Observational StudyRenal sympathetic denervation: early impact on ambulatory resistant hypertension.
Although guidelines recommend ambulatory blood pressure (BP) monitoring (ABPM), few data are available regarding the effects of renal denervation (RDN) on 24-hour ABPM values. A total of 44 patients with mean systolic BP ≥135 mm Hg on ABPM despite adequate therapy were included. Basal systolic BP (SBP) and diastolic BP (DBP) were 154±11 mm Hg and 86±12 mm Hg, respectively. ⋯ Neither the number of ablation points nor the amount of impedance drop was predictive of response. Only approximately half of patients with resistant hypertension responded to RDN. However, in these responders, a remarkable reduction of 24-hour BP occurred as early as 1 month after RDN.
