Renal sympathetic denervation as second‐line therapy in mild resistant hypertension: A pilot study
Bibliographic record
Abstract
BACKGROUND: Catheter-based renal sympathetic denervation (CRD) is associated with significant blood pressure (BP) reductions in patients with severe therapy-resistant hypertension (office systolic BP ≥ 160 mm Hg or ≥ 150 mm Hg in diabetic patients). Effects of renal denervation on BP in patients with milder forms of therapy-resistant hypertension have not been examined. We sought to investigate the feasibility, safety, and effectiveness of CRD in patients with longstanding mild hypertension despite treatment with ≥ 3 antihypertensive drugs. METHODS: Consecutive patients with office systolic BPs of 140-160 mm Hg despite ≥ 3 antihypertensive medications treated with CRD were included in this prospective study. Procedural safety and adverse events during follow-up were assessed. Clinical evaluations were performed at baseline, 3, and 6 months to determine changes in office systolic BPs, 24-hr ambulatory BPs, and medication doses. RESULTS: Twenty patients (mean age 60.6 ± 10.8 years; 45% female) treated with an average of 5.4 ± 1.5 antihypertensive drugs were treated with CRD. The procedure was successful in all patients. There were no procedure- or device-related complications. BP at baseline was 148.4/83.0 ± 6.6/11.0 mm Hg and decreased by 5.7/0.6 ± 20.0/8.3 mm Hg (P = 0.2) and 13.1/5.0 ± 13.6/8.3 mm Hg (P < 0.01) at 3 and 6 months, respectively. Comparing baseline and 6-month follow-up, mean ambulatory 24 hr-BP was reduced by 11.3/4.1 ± 8.6/7.3 mm Hg (P < 0.01). Four patients were able to reduce antihypertensive medications prior to their 3-month visit. CONCLUSION: As in patients with severe treatment-resistant hypertension, CRD is a safe and effective treatment for patients with milder drug-resistant hypertension.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
