The modern vision concerning the physiological actions and pathological relevance of endocrine cardiac system is a very complex one. Decreased or increased action of thyroid hormone (hypo‐ or hyperthyroidism) on different cellular and molecular pathways in the heart plays an important role in the development and progression of myocardial remodelling and heart failure. Cardiovascular signs and symptoms that accompany both hyperthyroidism and hypothyroidism are presented, highlighting that correction of thyroid dysfunction most often reverses the abnormal cardiovascular hemodynamics.
