Acute Pericarditis Flashcards
(15 cards)
causes of acute pericarditis
-traumatic
-Drug induced
- Infectious Most Common Viral
=coxsackie B virus
or idiopathic ..
-Neoplastic
-Immune/inflammatory
-Metabolic
- Iatrogenic
Symptoms
- Chest pain (can be severe)
- dyspnea (common)
- cough, dysphagia, and hiccups
*❑85% of patients have an audible friction rub
Chest pain characteristics in pericarditis
✓Sudden onset, sharp, and worse with inspiration, cough, and body movements
✓
Pain is typically substernal or localized to left chest
✓May be persistent or wax and wane
❑
✓Classically, pain is positional in nature—worse when patient is supine and relieved with sitting up and leaning forward
friction rub sound characteristics
-High-pitched scratchy or squeaky sound best
-heard at the left lower sternal border
at end-expiration with the patient leaning forward
-not affected by breathing
on ECG
diffuse ST elevation (in all leads
-widespread PR depression
-after several days ST normalize then T wave inversion
-after weeks to months ECG returns normal
on Chest radiography
-Often
normal
in patients
-Pulmonary vascular congestion
(may indicate severe
concomitant myocarditis and heart failure)
on Echocardiography:
-May see effusions
Laboratory studies:
Nonspecific markers of inflammation (leukocytosis,CRP,ESR)
Cardiac enzymes:
May be elevated in patients with
concomitant adjacent myocardial inflammation
diagnosis
based on combination of characteristic chest pain ,ECG findings,friction rub,and/or pericardial effusion
first line treatment
colchicine or NSAIDs or high dose aspirin
aspirin : 2-4 days (high dose )(300-600 mg/day)
NSAIDS: 600-800 mg 3 times per day
for 1-2 weeks
colchicine : 0.5 mg BID for 3 months
purpose of colchicine
*reduce recurrence rate
*enhance response to NSAIDs
colchicine side effect
GI upset
avoid in pericarditis
*anticoagulants : increase risk for pericardial bleeding and tamponade
*steroids : increase risk of relapse
when can we use steroids
only if NSAIDS /aspirin are contraindicated or refractory
**they are second line
** azathioprine/anakinra
**used only for 2-4 days
post cardiac injury syndrome
is a form of pericarditis that is caused due to injury to the myocardium ,treatment like pericarditis
