High blood pressure, also called hypertension, is a common and dangerous health condition that affects millions of people around the world. If not managed properly, it can lead to serious problems like heart attacks, strokes, and kidney failure.
While many people are able to control their blood pressure with lifestyle changes and medication, others still struggle even with treatment. For these patients, a new medical procedure may offer fresh hope.
Researchers have recently studied a technique called renal denervation, or RDN, and found that it may help lower blood pressure in people who haven’t had success with medications alone. The results of a new clinical trial were published in the journal JAMA, and they show promising outcomes.
So, what is renal denervation? It’s a minimally invasive procedure that works by calming certain overactive nerves near the kidneys. These nerves are involved in raising blood pressure. By reducing their activity, doctors can help bring blood pressure down.
The procedure is fairly simple. Doctors insert a thin tube called a catheter through a small cut in the wrist or groin. They guide the catheter to the arteries near the kidneys, where they use sound waves or heat (called radiofrequency energy) to gently disrupt the nerves.
Once both kidneys have been treated, the catheter is removed, and the procedure is complete. Because it only requires a small incision, patients usually recover quickly.
In the most recent study, called the Radiance II trial, 224 people with high blood pressure that wasn’t responding to medication took part. After the procedure, many of them saw their blood pressure drop significantly, and the effect lasted for at least two months.
One of the study’s authors, Dr. Stephen Jenkins from Ochsner Health, explained that this technique could be a helpful new option for patients who haven’t been able to lower their blood pressure in other ways.
This trial wasn’t the first to test renal denervation. Two earlier trials had similar results, and together, these studies now include data from over 500 people. Across different patient groups—including those with mild, moderate, or severe high blood pressure—renal denervation has shown a steady ability to reduce blood pressure levels.
There are several advantages to this approach. First, it’s minimally invasive, which means less pain and a faster recovery compared to major surgery. Second, it can be used along with regular blood pressure medications, so patients don’t have to give up other treatments.
Third, it provides long-term results, helping to manage blood pressure over time—something that’s very important for preventing serious health issues.
For people who feel they’ve run out of options, renal denervation could be a life-changing solution. Although more research is needed to fully understand the long-term benefits and to make sure the procedure is as safe and effective as possible, the current findings are very encouraging.
With high blood pressure continuing to be one of the top causes of death and disease worldwide, new treatments like this are urgently needed. Renal denervation could be a valuable tool in helping patients live healthier, longer lives.
