Alteraciones cardiovasculares causadas por hipotiroidismo clínico y subclinico

Hypothyroidism is an endocrine disorder in which the thyroid gland has a diminished function; havingas a consequence the loss of homeostasis of the body, therefore, altering its proper functioning.To diagnose this disease, physical examination, blood tests and thyroid stimulating hormone testsare utilized. Since the cardiovascular system and the thyroid gland are physiological related, thegeneral disorders of the thyroid gland greatly affect the cardiovascular system. The intracellularand extracellular mechanisms of thyroid hormones are detailed; and, using this information, all themorphological and physiological changes that this pathology causes in the heart and on smooth musclecells are explained. In addition, the implications of the disease on the myocardium, on hemodynamics,its relation to congestive heart failure, hypertension and general effects on blood vessels are revealed,with the objective of describing the relationship between clinical and subclinical thyroid hypofunctionas a determining risk factor for the development of cardiovascular disorders.
