Hypothyroidism and subclinical hypothyroidism and their influence on autonomic cardiovascular regulation and metabolism

The aim of this review is to expose different opinions in the literature on influence TH and TSH autonomic vegetative regulation cardiovascular function metabolism marked subclinical hypothyroidism (sHT). Hypothyroidism causes changes hemodynamics lipid metabolism, which are predisposing risk factors for diseases. Subclinical proceeds asymptomatically but there system its regulation, as well a possible need hormonal treatment. Although according sources social age groups studied heterogeneous tests have been used investigate no single model investigation therapeutic behavior, especially sHT, has yet established. Heart rate variability (HRV) determined by balance afferent sympathetic parasympathetic influences cardiac structures can be stratification complications patients with hypothyroidism. Early detection dysfunction treatment may improve overall prognosis quality life sHT limit rates morbidity mortality these patients.
