Отдаленные результаты ренальной денервации и их половые особенности: данные трехлетнего наблюдения

Aim . To study the long-term outcomes of renal denervation (RDN) within 3-year follow-up with an assessment of blood pressure (BP) changes, the severity of target organ damage and the levels of pro- and anti-inflammatory cytokines in patients with resistant hypertension (RH), taking into account sex characteristics. Material and methods . A total of 42 patients with RH were examined at baseline, 1, 2, and 3 years after RDN on the background of antihypertensive therapy. Twenty-four-hour BP monitoring, echocardiography, assessment of creatinine level and estimated glomerular filtration rate (eGFR), as well as determination of some cytokines (interleukin (IL)-1β, 6, 10, tumor necrosis factor-α) were performed. Results . There was a persistent BP decrease in men and women for three years compared with the initial level by an average of 17 [4; 31]/10 [0; 18] mm Hg (p 0,05), IL-10 — from 5,8 [3,2; 8,2] to 2,8 [2,6; 2,9] pg/ml (p=0,000), correlating with IL-6 dynamics. Conclusion . Three years after RDN, there is a persistent decrease in mean 24-hour BP, regardless of sex. In women, a more pronounced BP variability decrease is observed, while in men — regression of left ventricular mass. There is no significant decrease in eGFR in the long-term period. The decrease in proinflammatory cytokines maintains, and in some cases becomes more pronounced within three years after RDN.
