Zusammenfassung
Die Ursachen einer therapierefraktären Hypertonie sind multifaktoriell bedingt, wobei eine entscheidende pathophysiologische Rolle der Aktivierung des sympathischen Nervensystems zukommt. Erste Daten zeigen, dass mit der Durchführung einer interventionellen renalen sympathischen Denervation bei Patienten mit therapierefraktärer arterieller Hypertonie eine signifikante Reduktion der Sympathikusaktivität sowie eine deutliche und nachhaltige Blutdrucksenkung erzielt werden kann. In die aktuell laufende Symplicity-HTN-2-Studie werden Patienten eingeschlossen, bei denen trotz einer 3-fach antihypertensiven Therapie keine adäquate Blutdrucksenkung (Gelegenheitsblutdruck >160 mmHg systolisch, bei Patienten mit Diabetes mellitus Typ 2 >150 mmHg) zu erzielen ist. Das plausible pathophysiologische Konzept und die sichere, einfache und effiziente Anwendung eröffnen weitere Einsatzgebiete, beispielsweise bei Patienten mit Diabetes mellitus, chronischer Herzinsuffizienz und terminaler Niereninsuffizienz.
Abstract
Hyperactivity of the sympathetic nervous system has been shown as one of the factors contributing to the complex pathophysiology of resistant hypertension. Preliminary data demonstrate that in these patients catheter-based renal sympathetic denervation can significantly attenuate sympathetic activity and result in marked and sustained blood pressure reduction. The ongoing randomized Symplicity-HTN-2 trial enrolls patients with office systolic blood pressure of 160 mmHg or more (150 mmHg for patients with type 2 diabetes), despite at least a triple antihypertensive drug regimen. Based on a plausible pathophysiological concept, interventional sympathetic renal denervation is safe, effective and easy to perform and might offer benefits in other areas as well, e.g., in patients with diabetes, chronic heart failure or end-stage renal disease.
