The document describes an early warning system called AngioDefender for detecting cardiovascular disease risk. AngioDefender uses a non-invasive technique called flow-mediated dilation to measure the health of the endothelium lining blood vessels and assess a person's vascular health and risk of cardiovascular events. It provides results quickly in just 20 minutes and allows patients and doctors to monitor progress and tailor treatment plans to reduce disease risk over time by improving endothelial function.
