简介：
Overview
The flow mediated dilation (FMD) test is a non-invasive ultrasound assessment of endothelial function in humans. It has potential implications for predicting future cardiovascular disease and events, though it is subject to various confounding factors.

What is the FMD test?
The FMD test is a non-invasive ultrasound assessment used to evaluate endothelial function in humans.
Why is the FMD test important?
It helps predict future cardiovascular disease and events by assessing vascular health.
What are the requirements for participants before the FMD test?
Participants must abstain from exercise, smoking, high-fat meals, and certain medications for specified durations before the test.
Who performs the FMD test?
The test is typically performed by trained professionals, such as registered cardiovascular stenographers.
What factors can affect the results of the FMD test?
Confounding factors include participant preparation, skill level of the operator, and physiological variations.
How can the FMD test be standardized?
Standardization can be achieved through consistent protocols and training for operators.
