Abstract/OtherAbstract:
BACKGROUND: Renal sympathetic denervation (RDN) reduces sympathetic activity and blood pressure (BP) in patients with resistant hypertension. The present study aimed to investigate the effects of RDN on HR and other electrocardiographic parameters. METHODS: 136 patients aged 62.2±0.8years (58% male, BP 177±2/93±1mmHg) with resistant hypertension underwent RDN. BP and a 12-lead electrocardiogram (ECG) were recorded before, 3months (n=127), and 6months (n=88) after RDN. RESULTS: After 3months (3M) and 6months (6M), systolic BP was reduced by 25.5±2.4mmHg (p<0.0001) and 28.1±3mmHg (p<0.0001). HR at baseline was 66.1±1beats per minute (bpm) and was reduced by 2.6±0.8bpm after 3months (p=0.001) and 2.1±1.1bpm after 6months (p=0.046). Patients with HR at baseline between 60-71bpm and ≥71bpm had a reduction of 2.9±7.6bpm (p=0.008) and 9.0±8.6bpm (p<0.0001), respectively, whereas in patients with baseline HR<60bpm HR slightly increased after 3months (2.7±8.4bpm; p=0.035). Neither baseline HR nor change of HR correlated with the reduction of systolic BP. The PR interval was prolonged by 11.3±2.5ms (p<0.0001) and 10.3±2.5ms (p<0.0001) at 3 and 6months after RDN, respectively. CONCLUSIONS: Renal sympathetic denervation reduced heart rate and the PR interval as indicators of cardiac autonomic activity.
