- Tunica intima =

- Tunica media =

- Tunica exterminate =

- Tunica intima = inner layer

- Tunica media = smooth muscle

- Tunica Externia = outer layer

2

Tunica intima is composed of ________________?

Endothelial cells

3

Tunica externia is composed of ____________________________?

Loose connective tissue

4

Tunica media is composed of ____________________?

Smooth muscle

5

HDL stands for ?

High density lipoprotein

6

LDL stands for ?

Low density lipoprotein

7

________ cholesterol is good?

HDL

8

_______ cholesterol is bad?

LDL

9

Total cholesterol should be ____________ or lower?

200 mg/dL or Lower

10

Medications that end in statins are for what?

Cholesterol

11

What is Atherosclerosis?

Gardening of the arteries

12

Atherosclerosis build up leads to ________________ ?

MI (Myocardial Infarction)

13

Risk factors for Atherosclerosis?

- MAJOR RISK FACTOR = Hypercholesterolemia
- increasing age
- Family history of premature CAD
- Male sex UNTIL women hit menopause

14

________ helps keep LDL low?

Estrogen

15

What is an Aneurysm?

Weakening or outpouching of the vessel wall.

16

What are types of Aneurysms?

- Aortic
- Berry (brain)
- Thoracic
- Abdominal aortic

17

What is the most common type of Aneurysm?

Abdominal aortic

18

What is the BIGGEST cause of Aneurysms?

Hypertension

19

What are the causes of Aneurysms?

- Hypertension
- Congenital defects
- Trauma
- Infections
- Atherosclerosis

20

Aneurysms are _________ and ____________

Acute
Life threatening

21

Causes of Thoracic aneurysms?

- Atherosclerosis
- Marfan syndrome

22

Manifestations of thoracic aneurysms?

- Asymptomatic
- Neck, Back, or substernal pain
- Hoarseness
- Brassy cough
- Dyspnea
- Stridor

** 2 down—> ALL OCCUR IN THE THORACIC REGION**

23

Manifestations of Abdominal aortic aneurysms?

- SEVERE Back pain (NOTHING makes it better)
- Pulsating mass

24

Causes of Abdominal aortic aneurysms?

- Hypertension
- Severe atherosclerosis
- smoking
- genetics 🧬

25

Why do you have to watch/ be able to recognize aneurysms?

Because you don’t know when the aneurysm will rupture!

26

What is Hemiplegia?

One sided chest pain

27

What is syncope?

Passing out due to lack of oxygen to the brain 🧠

28

Why do you want a patient with an aneurysm to be Hypotensive (low BP)?

To keep the aneurysm from rupturing

- Ex: 100 systolic @ the highest

29

Why do you want a patient with an aneurysm to be kept flat / have minimal to no movement?

More movement = increase HR & increase BP = rupture

30

What are diagnostic tests for aneurysms?

- aortic angiography
- Transesophageal echocardiography (TEE)
- CT scan of chest, brain or abdomen
- MRI
