Objective: Comparative evaluation of the impact of renal denervation versus pharmacological treatment with sympathetic nervous system (SNS) blockers on blood pressure variability in patients with resistant hypertension. Design and method: 75 patients with resistant hypertension without comorbidities after a 3-week standardized treatment with Losartan, Amlodipine and Indapamide and confi rmation of their resistance were randomized into three groups, depending on medication supplimented to the previously administred: group I M - selective I1-imidazoline agonist Moxonidine, group II B – cardioselective beta-blocker Bisoprolol, group III D – renal artery denervation (RDN). Blood pressure variability assessed by ambulatory blood pressure monitoring (ABPM) were determined at baseline, 3 and 6 months follow-up. Results: The media/day and media/night systolic blood pressure (SBP) variability increased at the baseline in all three groups was reduced statistically signifi cant from 3 months of monitoring, reaching the maximum effect towards the end of the study, when its normal values were recorded in all observational groups. Although treatment group supplimented with Moxonidine demonstrated an effect superior to that with Bisoprolol, and RDN - superiority to both, all three schemes had an authentic dynamics in improving SBP at 6 months of evaluation (p<0,001) (Fig.1). The evolution of diastolic blood pressure (DBP) media/day and media/night variability noted a benefi cial effect, starting with 3 months, the improvement of this parameter being maintained until the end of the study. Although the reduction of DBP variability was statistically authentic in all three groups at all stages of evaluation, the Bisoprolol treatment group noted a smaller effect in improving this parameter, the higher net effect being manifested by the RDN patients group (p<0,001) (Fig.2). Conclusions: RDN in patients with resistant hypertension reduced statistically signifi cant SBP and DBP variability starting with 3 months of follow-up and reaching maximum effect at the end of the study, simultaneously demonstrating superiority over treatment with SNS blockers. |
