Recent technologic advances rekindled interventional management of resistant hypertension, either by carotid baroreceptor activation or renal sympathetic denervation. Interventional techniques result in impressive falls in office blood pressure (BP); however, ambulatory BP reductions are rather modest. This disparity between office and ambulatory BP reductions is observed with antihypertensive drugs, but at a much lower degree. Available explanations are not convincing, therefore, we propose that sympathetic overactivity may partially explain this divergence. Further studies are needed to prove or disprove our hypothesis.
