• Uncontrolled hypertension drives the global burden of increased cardiovascular disease (CVD) morbidity and mortality. Although high blood pressure (BP) is treatable and preventable, only half of the patients with hypertension undergoing treatment have their BP controlled. The failure of polypharmacy to attain adequate BP control may be due to a lack of physiological response, however, medication non-adherence and clinician inertia to increase treatment intensity are critical factors associated with poor hypertension management. The long-time medication titration, lifelong drug therapy, and often multi-drug treatment strategy are frustrating when the BP goal is not achieved, leading to increased CVD risk and a substantial burden on the healthcare system. Growing evidence indicates that neurohumoral activation is critical in initiating and maintaining elevated BP and its adverse consequences. Over the past decades, device-based therapies targeting the mechanisms underlying hypertension pathophysiology have been extensively studied. Among these, robust clinical experience for hypertension management exists for renal denervation (RDN) and baroreflex activation therapy (BAT), carotid body denervation (CBD), central arteriovenous anastomosis, and to a lesser extent, deep brain stimulation. Future studies are warranted to define the role of device-based approaches as an alternative or adjunctive treatment option to treat hypertension. Systemic hypertension is a growing contributor to global disease burden and premature cause of death worldwide. The percentage of patients achieving target BP levels remains largely inadequate. Hypertension is characterised by activation of the sympathetic nervous system, with the magnitude depending on age and the disease severity. Device-based interventions have been extensively studied to directly target the relevant sympathetic neural pathophysiological mechanisms involved in BP control. Modulation of the chronic sympathetic outflow with CBD or BAT shows promise for the treatment of poorly controlled hypertension in addition to antihypertensive medicines. The BP response to device-based therapies appears variable and cannot be predicted before the procedure. Until more robust evidence related to patient selection, procedural and technical aspects is available, chemoreflex and baroreflex neuromodulation therapy should be restricted to randomised sham-controlled trials performed in experienced centres.
