Pericardial Disease - Tubin Flashcards
Pericardium - amt of plasma ultrailtrate
15-50 mL
Pericarditis can be ___ or ____
acute or recurrent
Acute Pericarditis - most common cause
idiopathic
(always say “viral”)
Causes of acute pericarditis (5)
- Radiation
- Neoplasm (primary, met, or paraneo)
- Trauma
- AI
- Metabolic (Hyperthyroid, Uremia)
In trauma-induced pericarditis, inflammation in the chest will be accompanied by
effusion
Infecirious causes of pericarditis
Viral = Cox AB, Echo, mumps, adeno, HIV
Bacterial = TB, Pneumococcus, strep, staph, legionella
Fungal = histo, coccidio, candida, blasto
Infectious pericarditis rarely caused by
syphillis
____ pericarditis d/t TB
Purulent
(PICTURE)
Pericardial effusion can cause partial _________
collapse of atria
Cardiac causes of Pericard.
Early infarction
late post cardiac injury (dresslers)
Myocarditis
Dissecting aortic aneurysm
Dressler’s syndrome =
late post cardiac injury
Difficult to tell _______ with echo
nature of effusion
Unstable pericardial effusion - what not to do
immediately drain- have to rule out aortic dissection because if present, you’ve just opened up a space for blood to enter
Blood clots forming in P. effus. may appea ____ on echo
strand-like
Drug induced pericarditis caused by…
Procainamide
Isoniazid
Hydralazine
Usually fluid is ______
Look for what?
Sometimes you’ll see ____ in bact. infection
serous
bacterial or tumor cells
Purulent pericarditis – need aggressive Tx
Fluid in PEff may…
resolve or form adhesions
Clinical features of pericarditis
- CHEST PAIN (main)
- Friction rub
- ECG changes
- Pericrdial effusion
Friction rub is
3 component rub
Best diagnostic tool for acute pericarditis
ECG
Chief complaint for pericarditis
Chest pain unrelated to exertion
(nonspecific complaints = Fatigue, dyspnea, malaise, fever)
Differentiate from MI in complaint
MI doesn’t tend to have many preceding symptoms
Chest pain is present in ____
95% of cases
more comon with infection, less common with uremic or rheum.
Chest pain locaiton
anterior chest wall
Chest pain description
Better/worse when…
Sudden onset
Sharp, pleuritic in nature
- Worse when laying flat, inspiration, or coughing,
- Better when seated or leaning forward.
Rub is d/t
friction between visceral and parietal layers of pericardium
3 parts of rub
First == systole
Second = ventricular diastole
Third = atrial systole
Rub description
triphasic (50-60%)
Biphasic (30%)
scratchy/leathery sound
Eval for acute (8)
- History, exam, ECG
- ESR, CBC, chem
- Troponin
- CXR
- Echo (if suspected effusion)
- NO viral studies
- AI serologies
- Pericardiocentesis
CXR in acute pericarditis is…
usually normal
When do you do an echo with acute pericarditis
if suspected concurrent effusion
