Predictors of blood pressure response: Obesity is associated with a less pronounced treatment response after renal denervation

Objectives The purpose of this study was to identify predictors of BP response. Background Catheter‐based renal denervation (RDN) causes significant blood pressure (BP) reductions in a large number of patients with resistant hypertension. Methods One hundred one consecutive patients with resistant hypertension who underwent RDN with the Symplicity™ catheter were included in this retrospective study. Primary endpoint was the change in office systolic BP after 6 months. Uni‐ and multivariate logistic regression analyses were performed to detect baseline predictors of a significant BP response 6 months after RDN (age, gender, office and ambulatory BP, renal function, body mass index [BMI], diabetes mellitus, antihypertensive medication, number of ablations). Results The procedure was technically uneventful in all patients. Mean BP at baseline was 166.6/90.2 ± 22.5/16.4 mmHg and decreased by −14.7 (P
