Hypertension Is Controlled By A Rice-Grain Sized Carotid, Finds Study

A new study has found that the blood pressure level in the body is controlled by the carotid body – a small organ which is the size of a grain of rice located between two major arteries that feed the brain with blood.

Researchers at the University of Bristol have found that removing one carotid body from some patients with high blood pressure can provide immediate and sustained fall in blood pressure. This indicates that the carotid bodies appear to be a cause of high blood pressure.

“The falls in blood pressure are impressive-more than pharmacological medication-and demonstrate the potential for targeting the carotid body to treat hypertension,” said Angus Nightingale, researcher at the University of Bristol, England.

The World Health Organization (WHO) has also recognized hypertension as the most crucial risk the human health which in another way can cause sudden death of the patient.

The reports of this clinical trial also stated that the carotid bodies play the key role in raising the carotid body activity among patients, and these patients face difficulties in inhaling and produced inflated breathing responses when the oxygen level was lesser in their blood.

However, the researchers have also cleared that, this new surgical way to deal with hypertension was effective, but it would not be beneficial for long-term treatment and healing.

“Although this surgical approach to controlling high blood pressure was successful, we don’t think this will be the solution in the long term. We now need to find a drug that dampens down an overactive carotid body and resets the blood pressure thermostat to a normal level,” Nightingale added.

The research study has been published recently in the Journal of American College of Cardiology: Basic to Translational Science.
