peripheral artery disease
Let an agent explain peripheral artery disease in general terms from cardiovascular guidelines, describe symptoms, diagnosis and treatment, route urgent limb-threatening presentations to emergency care, and route personal questions to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain peripheral artery disease in general terms from cardiovascular guidelines, describe symptoms, diagnosis and treatment, route urgent limb-threatening presentations to emergency care, and route personal questions to clinicians.
A circulatory condition in which narrowed or blocked arteries, usually from atherosclerosis, reduce blood flow to the limbs, most often the legs, causing leg pain on walking, and in severe cases critical limb ischemia with rest pain, ulcers and gangrene, including aortoiliac occlusive disease and related arterial occlusions such as carotid artery occlusion, and rare inherited forms; peripheral artery disease shares risk factors with heart disease and is treated with risk factor control, exercise, medication and revascularisation.
What it is for: Not applicable; a disease.
It can be explain the disease; relay symptoms and diagnosis; relay treatment approaches; route urgent and personal questions.
Distinguishing features
Atherosclerotic cause
Claudication symptom
Ankle-brachial index
Limb threat when severe
What it looks like
Not a visible object; in advanced cases cool, pale limbs with ulcers.
Physical character
global prevalence: about 230 million people - estimates
ankle-brachial index threshold: 0.9 or below ratio - diagnostic
How it is recognised
Narrowed limb arteries from atherosclerosis
Intermittent claudication, critical limb ischemia, aortoiliac occlusive disease
Venous disease affects veins; neuropathy causes different leg symptoms; carotid disease affects the brain
