Catheter-based renal denervation (RD) has been introduced recently as a potentially effective invasive treatment of refractory hypertension. The proportion of patients with severe hypertension suitable for RD is not clear. The aim of this study was to identify what percentage of patients has truly resistant essential hypertension and are thus potentially eligible for RD. We investigated 205 consecutive patients referred to a university hypertension center for severe hypertension within 12 months. Ambulatory 24-h blood pressure (BP) monitoring (24 h ABPM), secondary hypertension screening and compliance to treatment testing (by use of plasma drug level measurements) were performed in all patients. Fifty-seven patients (27.8%) did not have truly resistant hypertension (RH) based on clinical BP. Among the remaining 122 patients (59.5%) with RH confirmed by 24 h ABPM, 50 patients (24.4% of the original cohort) had a secondary cause of hypertension and in 27 (13.2%) non-compliance to treatment was confirmed. Thus, only 45 patients (22%) had truly resistant essential hypertension and were considered for RD. Only one-third (n=15, 7.3% of the original cohort) was, however, finally referred for RD (14 were excluded due to contraindications for RD and 16 refused the invasive treatment). In conclusion, thorough examination of severe hypertension including 24 h ABPM, secondary hypertension exclusion and drug compliance testing before considering RD reveals that majority of these patients are not suitable for RD. Specifically, compliance to treatment testing should be mandatory in order to identify eligible candidates for RD.

We did a subject-level meta-analysis of the changes (Δ) in blood pressure (BP) observed 3 and 6 months after renal denervation (RDN) at 10 European centers. Recruited patients (n=109; 46.8% women; mean age 58.2 years) had essential hypertension confirmed by ambulatory BP. From baseline to 6 months, treatment score declined slightly from 4.7 to 4.4 drugs per day. Systolic/diastolic BP fell by 17.6/7.1 mm Hg for office BP, and by 5.9/3.5, 6.2/3.4, and 4.4/2.5 mm Hg for 24-h, daytime and nighttime BP (P0.03 for all). In 47 patients with 3- and 6-month ambulatory measurements, systolic BP did not change between these two time points (P0.08). Normalization was a systolic BP of <140 mm Hg on office measurement or <130 mm Hg on 24-h monitoring and improvement was a fall of 10 mm Hg, irrespective of measurement technique. For office BP, at 6 months, normalization, improvement or no decrease occurred in 22.9, 59.6 and 22.9% of patients, respectively; for 24-h BP, these proportions were 14.7, 31.2 and 34.9%, respectively. Higher baseline BP predicted greater BP fall at follow-up; higher baseline serum creatinine was associated with lower probability of improvement of 24-h BP (odds ratio for 20-μmol l(-1) increase, 0.60; P=0.05) and higher probability of experiencing no BP decrease (OR, 1.66; P=0.01). In conclusion, BP responses to RDN include regression-to-the-mean and remain to be consolidated in randomized trials based on ambulatory BP monitoring. For now, RDN should remain the last resort in patients in whom all other ways to control BP failed, and it must be cautiously used in patients with renal impairment.
