About Hypertension

Everyone experiences daily events that raise their blood pressure. For most of us, these increases are temporary and have no lasting impact on our health. However, patients with hypertension face higher risks of heart attack, stroke, heart failure, kidney disease and death. Medtronic has developed a novel approach to hypertension that selectively quiets hyperactive renal nerves.


Hypertension, or high blood pressure, is a common disorder in which blood pressure remains abnormally elevated for a sustained period of time.


The onset of hypertension has been correlated with several factors, including genetics, aging, diet and lifestyle.


Although an asymptomatic condition, when left untreated, chronic hypertension poses serious health risks including significantly increased risk of heart attack, stroke, heart failure, kidney disease and death. Hypertension is the leading attributable cause of death in the world, affecting approximately 1.2 billion people worldwide1.

One of the body's primary methods for controlling blood pressure involves the sympathetic nervous system. This system impacts the major organs that are responsible for regulating blood pressure: the brain, the heart, and the kidney.

One key player in long-term blood pressure regulation is the kidney. Renal nerves communicate information from the kidney to the brain, and vice versa. In people with hypertension, the renal nerves are hyperactive, which raises blood pressure.
