Cardiac Dysfunction

Meaning

Cardiac dysfunction refers to an impairment in the heart’s ability to effectively pump blood or to fill with blood, thereby compromising systemic circulation and oxygen delivery. This condition is fundamentally a physiological state where the myocardium’s mechanical or electrical properties are compromised, often leading to heart failure or arrhythmias. Within endocrinology, hormonal imbalances, such as thyroid disorders or growth hormone deficiencies, can directly contribute to or exacerbate this state by altering cardiac contractility and remodeling. Understanding this dysfunction is crucial for managing overall health, as the heart is central to the entire circulatory and endocrine transport system.
