Radio Waves Lower Blood Pressure
Overactive kidney nerves may cause the body to retain too much sodium, contributing to high blood pressure. To decommission these nerves, researchers zapped them with radio waves delivered via a catheter. Twelve months after the experimental procedure, study participants’ systolic (top number) blood pressures had dropped an average of 28 mmHg. Bleeding complications and low blood pressure on standing were side effects for a few subjects. People with diabetes are at increased risk for hypertension, which is associated with heart and kidney disease. A variety of medications can tackle this condition, but they don’t work on everyone. For some people, radio waves may be an option.
