Assessment of effect of irbesartan and nebivolol on the left atrium volume and deformation in the patients with mild-moderate hypertension.

Abstract：

BACKGROUND:We aimed to assess the effects of irbesartan and nebivolol on the left atrium (LA) volume and deformation in the patients with mild-moderate hypertension. PATIENTS AND METHODS:The study comprised of 160 patients (mean age: 55.6±9.6 years), who had Stage 1 or 2 hypertension according to the European Society of Cardiology (ESC) and have not been receiving antihypertensive therapy. The patients were assigned to treatment groups; irbesartan (n=80) and nebivolol (n=80). The patients were clinically and echocardiographically reevaluated on the 6th and 12th months after the onset of treatment. RESULTS:There was no difference between the two treatment groups in terms of baseline demographic, clinical and echocardiographic characteristics. Moreover, no difference was observed between the treatment groups on the 6th and 12th months. Intragroup analyses revealed that systolic blood pressure (SBP) and diastolic blood pressure (DBP) significantly decreased in time and diastolic function parameters were improved. However, whilst significant increase was observed in conduit volume, decrease was observed in other volumes of the LA in the irbesartan and nebivolol groups. This significant change was observed on the 6th month in both treatment groups. LA global peak systolic strain (LAGLSs), LA global peak systolic strain rate (LAGLSRs), LA global peak strain rate during early ventricular diastole (LAGLSRe) and LA global peak strain rate (LAGLSRa) during late ventricular diastole (LAGLSRa) values began to be significantly increased after 6 months of treatment in both treatment groups. CONCLUSIONS:We found that nebivolol, which is a new generation beta blocker, is effective as irbesartan with proven efficacy in improving LA volume and LA myocardial performance in patients with mild-moderate hypertension. Moreover, we determined that strain and strain rate, which are the new echocardiographic parameters, are effective as LA volumes in assessing LA functions.
