A new multi-test approach may spot hidden blood vessel damage before symptoms appear

This observational study is testing whether a combination of non-invasive measurements—including blood pressure monitoring, ultrasound, blood and urine tests, and a light-based technique called photoplethysmography—can detect early damage to blood vessels and organs in adults at increased cardiovascular risk. The study will enroll about 1,000 participants and will not assign any treatments. The goal is to see which markers and devices are reliable and whether they can improve early risk assessment and prevention.
