Left ventricular wall myocardium structural and functional indices change in patients with arterial hypertension and subclinical hypothyroidism treated with hypotensives

Abstract

Aim. To assess the left ventricular wall myocardium structural and functional indices change over time in patients receiving hypotensive treatment for arterial hypertension associated with subclinical hypothyroidism. Methods. Sixty eight patients with arterial hypertension and subclinical hyperthyroidism were distributed to two groups. Patients of the group 1 (37 patients) received amlodipine (5-10 mg/day) and indapamide (1.5 mg/day), patients of the group 2 (31 patients) received lisinopril (5-10 mg/day) and indapamide (1.5 mg/day). Carotid artery ultrasonography and echocardiography were performed using «Philips» HD-11 XE (USA) scanner on the baseline and after 18 months of treatment. Results. Initial parameters of the left ventricular wall myocardium in all patients were comparable. Significant increase in early diastolic left ventricular filling velocity by 5.2%, decrease of late diastolic filling velocity by 11.4%, increase of peak velocities ratio on the mitral valve by 19.7% were revealed in patients of group 1 after 18 months of treatment compared to baseline. Increase in early diastolic left ventricular filling velocity by 7.0%, increase of peak velocities ratio on the mitral valve by 13.9% were registered in patients of group 2. No signs of concentric left ventricle remodeling were revealed. The share of patients with eccentric hypertrophy was not altered (18.9 and 12.9%, respectively). Conclusion. Treatment with amlodipine + indapamine and lisinopril + indapamine during 18 months improves left ventricle diastolic function.
