Evaluate the effects of renal sympathetic denervation on patients with resistant hypertension

Objective To observe the blood pressure and drug using whithin 6 months of renal sympathetic denervation(RDN) on patients with resistant hypertension. Methods 15 patients with resistant hypertension after renal sympathetic denervation were observed.The the blood pressure(BP), ratio of BP up to the standard,types of drug using and complications were observed before RDN and after RDN in 1, 3, 6months. Results The Systolic diastolic blood pressure before RDN and after RDN in 1, 3, 6months were(164±14)mm Hg,(138±11)mm Hg,(138±8)mm Hg,(135±7)mm Hg(P 0.05), the diastolic blood pressure before RDN and after RDN in 1, 3, 6months were(98±10)mm Hg,(84±9)mm Hg,(83±7)mm Hg,(81±8)mm Hg(P 0.05).The ratio of BP up to the standard were 66.7%, 80.0%, 86.7%(P0.05). The types of drug using were(3.6±0.9) kinds before RDN and decreased to(2.4±0.8) kinds after RDN(P 0.05).All patients had no complications. Conclusion RDN can be safety and effectively used in patients with resistant hypertension and the effects have Time continuity.
