High blood pressure is becoming more common around the world. Many people try to control it by eating healthy, exercising, or taking medicine.
But even with these efforts, some people still struggle to bring their blood pressure down.
Having high blood pressure that isn’t controlled can raise the chances of getting heart disease, kidney problems, or having a stroke.
But now, there is new hope. A study published in the medical journal JAMA shares a new treatment that could help.
This new treatment is a simple medical procedure. It’s not surgery and doesn’t need big cuts. It works kind of like putting in a stent, which is used to open up blocked blood vessels. The procedure is called renal denervation, or RDN.
RDN is for people whose blood pressure stays high even after taking medications. It targets the nerves near the main blood vessel that goes to the kidneys. These nerves play a role in raising blood pressure. RDN can be used on its own or with medicine.
Here’s how it works: A doctor puts a thin tube, called a catheter, into a small opening in your wrist or groin. The tube is carefully guided to the blood vessel near the kidney.
Then, sound energy or radio waves are sent through the tube to reduce the activity of the nerves around the blood vessel. This helps lower blood pressure. Once both kidneys are treated, the tube is removed.
In a recent study, 224 people with high blood pressure took part in a trial to see if RDN would help. Dr. Stephen Jenkins from Ochsner Health helped lead the study. He explained that RDN is a new option for people who find it hard to control their blood pressure with medicine alone.
This wasn’t the first study on RDN. Earlier trials showed it worked for people with different types of high blood pressure, even in mild cases. The most recent trial, called Radiance II, proved that RDN can lower blood pressure and keep it lower for at least two months after the procedure.
Not only that, but three more studies, published in JAMA Cardiology and based on more than 500 patients, also found that RDN worked well in lowering blood pressure in many types of cases.
There are other things people can do to help with high blood pressure too. Some research says that drinking tea and eating meals earlier in the day might help. Cutting down on added sugars in food is also important. And for people with diabetes, getting enough vitamin D might help improve blood pressure.
This new RDN treatment gives people with tough-to-control high blood pressure another option. It might help lower their risk of heart and kidney problems in the future.
