So in summary:
• The definition for atherosclerosis is:
This is a broad term that's used for artery
wall obstruction, vessel tightening due to
development of atherosclerotic plaques, which
are the result of a number of risk factors
that allow injury to the artery and for LDL
cholesterol to get in under the artery and
to start a whole inflammatory process that
basically gets going and just builds on itself.
• The diagnosis in the leg is from intermittent
claudication using the Edinburgh Questionnaire
and ankle–brachial index or ultrasound.
• Of course, there can also be peripheral
vascular disease in the brain, and we're going
to talk about that: damage in the… atherosclerosis
in the carotid artery that leads to blood
clots or pieces of cholesterol going to the
brain, causing strokes.
• Treatment, of course, is lifestyle changes,
medication, discontinuation of smoking, and
hopefully, not getting to angioplasty or surgery
(but in many cases, that's necessary).
• And with respect to prevention, it is
particularly important to maintain the lifestyle
changes that we've been talking about throughout
this lecture in order to control and prevent
the atherosclerotic process.
