摘要

Background: Renal denervation (RDN) is effective to lower systolic blood pressure (SBP) in essential hypertension. However, patient selection under medications remains an important unmet clinical need. Methods: This multicenter study aimed at observing whether preprocedural features associated with increased renin-angiotensin-aldosterone activity influence RDN response. This study enrolled the patients who underwent RDN for uncontrolled hypertension. Medical records were reviewd and patients were divided into 2 groups depending by meeting any of the following conditions prior to RDN: (1) >10 mmHg of office SBP reduction after aldosterone inhibition, (2) aldosterone-renin ratio >30 or (3) slow flow on the renal angiogram. RDN responders were defined by a reduction in 24-hour mean ≥6 mmHg or by ≥1 class of antihypertensive drug withdraw. Results: A total of 46 patients were enrolled, of which 27 (59%) were in control group A and 19 (41%) in group B. The baseline age, gender, office and 24-hour SBP (mean 140.0 ± 12.8 mmHg vs. 144.0 ± 16.5 mmHg, p = 0.577) were comparable, while the number of prescribed drug classes was fewer in group A (4.0 ± 1.3 vs. 4.9 ± 0.9, p = 0.014). The proportion patients with prescribed aldosterone antagonist or high aldosterone-renin ratios were higher in group B. At 12 months post RDN, the results were significantly better in group B in terms of mean change in office SBP (12.4 ± 23.5 mmHg vs. 29.9 ± 25.5 mmHg, p = 0.046) and the proportion of RDN responders (51.9% vs. 89.5%, p < 0.001). Conclusion: RDN was more effective in patients with any of 3 clinical indices.
