Effectiveness and Safety of BiSAAE for Resistant Hypertension.

Resistant Hypertension Clinical Trial

Official title:
Effectiveness and Safety of Bilateral Superselective Adrenal Arterial Embolization (BiSAAE) for Resistant Hypertension

Clinical Trial Summary

Hypertension is a common problem, affecting >1.1 billion people worldwide. Unfortunately, fewer than one in five treated patients with hypertension have their blood pressure (BP) under control. The increasing number of people with uncontrolled BP despite the use of three or more antihypertensive agents at optimal or maximally tolerated doses, with one of those agents preferably being a diuretic has been described as the resistant hypertension (RH). Achieving BP control is essential because patients with hypertension who have uncontrolled BP have significantly higher rates of all-cause, cardiovascular, heart disease and cerebrovascular disease mortality compared to normotensive individuals, whereas mortality risk in patients with well-controlled BP does not differ from that in normotensive individuals. There are a number of potential factors that contribute to the suboptimal control of hypertension, including medication non-adherence and prescribing inertia. This highlights the limitations of purely pharmacological approaches for the effective management of hypertension. In fact, the activation of the renin-angiotensin-aldosterone system (RAAS) and sympatho-adrenomedullary system play a pathogenic role in triggering and sustaining RH. Superselective adrenal arterial embolization (SAAE) is a catheter-based percutaneous transluminal procedure which selectively injects ethanol into adrenal artery to ablate part of the adrenal gland for suppression of excessive aldosterone and catecholamines. Over the last decade, unilateral SAAE has emerged as a potential treatment option for patients with primary aldosteronism. Whether this approach can be extrapolated to patients with RH is unclear. We thus set out to perform a randomized trial to compare the safety and efficacy of bilateral SAAE with antihypertensive medications in treating RH.
