The Baroreflex in Hypertension.

Hypertension is a complex syndrome that increases the risk of developing other medical comorbidities and interacts with other medical conditions to increase the risk of target end-organ damage such as cardiovascular disease, stroke, and renal disease. Hypertension remains under-recognized and poorly controlled in the USA and worldwide. In some patients, hypertension is resistant to optimal medical therapy. Over the last few decades, there has been an increasing understanding of the role of the sympathetic nervous system in the development and maintenance of hypertension. This update reviews the physiology and role of the sympathetic nervous system in hypertension and pharmacological and interventional treatments directed at nervous system involvement in secondary hypertension.
