Q

What term is this?

A buildup of lipids, smooth muscle cells, connective tissue, and debris that forms at the site of injury to an artery.

A

Plaque

17
Q

What is this term?

Risk factors that have been conclusively shown to have a strong association with a certain disease.

A

Primary Risk Factors.

Primary risk factors for coronary artery disease include smoking, hypertension, high blood lipid levels, obesity, and physical inactivity.

18
Q

What term is this?

A form of valvular heart disease involving a streptococcal infection that has caused acute rheumatic fever, typically in children between ages 5 and 15.

A

Rheumatic Heart Disease

19
Q

What term is this?

A predisposing factor statistically linked to the development of a disease, such as coronary artery disease.

A

Risk Factor

20
Q

What term is this?

A cerebral vascular accident, a condition in which blood supply to some part of the brain is impaired, typically caused by infarction or hemorrhage, so that the tissue is damaged.

A

Stroke

21
Q

What term is this?

A disease involving one or more of the heart valves. Rheumatic heart disease is one example.

A

Valvular Heart Disease

22
Q

What term is this?

The acronym for a substance released by blood platelets that promotes the migration of smooth muscle cells from the media of an artery into the intima.

A

PDGF

Platelet-Derived Growth Factor

They promote the migration of smooth muscle cells and they promote the GROWTH of smooth muscle cells.

23
Q

What is this term?

A condition that involves loss of elasticity, thickening, and hardening of the arteries.

A

Aterioscleosis

24
Q

What is this term?

Changes in the lining of the arteries and plaque accumulation, leading to progressive narrowing of the arteries.

A

Atherosclerosis

25
Q

What do LDL’s do?

A

They deposit cholesterol in the arterial wall.

26
Q

What do HDL’s do?

A

They remove cholesterol from the arterial wall and transport it to the liver to be metabolized.

27
Q

What results from a myocardial infarction?

A

Necrosis -> tissue death

28
Q

What are the two categories of stroke?

A

Ischemic Strokes and Hemorrhagic Strokes

29
Q

An ischemic stroke can occur from an obstruction in two possible causes, what are they?

A
  1. Cerebral Thrombosis (the most common)- where a thrombus (clot) forms in a cerebral vessel
  2. Cerebral Embolism- in which an embolus breaks loose from another site in the body and lodges in a cerebral artery.
30
Q

There are two types of hemorrhagic strokes, what are they?

A
  1. Intracerebral Hemorrhage- in which one of the cerebral arteries ruptures in the brain
  2. Subarachnoid Hemorrhage- in which one of the brain’s surface vessels ruptures, dumping blood into the space between the brain and the skull.
31
Q

A stroke on the right side of the brain would have what effect?

A
  1. Vision Problems
  2. Quick inquisitive behavioral style
  3. Paralysis on the left side of the body
  4. Memory Loss
32
Q

A stroke on the left side of the brain would have what effect?

A
  1. Speech and Language Problems
  2. Slow, Cautious Behavioral Style
  3. Paralysis on the right side of the body
  4. Memory loss
33
Q

What two diseases are included within peripheral vascular disease?

A
  1. Varicose veins

2. Phlebitis

34
Q

What is Varicose Veins?

A

Varicose veins result from incompetency of the valves in the veins, allowing blood to back up in the veins and causing them to become enlarged, tortuous, and painful.

35
Q

What is Phlebitis?

A

It is inflammation of a vein.

36
Q

What is a form of valvular heart disease?

A

Rheumatic heart disease.

37
Q

What disease is considered to be an inflammatory disease?

A

Atherosclerosis
