Parameters of the left ventricular structure, arterial pressure level and their relation with the deposited catecholamines in the erythrocytes were studied in 50 patients of the age group 16–40 with the normal, higher-normal blood pressure and the 1st grade hypertension. There was structural remodeling of the left ventricle in the earlier steps of hypertension. Excentric remodeling was observed in 40 % of patients with higher-normal blood pressure. In the patients with 1st grade hypertension both remodelling types were observed in equal proportions. There is a relation between structural changes of the left ventricle and common deposited catecholamines in the erythrocytes.
