About this trial

Long-standing hypertension may cause an impairment in microvascular coronary circulation which is involved in many different cardiac conditions. Renal denervation (RDN) has been successfully proven as a valuable and powerful therapeutic choice to consider for patients with resistant hypertension; moreover this procedure looks promising in other cardiac disease such as heart failure and atrial fibrillation, given its ability to downregulate sympathetic nervous system The aim of this study is to explore the effect of renal denervation and blood pressure control on coronary microvascular dysfunction.

This is a multicenter, prospective, non randomized, open-label, interventional study. Consecutive patients with resistant hypertension, non obstructive coronary artery disease and documented microvascular dysfunction will be enrolled. Patients will undergo renal denervation by Spyral Symplicity 3 and re-assessment of coronary microvascular function 12 months after the procedure. Primary endpoint will be the difference in average index of microcirculatory resistance value.

Eligibility criteria

Qualifiers

Non obstructive stable coronary artery disease (CAD) on invasive coronary angiography (defined as the absence of either >50% angiographic stenosis or any flow limiting lesion on functional evaluation)

Suspected diagnosis of difficult to control/ resistant hypertension for which renal denervation by radiofrequency ablation with Spyral Symplicity 3 could be considered.

Disqualifiers

Initiation of either nitrates, beta-blocker or calcium channel blocker less than 30 days before the end of the rule-in phase

Physiological assessment performed during first medical contact documenting preserved coronary microvascular function

Physiological assessment performed at the "first contact" hospitalization followed by modification of medical therapy during the rule-in phase, before RDN

Acceptable blood pressure control after medical treatment optimization
