Modifications In The Heart Caused By Clinical And Subclinical Thyroid Disorders

Abstract

Background: Hypothyroidism, an endocrine condition, occurs when the thyroid gland underperforms, disrupting homeostasis and normal bodily functions. It is diagnosed through clinical symptoms and measurement of thyroid hormone levels in the blood.

Objective: This abstract aims to detail the morphological and physiological changes in the cardiovascular system caused by hypothyroidism and elucidate the intracellular and extracellular mechanisms of thyroid hormones.

Methods: A comprehensive analysis of the physiological interplay between the thyroid gland and the circulatory system was conducted, focusing on how hypothyroidism affects cardiovascular health. The impacts on hemodynamics, myocardial structure, and function were reviewed, alongside considerations of hypertension and vascular health.

Results: Hypothyroidism influences cardiovascular health through altered hemodynamics, myocardial dysfunction, and vascular changes. The condition is associated with congestive heart failure, hypertension, and compromised blood vessel integrity. Both clinical hypothyroidism and subclinical thyroid dysfunction are identified as significant risk factors for developing cardiovascular disorders.

Conclusion: Hypothyroidism exerts a profound effect on cardiovascular function through direct and indirect mechanisms. Understanding these relationships is crucial for identifying and managing cardiovascular complications associated with thyroid dysfunction.
