Vasculature Conditions Flashcards
define atherosclerosis
a disease of the arteries characterized by the deposition of fatty material on their inner walls
is a thicker or thinner atherosclerotic fibrous cap better for prognosis
thicker (less likely to burst)
PVD basic pathological features
Peripheral vascular disease (PVD) is a blood circulation disorder that causes the blood vessels outside of your heart and brain to narrow, block, or spasm. This can happen in your arteries or veins. PVD typically causes pain and fatigue, often in your legs, and especially during exercise.
what is an arteriovenous malformation an example of?
a congenital vasculature disorder
what impact does Marfan syndrome have on vasculature
the walls of the blood vessels become weak and dilate (stretch).
this often affect the aorta
how can hypertension lead to atherosclerosis
endothelial damage
physiological difference between STEMI and nonSTEMI
STEMI = 'classic' heart attack, extensive damage to heart nonSTEMI = intermediate form of acute coronary syndrome, causes extensive damage to the heart

define ischemia, angina & infarction
ischemia: a condition in which the blood flow (and thus oxygen) is restricted or reduced in a part of the body
angina: Angina (pectoris) is a type of chest pain and the result of myocardial ischemia caused by an imbalance between myocardial blood supply and oxygen demand. a common symptom of coronary artery disease
infarction: tissue death (necrosis) due to inadequate blood supply to the affected area - may be caused by vasoconstriction, obstruction, mechanical compression or rupture. essentially progressed ischemia
what is DVT and what can commonly cause it
a blood clot in a vein, usually the leg
Anything that prevents your blood from flowing or clotting normally can cause a blood clot. The main causes of DVT are damage to a vein from surgery or trauma and inflammation due to infection or injury
what is an aneurysm and why are they dangerous
a weakening of an artery wall that creates a bulge, or distention, of the artery.
Most aneurysms do not show symptoms and are not dangerous. However, at their most severe stage, some can rupture, leading to life-threatening internal bleeding.
what is vasculitis
an autoimmune disease that causes inflammation and narrowing of blood vessels
complications of vasculitis
When your blood vessel becomes weak, it might stretch and bulge (aneurysm). It might also burst open, causing bleeding.
Blood clots may form in a blood vessel, obstructing blood flow.
what is AAA
abdominal aortic aneurysm
what is an atheroma
An atheroma, or atheromatous plaque (“plaque”), is an abnormal accumulation of material in the inner layer of the wall of an artery. The material consists of mostly macrophage cells, or debris, containing lipids, calcium and a variable amount of fibrous connective tissue.
what is a berry aneurysm
A berry aneurysm, which looks like a berry on a narrow stem, is the most common type of brain aneurysm. They make up 90 percent of all brain aneurysms, according to Stanford Health Care. Berry aneurysms tend to appear at the base of the brain where the major blood vessels meet, also known as the Circle of Willis.
