“Low thyroid hormone levels should be interpreted as a cardiovascular risk factor” (von Hafe M, 2019).
“Thyroid hormones modulate every component of the cardiovascular system necessary for normal cardiovascular development and function. When cardiovascular disease is present, thyroid function tests are characteristically indicated to determine if overt thyroid disorders or even subclinical dysfunction exists” (Grais, 2014).
Both overt and subclinical hypothyroidism and hyperthyroidism affect cardiovascular function.
“Diastolic function and systolic function are clearly influenced by thyroid hormones”
