A

2 Ruptures in ATL

  1. Cardiac rupture (day 5 post MI)
  2. Aortic dissection rupture
  3. Trauma
  4. Anticoagulation
  5. Leukemia

Q

List the types of pericarditis

A
  1. Serous
  2. Fibrinous
  3. Purulent
  4. Hemorrhagic
  5. Constrictive- “does not deserve the name”
17
Q

In this type of pericarditis, the pericardium has a smooth surface, scant neutrophils, lymphocytes, & macrophages. The fluid has a low protein content

A

Serous pericarditis

18
Q

SHAGGY, dry, rough pericardial surface with many neutrophils, lymphocytes, and macrophages

A

Fibrinous pericarditis

19
Q

Red granular surface coated with PUS

A

Purulent pericarditis.. remember purulent exudate!

20
Q

Any pericarditis where blood is involved

A

Hemorrhagic pericarditis

21
Q

Most common type of clinical pericarditis is acute “idiopathic” pericarditis, but it is usually caused by?

A

Virus: Echovirus or Coxsackie virus (haha)

22
Q

A patient comes in with chest pain. The pain goes away when they sit down and lean their torso forward. What diagnosis comes to mind?

A

Acute pericarditis

23
Q

You listen to the hunched over patient’s heart. You hear a friction rub. Do you feel better about your differential of acute pericarditis?

A

Yes you do! Pericardial friction rubs are a pretty specific sign of acute pericarditis

24
Q

A patient with pericarditis has elevated troponin I levels. What do dis mean?

A

Myopericarditis.. The myocardium is being destroyed and is releasing its enzymes (troponin I)

25
You need 2 out of 4 of these findings to diagnose acute pericarditis
1. Typical chest pain 2. Pericardial friction rub 3. "Suggestive" changes on ECG (ST elevation, PR segment elevation) 4. Pericardial effusion
26
Acute pericarditis due to pyogenic bacteria is rare with purulent exudate. What bugs typically cause it?
S. aureus, strep pneumoniae
27
Autoimmune pericarditis is strongly associated with what two autoimmune diseases?
1. Lupus | 2. Rheumatoid arthritis
28
This pericarditis is when the heart is "encased" in fibrous tissue, so that it is not allowed to dilate or hypertrophy.
Constrictive pericarditis
29
How do you treat constrictive pericarditis?
Strip it! Surgically
