RESEARCH: An international clinical trial involving patients at the London Chest Hospital could transform the lives of people living with high blood pressure around the world.

The team the Barts Hypertension Clinic is partnering with ROX Medical to test a new device aimed at significantly improving blood pressure levels in patients with resistant hypertension in whom three or more drugs have failed to achieve blood pressure control.

If successful, the treatment could lead to a dramatic reduction in the very high risk of stroke or heart attack that these patients face.

The treatment being trialled at The London Chest Hospital, involves a minimally invasive, catheter-based procedure to place a small coupler between the artery and vein in the upper thigh. The device works by reducing the vascular resistance to blood flow and diverting some arterial blood to the veins.
