1
Q

Inflammation of pericardium by:

viral infection

thoracic trauma

myocardial infarction

tuberculosis

malignancy

autoimmune conditions

A

Pericarditis

2
Q

What is Pericardial effusion?

A

Where fluid accumulates in space between pericardial sac and heart; swollen tissue creates friction (serous, purulent (bacteria), serous sanguneous)

3
Q

Inflammation of the pericardium?

A

Pericarditis

4
Q

What does the pericardium do for the heart?

A

Is the sac that surrounds, protects, and supports the heart.

5
Q

What triggers pericarditis (most common)?

A
  • viral infections (usually after a respiratory infection) but may also result from other infections.
  • thoracic trauma (e.g., surgery, radiation, accidents)
  • myocardial infarction
  • malignancy
  • tuberculosis
  • uremia
6
Q

What autoimmune conditions trigger pericarditis?

A
  • systemic lupus erythematosus
  • rheumatoid arthritis
  • scleroderma
7
Q

In this inflammatory process (pericarditis) where does fluid shift?

A

From the capillaries to the space between the pericardial sac and the heart.

8
Q

What types of fluid result from pericarditis?

A
  • serous
  • purulent
  • serosanguineous
  • hemorrhagic
9
Q

Serous fluid results from?

A

heart failure

10
Q

Purulent fluid results from?

A

infections

11
Q

Serosanguineous fluid results from?

A
  • neoplasms - uremia
12
Q

Hemorrhagic fluid results from?

A
  • aneurysms - trauma
13
Q

The fluid that can accumulate quickly or slowly in the pericardial cavity?

A

pericardial effusion

14
Q

The fluid that accumulates in the pericardial cavity can progress to life-threatening (what)?

A

cardiac tamponade

15
Q

Fluid that accumulates in the pericardial cavity to the point that compresses the heart (is called)?

A

cardiac tamponade

16
Q

The compression of the heart that occurs during cardiac tamponade prevents?

A

the heart from stretching and filling during diastole.

17
Q

The prevention of the heart from stretching and filling during diastole results in (during cardiac tamponade)?

A

Decreased Cardiac Output

18
Q

During cardiac tamponade what happens because of the decreased cardiac output?

A

Arterial pressures then fall

19
Q

During cardiac tamponade, what happens because of the accumulation of blood within the systemic circulation?

A

venous pressure rises

20
Q

During cardiac tamponade, the pulse pressure narrows?

A

because of the arterial and venous changes.

21
Q

During cardiac tamponade what causes the heart sounds to be muffled upon auscultation?

A

excess fluid drowns out the sound.

22
Q

In what phase of cardiac tamponade present much like cardiogenic shock?

A

Acute cardiac tamponade

23
Q

Cardiogenic shock presents with what symptoms?

A

Hypotension Jugular vein distention (JVD) Muffled heart sounds

24
Q

Acute cardiac tamponade presents much like cardiogenic shock (what symptoms)?

A

Hypotension Jugular vein distention (JVD) Muffled heart sounds (symptoms referred to as Beck triad)

25
Q

What are the symptoms referred to as Beck triad?

A

Hypotension Jugular vein distention (JVD) Muffled heart sounds

26
Q

What can result from cardiac tamponade?

A
  • Heart failure - cardiogenic shock - death
27
Q

Manifestations of Cardiac Tamponade are?

A
  • Falling Arterial Pressures
  • Rising Venous Pressures
  • Narrowing Pulse Pressures
  • Muffled Heart Sounds
