Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to evaluate the efficacy and safety of renal denervation (RDN) in patients with isolated diastolic hypertension (IDH). The randomized, sham-controlled, multicenter clinical trial will recruit 87 participants (58 in the treatment group and 29 in the sham control group) to assess changes in blood pressure and adverse events over a 6-month follow-up period. The study is expected to provide new evidence for the use of RDN as a treatment for IDH.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Renal Denervation Group

Patients receiving renal denervation using the Symplicity Spyral™ multi-electrode renal denervation system.

Group Type EXPERIMENTAL

Renal Denervation

Intervention Type PROCEDURE

Renal denervation performed using the Symplicity Spyral™ multi-electrode renal denervation system, which is approved for interventional treatment of hypertension. This procedure involves catheter-based radiofrequency ablation of the renal nerves to reduce sympathetic activity and lower blood pressure.

Renal Angiography

Intervention Type PROCEDURE

A sham procedure involving renal angiography without the application of radiofrequency energy. This control intervention is used to maintain blinding.

Sham Control Group

Patients undergoing renal angiography only (sham procedure).

Group Type SHAM_COMPARATOR

Renal Angiography

Intervention Type PROCEDURE

A sham procedure involving renal angiography without the application of radiofrequency energy. This control intervention is used to maintain blinding.
