[Structural and functional myocardial alterations in patients with arterial hypertension associated with thyroid pathology under conditions of the Far North].

The remodeling types of left ventricle (LV), types and periodicity of heart arrhythmias have been studied in patients with arterial hypertension (AH) associated with thyroid pathology (mainly autoimmune thyroiditis (AIT)), residing in the Far North. It is shown, that in patients with AH associated with thyroid pathology, residing in Far North, defects of LV geometry, adverse in prognostic plan, are revealed significantly more often. The functional conditions of thyroid gland influences on distribution of LV geometry types (concentric LV hypertrophy is registered significantly more often at hypothyroidism). Predominant type of heart arrhythmias in patient with AH and AIT is superventricular extrasistoly (SVE). At presence of thyroid dysfunctions SVE number grows in 1.2 times.
