New York — A survey recently conducted on behalf of Medtronic and in partnership with the National Kidney Foundation (NKF), the largest kidney organization in the U.S., found that physicians are seeking new approaches to lowering patients’ blood pressure. The survey of over 200 cardiologists and nephrologists also showed that more than 60% of patients aren’t aware of non-pharmacological alternatives intended to manage hypertension, presenting an opportunity for greater patient-physician dialogue around all available treatment options, including optimal lifestyle modification and the renal denervation procedure called Symplicity Spyral.^™

Almost all (95%) of physicians surveyed agree there is an increased urgency to act now to reduce the prevalence of patients with uncontrolled hypertension. According to the World Health Organization, an estimated 1.28 billion adults worldwide have hypertension, most living in low- and middle-income countries¹. Hypertension affects almost half of adults in the U.S., and among those, only 22% have their hypertension under control.² Uncontrolled blood pressure can lead to largely preventable events such as heart attack, stroke, and heart failure and is the second leading cause of kidney failure in the U.S.^3,4 Small changes in blood pressure can have lasting effects. In fact, reducing blood pressure by 10 mmHg can lead to a relative risk reduction of cardiovascular events by over 20%.⁵

Current Treatment Options Aren’t Enough

Current hypertension care strategies, including lifestyle changes and medications, are not always enough to help patients manage their blood pressure. Only 40% of survey respondents think that current treatment options are adequate, and 75% agree that a significant portion of their patients (regardless of medication levels) are unable to reach their target blood pressure goals. These challenges speak to the possibility that patients may benefit from an adjunctive treatment option to better manage their blood pressure.

Renal Denervation as a Non-Medical Alternative to Manage Hypertension

The approval of renal denervation, or RDN, comes at a time when most physicians (98%) would value more solutions to manage hypertension. Medtronic’s Symplicity Spyral™ blood pressure procedure, which was approved by the U.S. Food and Drug Administration in 2023, is an innovative, minimally invasive procedure that delivers radiofrequency energy to nerves near the kidneys that can become overactive and contribute to high blood pressure. After sedation, the physician inserts a single thin tube (known as a catheter) into the artery leading to the kidney. Once the tube is in place, the physician administers energy to the system to calm the excessive activity of the nerves connected to the kidney. The tube is removed, leaving no implant behind.

“Hypertension is a growing global health issue, and we now have more treatment options than ever before,” said Jason Weidman, senior vice president and president of the Coronary and Renal Denervation business within the Cardiovascular Portfolio at Medtronic. “These survey findings validate what we are seeing play out in doctor’s offices across the country - patients and their physicians are actively seeking new therapies like RDN. Medtronic is proud to partner with NKF to drive awareness of hypertension treatment gaps and new potential solutions."

With any new therapy or product, patient preference and shared decision-making are critical components of developing a successful care plan. More than half (62%) of surveyed physicians don’t think that patients are aware of non-pharmacological alternatives that may help in the treatment of their high blood pressure, indicating a need for better dialogue and awareness of treatment options like RDN. Additionally, according to results from a Medtronic-led patient preference study, approximately 76.5% of patients would be willing to consider an interventional approach such as RDN with reductions in office blood pressure anticipated at 10 mmHg.⁶

About this survey

The survey was conducted online within the United States on behalf of Medtronic and in partnership with the National Kidney Foundation. The objective was to gather feedback from the physicians within and outside NKF’s membership in order to learn more about the unmet needs of hypertension management and considerations in offering patients a minimally invasive procedure.
