What is kidney dysfunction, a new way to keep your blood pressure under control?
A minimally invasive procedure used to treat resistant high blood pressure, or high blood pressure that does not respond to other medications, kidney dysfunction occurs when the veins in the renal arteries located in the kidneys are obstructed. It effectively reduces the signals sent to the brain that contribute to high blood pressure. Considered a new method for controlling blood pressure, it was approved by the US FDA last November. Read on to know more about it.
Controlling hypertension is important as it remains the leading global cause of death and disability.
The United States Food and Drug Administration, in 2023, approved renal denervation – a catheter-based procedure that denerves the sympathetic nerves of the kidneys – as an adjunctive treatment for patients in whom lifestyle modifications and antihypertensive medications Does not control blood pressure adequately.
According to experts, controlling high blood pressure is important as it remains the leading global cause of death and disability, with more than half of hypertensive individuals failing to meet guideline-directed blood pressure goals.
Doctors say normalizing blood pressure is a significant health challenge driven by factors such as patient non-compliance, physician inertia and complex polypharmacy regimens. And hence, renal denervation has emerged as a novel interventional strategy for the management of treatment-resistant hypertension.
How does renal inhibition work?,
according to American Heart AssociationThe doctor threads a small catheter or tube through the blood vessels to reach the kidneys and then delivers ultrasound or radiofrequency energy. Those waves travel through the kidney’s arteries to selectively target the surrounding veins, as the entire process is very quick and takes only an hour to complete.
Although it is already in use in several other countries — a major U.S. trial of the kidney strain failed nearly a decade ago — prompting changes before researchers tried it again. In November 2023, the FDA approved two catheter systems from Recor Medical and Medtronic.
Although it is not a cure, Many patients with kidney failure benefit fromAs studies show, blood pressure drops by an average of 8 to 10 points—a modest but likely significant improvement.
The FDA says it considers the procedure safe for carefully selected patients. guidance from American Heart Association Prospective patients and experienced doctors were urged to have a “thoughtful and informed discussion” to decide who is a good candidate.
What is high blood pressure,
High blood pressure or hypertension is described by two numbers: the top, “systolic” pressure, which forces blood to push against the walls of the arteries when pumped by the heart, and the bottom, “diastolic” number, which is the same. Measures. Pressure but between heartbeats.
Normal is less than 120 to less than 80. Blood pressure naturally fluctuates throughout the day, being higher when you are physically active or stressed. But when it stays high — consistently from 130 to 80 or higher, according to the latest guidelines — it hardens the arteries and the heart has to work harder.
Other Ways to reduce blood pressure
Apart from taking medication, there are several lifestyle changes recommended by doctors that help reduce blood pressure levels. Several guidelines urge you to:
- lose weight
- Exercise and work out regularly
- Eat more fresh fruits and seasonal vegetables
- limit sodium intake
- quit smoking and alcohol
- Deal with stress through meditation and yoga
According to doctors, when high blood pressure reaches 140 to 90, you should take medicine. The average patient needs two or three medications, sometimes more, to maintain a healthy life.
