Definition of Angiopathy
Angiopathy: Disease of the blood vessels (arteries,
veins, and capillaries). There are two basic types of angiopathy:
microangiopathy and macroangiopathy.
In microangiopathy, the walls of small blood vessels become
so thick and weak that they bleed, leak protein, and slow
the flow of blood. For example, diabetics may develop
microangiopathy with thickening of capillaries in many
areas including the eye.
In macroangiopathy, fat and blood
clots build up in the large blood vessels, stick to the
vessel walls, and block the flow of blood. Three kinds of
macroangiopathy are coronary artery disease (in the heart),
cerebrovascular disease (in the brain), and peripheral
vascular disease (affecting, for example, vessels in the
legs).
