Device-based treatment for hypertension
Autonomic imbalance is thought to play an important role in the pathophysiology of hypertension. Despite the availability of diverse pharmacological options, non-adherence to medication or inability to tolerate current pharmacological therapies has led to the development of various device-based therapy options. Inhibiting components of the sympathetic nervous system offers a unique opportunity to target the ‘neural’ component of the neurohormonal axis. Combining novel drug-, device-, and procedure-based strategies with improved utilization of existing therapies (including appropriate attention to diet, exercise, and weight control) may result in improved outcomes. This chapter discusses the rationale and current experimental and clinical data of several novel device-based treatment options—renal nerve ablation, carotid body ablation, carotid baroreceptor stimulation, and central arteriovenous anastomosis.
