Flow-mediated dilation (FMD) is a straightforward, non-invasive technique used to assess how well the endothelium is functioning by looking at how arteries, especially the brachial artery, expand when blood flow increases. When FMD is impaired, it signals endothelial dysfunction, which can be an early warning sign of atherosclerosis and cardiovascular issues, giving us a heads-up before any noticeable changes in the blood vessels take place.

The process involves temporarily stopping blood flow with a cuff and then releasing it to create a rush of blood, leading to arterial dilation. We use ultrasound imaging to capture how the arteries respond. FMD is commonly utilized in both research and clinical settings to evaluate vascular health, keep track of treatment effects, and assess cardiovascular risk, making it a crucial tool for spotting and preventing vascular diseases early on
