Cardiomyopathy V: Interprofessional Care

Cardiomyopathy V: Interprofessional Care

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Heart Failure I: Introduction

Heart Failure I: Introduction

Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

Functions of Thyroid Hormones

Functions of Thyroid Hormones

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...

Synthesis and Regulation of Thyroid Hormones

Synthesis and Regulation of Thyroid Hormones

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...

Pathophysiology of Cardiac Performance

Pathophysiology of Cardiac Performance

Typical heart performance is influenced by heart rate, rhythm, myocardial contraction, and metabolism or blood flow. The cardiac muscle exhibits distinct electrophysiological features, including pacemaker activity and calcium channel control, which play a vital role in the heart's response to various drugs. The autonomic nervous system, comprising the sympathetic and parasympathetic branches, regulates heart rate. Sympathetic activation increases heart rate, while parasympathetic activation...

The Thyroid Gland

The Thyroid Gland

The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Area of Science:

Cardiology
Endocrinology
Regenerative Medicine

Background:

The heart possesses a natural capacity for healing, potentially mirroring embryonic development.
Thyroid hormone (TH) plays a crucial role in heart maturation and may aid in adult heart repair.
Dysregulation of TH and thyroid hormone receptor (TR) homeostasis is linked to myocardial damage and heart failure.

Purpose of the Study:

To explore the reparative role of thyroid hormone in adult heart regeneration.
To investigate if TH treatment can restore a fetal phenotype in damaged myocardium.
To evaluate the clinical efficacy of TH in patients with acute myocardial infarction.

Main Methods:

Examined analogies between damaged myocardium and embryonic heart development.
Assessed the impact of TH-TR homeostasis on myocardial regeneration.
Conducted a Phase II, randomized, double-blind, placebo-controlled study (THiRST) in acute myocardial infarction patients.

Main Results:

TH treatment promotes rebuilding of injured myocardium by reactivating developmental gene programming.
Reduced biologically active triiodothyronine (T3) levels correlate with increased morbidity and mortality post-myocardial infarction.
The THiRST study is evaluating the therapeutic potential of TH in heart regeneration.

Conclusions:

Thyroid hormone holds significant potential for regenerating diseased hearts.
Targeting TH-TR pathways may offer novel therapeutic strategies for heart repair.
Further clinical investigation is warranted to confirm TH's regenerative capacity in heart disease.
