Renal Denervation: A Future Treatment for Hypertension?

blood-pressure-squareDo you suffer from hypertension? If you are:

  • Between the ages of 20 and 80
  • Have consistently high blood pressure
  • Are willing to participate in a clinical trial

You may be eligible to participate in one of Emory’s research studies. Emory is currently enrolling patients in a clinical trial related to hypertension. Patients, either on or off blood pressure medications, will be enrolled in a randomized study in which participants may undergo an investigational procedure called renal denervation. This procedure is being investigated to determine its potential impact on blood pressure.

What is renal denervation?

Renal denervation is an investigative procedure that is intended to decrease activity of the nervous system in the kidneys. Renal nerves transmit information between the kidneys and the brain via the sympathetic nervous system. These nerves often signal an increase in blood pressure. Patients with hypertension tend to have hyperactive nerves in the renal arteries, and denervation is thought to decrease the activity of these overactive nerves.

How is the procedure performed?

The procedure is minimally invasive. A narrow tube is inserted through a small puncture in the leg artery and delivers radio-frequency energy in an attempt to deactivate the nerves surrounding the kidney arteries. The procedure only requires several hours of bedrest once complete. Participants will be followed closely through outpatient follow-up visits conducted at Emory University Hospital Midtown.

Takeaways from Dr. Lundberg’s Hypertension Chat

Hypertension Live ChatThanks to everyone who joined us Tuesday, June 23, for our live online chat on “Things You Never Knew About Your Blood Pressure” hosted by Dr. Gina Lundberg of the Emory Women’s Heart Center!

To prevent hypertensive heart disease, it’s important that you consistently keep your blood pressure nice and low. Dr. Lundberg noted that the good news is that 80% of all cardiovascular deaths could be prevented with better lifestyle – healthy eating and exercise – and better blood pressure monitoring, and discussed ways to help you achieve this goal.

If you missed this chat, be sure to check out the full list of questions and answers on the hypertension chat transcript.

Here are just a few highlights from the chat:

Question: Are there any foods I should incorporate into my diet to control high blood pressure?

Gina Lundberg, MDDr. Lundberg: There is no one food you can eat to lower your blood pressure. The best thing you can do is to make a change to your diet as a whole. I’d recommend following the DASH (Dietary Approaches to Stop Hypertension) Diet. This diet is very high in fruits and veggies (potassium and magnesium). Potassium correlates to lower blood pressure. You can find more info about the DASH Diet here.

 

Question: Is it normal for my blood pressure and heart to race? I exercise regularly.

Gina Lundberg, MDDr. Lundberg: Yes, when you exercise routinely your heart rate will go up slower but you will still get to a peak heart rate with prolonged exercise. Many people feel their heart is racing with sudden activities such as walking up the stairs, but this is common as there is no warm up prior to the activity.

 

Question: How much does stress really impact blood pressure?

Gina Lundberg, MDDr. Lundberg: Stress can raise your blood pressure and your heart rate from internal release of adrenaline. Some people over-respond to their adrenaline and get dangerously high blood pressures very suddenly. An exercise stress test can simulate stress on the body and help determine if blood pressure is getting dangerously high. Sudden surges in blood pressure can cause stroke or heart attack. Chronic stress can lead to chronically elevated mild to moderate hypertension which can also be dangerous for your eyes, brain, heart, and kidneys.

Thanks again to everyone who joined us live for the chat! If you have additional questions for Dr. Lundberg, feel free to leave a comment in our comments area below.

Things You Never Knew About Your Blood Pressure

blood pressure live chatYou’ve probably heard high blood pressure, or hypertension, called the “silent killer” because it can damage your arteries and organs without you ever realizing something is wrong. Not only can it damage your heart, but it can also cause stroke, kidney damage, vision loss, memory loss, erectile dysfunction, fluid buildup in the lungs and angina.

Join us on Tuesday, June 23, at 12:00 p.m. for a live, interactive web chat about “Things You Never Knew About Your Blood Pressure.” Dr. Gina Lundberg will be available to answer questions and discuss various topics about high blood pressure. For instance, did you know that common over the counter medication can increase your blood pressure? Did you know you can have high blood pressure and never experience any symptoms at all?

During this interactive web chat, you’ll be able to ask questions and get real-time answers from our Emory Healthcare professional.

What Can You Do to Fight High Blood Pressure?

hypertensionDid you know that over 30% of adults (over the age of 20) have high blood pressure, also known as hypertension?* Did you also know that high blood pressure is a leading cause of heart disease, stroke and kidney disease? The good news is that high blood pressure can be prevented if you educate yourself and take the recommended course of action from your physician.

What is High Blood Pressure (Hypertension)?
Blood pressure is the amount of the blood force against the arterial walls. The upper number is the pressure when the heart is contracting and the lower number is when the heart is at rest.

High blood pressure, or hypertension, is when one or both numbers are elevated. Normally it should be under 140/90 mmHg, and anything above this is considered elevated.

What are the symptoms of High Blood Pressure?
Many people think that you can tell if you have high blood pressure by experiencing symptoms like headache, nose bleeds or chest pains, but the reality is that hypertension is a symptomless disease. When blood pressure is elevated and is not treated, you heart, brain and kidneys can suffer the consequences and you do not know it.

Get checked for High Blood Pressure
Everyone should know what their blood pressure numbers are and get treated if elevated or prevent it from being elevated. Factors like age, obesity, family history, increased salt consumption, medications, lack of exercise, alcohol, drugs, renal disease and hormonal abnormalities can contribute to the development of high blood pressure.

What can I do to prevent high blood pressure?

  1. Reduce salt (sodium) intake – Salt is known to retain water and increase blood pressure and the United States is considered a society that consumes a high salt diet. Most of the salt we eat comes from processed and packed foods. The recommendation is to consume less than 1,500 mg of sodium a day, to get an idea a teaspoon of salt has 2,400 mg of sodium!
  2. Consume Potassium – Potassium counterbalances the effects of sodium, at least 4,700 mg daily is advised. Some of the foods rich in potassium are potatoes, greens, bananas, tomatoes and oranges. Patients with renal disease should discuss with their doctors about their potassium intake.
  3. Limit alcohol consumption – Men should limit their alcohol intake to 2 drinks per day and women to 1 drink daily.
  4. Exercise! Exercise! Do at least 150 minutes of moderate intensity aerobic physical activity to keep your circulation, lungs and heart healthy.

If despite of trying your best to prevent hypertension your blood pressure is elevated, your doctor can work with you to find an appropriate medical regimen to control it. Medications that help your body eliminating the sodium excess, retaining potassium or relaxing your blood vessels can be prescribed to you. Together with diet and exercise, medications can control hypertension and prevent heart attacks and strokes.
