DETROIT (AP) -- The Detroit Medical Center and Wayne State University's medical school are enrolling patients in a study that tests a new approach to fighting treatment-resistant high blood pressure.

The university says the chronic condition is a major health threat to 6 million Americans.

The school says the clinical trial will evaluate the safety and effectiveness of this therapy for people with treatment-resistant hypertension.

The university and health system say patients with the disease may be at risk for heart attacks, strokes and other life-threatening cardiovascular disorders triggered by high blood pressure.

The trial will evaluate the safety and effectiveness of a procedure called renal denervation, which aims to deactivate overactive nerves in the renal artery leading to the kidney.
