Night-Time blood pressure drops may hold key to heart risk

This study looks at how blood pressure and artery stiffness change over 24 hours in people at increased risk for heart disease, especially those with kidney problems. Researchers will monitor 120 participants using a wearable device and collect blood and urine samples. The goal is to understand why some people's blood pressure doesn't drop enough at night, which is linked to higher heart risk, and to guide better timing of medication.
