High blood pressure is a growing global health concern. Despite efforts to control it through diet, exercise, and medication, many people still struggle with it.
Those with uncontrolled high blood pressure are at a higher risk of heart and kidney diseases, and strokes. However, a new study in the JAMA medical journal introduces a promising solution for managing this condition.
Innovative Procedure for High Blood Pressure
This new method is a minimally invasive procedure performed under the skin, resembling the insertion of a stent to unblock blood vessels. It’s particularly aimed at individuals whose high blood pressure remains high despite medication.
The procedure, known as renal denervation (RDN), uses sound energy to target the nerves linked to the main blood vessel leading to the kidneys. RDN can be used alone or in conjunction with blood pressure medications.
How Does RDN Work?
The RDN procedure is straightforward and doesn’t require a large incision. A catheter, a slim tube, is inserted through a small opening in the wrist or groin.
This tube reaches the blood vessel leading to the kidney, where either sound energy or radiofrequency energy is applied to the surrounding tissues. This action diminishes nerve activity, effectively reducing blood pressure. The catheter is then removed, having treated both kidneys.
Clinical Trial Results
A substantial clinical trial involving 224 patients with uncontrolled high blood pressure tested the effectiveness of RDN. Dr. Stephen Jenkins of Ochsner Health, a contributor to the study, highlighted RDN as a new option for those battling high blood pressure.
This procedure has shown promising results in reducing nerve activity that contributes to high blood pressure.
Earlier trials focused on patients with mild to moderate and resistant high blood pressure, showing positive outcomes.
The latest, more extensive trial, known as the Radiance II trial, confirmed its effectiveness in patients with uncontrolled high blood pressure, maintaining lower blood pressure levels for up to two months post-procedure.
Consistent Success in Various Studies
Additionally, three other studies on RDN published in JAMA Cardiology, encompassing data from over 500 patients, demonstrated consistent blood pressure reduction across various high blood pressure cases.
Broader Implications and Additional Resources
For those interested in blood pressure health, other studies suggest that drinking tea could help lower blood pressure, and early time-restricted eating might improve it.
It’s also worth noting research linking added sugar in diets to higher blood pressure and studies showing vitamin D’s potential to improve blood pressure in people with diabetes.
The significance of this study, published in JAMA, lies in offering a new, viable option for patients struggling to control their blood pressure, potentially leading to better management and reduced risks associated with high blood pressure.
