摘要

Autonomic sympathetic activation plays a key role in the pathophysiology of systemic hypertension and left ventricular hypertrophy. As shown in the Symplicity HTN-1 and HTN-2 trials, percutaneous renal denerva-tion (PRD) has proven to be an effective and safe method to treat patients with medically resistant hypertension and is considered to influence central sympathetic tone. In patients after renal denerva-tion, microneurography showed a gradual reduction in muscle sympathetic nerve activity in accordance with a modulation of central sympathetic tone. The effect on cardiac autonomic tone is not known. Heart rate variability (HRV) is a marker of cardiac autonomic activity. The present study assessed for the first time the effect of sympathetic renal denervation on heart rate dynamics in patients.
