Abstract
Summary Background Carotid baroreflex activation lowers blood pressure and might have potential application for the treatment of resistant hypertension. We did a proof-of-principle trial with a novel endovascular baroreceptor amplification device, MobiusHD (Vascular Dynamics, Mountain View, CA, USA), in patients with resistant hypertension. Methods CALM-FIM_EUR was a prospective, first-in-human, open-label study done at six European centres. Eligible patients were adults with resistant hypertension (office systolic blood pressure ≥160 mm Hg despite taking at least three antihypertensive agents, including a diuretic). MobiusHD devices were implanted unilaterally in the internal carotid artery. The primary endpoint was the incidence of serious adverse events at 6 months. Secondary endpoints included changes in office and 24 h ambulatory blood pressure. This trial is registered with ClinicalTrials.gov, number NCT01911897. Findings Between December, 2013, and February, 2016, 30 patients were enrolled and underwent successful implantation. Mean age was 52 years (SD 12), 15 patients (50%) were men, and mean antihypertensive use was 4·4 drugs (1·4). Mean office blood pressure was 184/109 mm Hg (18/14) at baseline and was reduced by 24/12 mm Hg (13–34/6–18) at 6 months (p=0·0003 for systolic and p=0·0001 diastolic blood pressure). Mean baseline 24 h ambulatory blood pressure was 166/100 mm Hg (17/14) at baseline and was reduced by 21/12 mm Hg (14–29/7–16) at 6 months (p<0·0001 for systolic and diastolic blood pressure). Five serious adverse events had occurred in four patients (13%) at 6 months: hypotension (n=2), worsening hypertension (n=1), intermittent claudication (n=1) and wound infection (n=1). Interpretation In patients with resistant hypertension, endovascular baroreceptor amplification with the MobiusHD device substantially lowered blood pressure with an acceptable safety profile. Randomised, double-blind, sham-controlled trials are warranted to investigate the use of this treatment further. Funding Vascular Dynamics.
