Objective. To evaluate the efficiency of radiofrequency denervation of the renal arteries in patients with resi-stant arterial hypertension during a three-year follow-up. Materials and methods. The study involved 40 patients with resistant arterial hypertension aged 27 to 70 years (mean age 54.91±9.77 years) while receiving three or more antihypertensive drugs (including diuretic) in optimal doses. The conditions for inclusion in the study were considered resistant arterial hypertension with blood pressure (BP)>160/100 mm Hg, intact kidney function - glomerular filtration rate (MDRD)>45 ml/min - and the absence of secondary hypertension. All patients had sympatic radiofrequency denervation of renal arteries; its efficiency later was estimated according to the clinical measurement and ambulatory blood pressure monitoring (ABPM). Results. The level of office BP reliably differed initially and after 3 years: DSBP -34.48±6.44 mm Hg (p=0.001), DDBP - 22.29 mm Hg (p=0.001). According to ABPM results, reliable dynamics of systolic blood pressure was not observed. The data of DBP at night were significantly lower after 36 months; DDBP was -5.37±9.77 mm Hg. Conclusions. A marked decrease in the data of office SBP and DBP was observed, which proves the long-term efficiency of radiofrequency denervation of the renal arteries in patients with resistant hypertension. Accor-ding to ABPM results after 36 months, a significant decrease was registered among the DBP indicators at night and daytime.
