area of Science:

• Cardiology and Endocrinology
• Molecular and Cellular Biology

Background:

• Thyroid hormone (TH) receptors are integral to cardiovascular (CV) and vascular tissues.
• Even minor TH level fluctuations can significantly impact CV physiology.
• Thyroid dysfunction is linked to endothelial dysfunction, altered blood pressure, and myocardial issues.

Purpose of the Study:

• To provide clinicians with an overview of thyroid hormone perturbations in cardiovascular disease.
• To synthesize current knowledge on the relationship between thyroid function and CV conditions.
• To highlight potential therapeutic roles of TH in managing CV disease.

Main Methods:

• Literature review of experimental data and clinical trials.
• Synthesis of existing research on thyroid hormone and cardiovascular interactions.
• Analysis of mechanisms linking thyroid dysfunction to CV pathologies.

Main Results:

• Thyroid dysfunction contributes to CV disease through mechanisms like endothelial dysfunction and altered heart function.
• Cardiac disease can induce changes in TH levels, such as low triiodothyronine syndrome, increasing mortality risk.
• Experimental and clinical evidence suggests TH may have beneficial effects in treating CV disease.

Conclusions:

• Thyroid hormone plays a critical role in cardiovascular health and disease.
• Understanding TH perturbations is essential for managing patients with CV conditions.
• Further research into TH's therapeutic potential in cardiovascular medicine is warranted.
