What does microvascular mean?
Microvascular is an adjective describing the tiny blood vessels of the body, especially the capillaries and other components of the microcirculation. It is widely used in medicine to distinguish damage or disease in these small vessels from conditions affecting the body's larger arteries. Common examples include microvascular complications of diabetes, microvascular disease, and impaired microvascular perfusion. The term can describe structural changes, impaired blood flow, inflammation, or injury involving small vessels. Because these vessels are responsible for exchanges between blood and tissues, microvascular problems can affect organs such as the eyes, kidneys, nerves, and heart. The word is especially familiar in medical research and clinical discussions, where precise terminology helps distinguish small-vessel conditions from macrovascular disease.
