Thyroid hormones (THs) influence almost all the body cells and tissues' differentiation, growth, and energy metabolism. Consequently, excess THs are expected to lead to profound organ function, regulation, and hemodynamic changes. In addition to their roles in metabolism and thermoregulation, THs play critical role in maintaining cardiovascular homeostasis through both genomic and non-genomic mechanisms. Receptors for THs are expressed in myocardial and vascular endothelial tissues, allowing fluctuations in circulating hormone levels to directly influence cardiovascular function. Excess TS induces a hyper-dynamic cardiovascular state, characterized by increased ventricular contractility and improved systolic and diastolic performance. The chronotropic and inotropic properties of THs result in dysregulation of blood pressure, heart rate, contractility, cardiac output, and systemic vascular resistance. This could lead to serious consequences such as cardiomyopathy, heart failure, and life-threatening arrhythmia, ultimately contributing to cardiocirculatory collapse and cardiac death. The management of TS necessitates a systematic approach that emphasizes the significance of resuscitation and identification of the underlying causes. It is crucial to prioritize assessing cardiac function in patients with TS. This review explores the clinical impact of TS on the heart and its clinical repercussions, emphasizing the intricate molecular and pathophysiological mechanisms and the interplay between TS and key cardiovascular parameters.

This review synthesizes current evidence on the bidirectional interplay between gut dysbiosis and the dysfunction of major organ systems-liver, lungs, kidneys, brain, and heart-during sepsis. We explore how gut-derived factors such as microbial translocation, endotoxins, and altered metabolite production exacerbate systemic inflammation and organ injury.
