Hypothyroidism is often associated with adverse cardiovascular risk factors such as high cholesterol together with hypertension, endothelial dysfunction, and other atherosclerotic cardiovascular risk factors. The changed hemodynamic characteristics result in reduced cardiac index, and the renal perfusion is impaired with hyponatremia, and low renin and aldosterone production. The ischemic abnormalities ...
