Abstract

Aim. To study the effect of renal denervation on blood pressure (BP), myocardium function and vegetative status in patients with resistant hypertension (HT).

Material and methods. Patients with a provisional resistant HT diagnosis (n=62; 41.3% male) were included into the study. 17 patients were selected for renal denervation after correction of previous antihypertensive therapy and examination to exclude symptomatic HT. Two patients refused the procedure, 1 patient hadn’t undergone renal denervation due to anatomical features (renal artery diameter <4 mm). Renal denervation was performed in 14 patients. Office and average daily BP, kidney function, the severity of left ventricular hypertrophy and heart rate variability were assessed initially and after the intervention.

Results. Office systolic BP (SBP) decreased from 165 to 150 mm Hg (p=0.016), diastolic BP (DBP) - from 110 to 95 mm Hg (p=0.019) 12 months after the renal denervation. Average daily SBP decreased from 148 to 137 mm Hg (p=0.092), average daily DBP - from 90 to 80 mm Hg (p=0.401). Plasma creatinine level and glomerular filtration rate remained within the reference range at a baseline and in 12 months. Left ventricular hypertrophy measured by echocardiography has not changed significantly. No significant heart rate variability dynamics has been found.

Conclusion. Renal denervation is a promising treatment for resistant HT. The effect of renal denervation on the dynamics of left ventricular hypertrophy and heart rate variability requires updating.
