Background
Causes:
- idiopathic
- infectious, including AIDS related
- malignancy: heme, lung, breast
- uremia
- post radiation
- connective tissue dz
- drugs: procainamide, hydralaine, methyldopa, anticoagulants
- cardiac injury (can see up to weeks later): post MI, trauma, aortic dissection
Diagnosis
- usually sharp pleuritic chest pain, but can be anything
- radiates to chest, back, trapezius ridge
- diminish with sitting up/lean forward
- SOB, esp if concommitant pleural effusion
- hypotension/extremis if tamponade
Workup
EKG is virtually diagnostic
- less reliable in post MI patients and others with baseline EKG abnormalities
- if pt. has early repol.confounding interpretation, check (ST elev)/(T height) in V6; if >0.25 likely pericarditis
EKG progression:
- global concave up ST elev, +/- PR depression
- ST to baseline, big T's, PR dep
- T wave flatten then inversion
- return to baseline EKG
CXR, WBC, ESR, CK-MB, TN all nonspecific.
Echo will show NL wall motion
- also useful to monitor progress
Friction rub
Differential Diagnosis
MI is the big confounder
| MI | Pericarditis |
| no fever |
fever pain varries w/motion |
| focal ST chgs | diffuse ST elev |
| reciprocal chgs | no reciprocal chgs |
| Q waves | no Q wave |
| +/- pulm edema | clear lungs |
| wall motion abn | nl wall motion |
also on DDx:
CHF, PE, PTX, aortic dissection, pneumomediastinum, pleuritis
Treatment
- Mostly supportive
- NSAIDS for viral/idiopathic
- Recurrent - colchicine
- Uremic - dialysis
- "buy time" with fluid boluses
- Tamponade --> pericardiocentesis
(See Procedures: Pericardiocentesis)
Disposition
- Most need admission, but if young and healthy can echo, and D/C with close f/u
Risk Stratification
HIGH RISK (admit)
- Subacute sx (several dys-wks)
- Fever >100.4
- Evidence of tamponade
- Large effusion (>20mm)
- Immunosupressed
- On anticoagulant
- Acute trauma
- Failure to respond to NSAID Rx (>7dy)
Complications
Tamponade/Effusion-see Pericardial Effusion and Tamponade
Recurrence
- usually weeks to months after initial episode
- management is same
=Contrictive Pericarditis
- restrictive picture with pericardial calcific on CXR and thicken on ECHO
- Rx window
