Overview
The management of pericarditis depends on whether the patient has an uncomplicated vs. complicated disease course. Uncomplicated pericarditis is generally treated with non-steroidal anti-inflammatory drugs, such as Ibuprofen in cases of either viral or idiopathic pericarditis, and Aspirin in cases of post-MI pericarditis. Pericarditis complicated with either effusion or cardiac tamponade is generally treated with urgent pericardiocentesis in the case of cardiac tamponade, antibiotics in the case of purulent pericardial effusion, and either steroids or colchicine among patients with recurrent or refractory disease.
Management of Uncomplicated Pericarditis
Patients with uncomplicated acute pericarditis can generally be treated and followed up in an outpatient clinic. The treatment of viral or idiopathic pericarditis is with non-steroidal anti-inflammatory drugs. Patients should be observed for side effects since NSAIDs are known to affect the GI mucosa. If the underlying cause of pericarditis is something other than a viral cause, the specific etiology should be treated.
Non-steroidal Anti-inflammatory Drugs (NSAIDs)
NSAIDs are the mainstay of therapy for uncomplicated pericarditis (viral or idiopathic pericarditis). The goal of therapy is to reduce pain and inflammation. While symptoms are improved by NSAIDs, the duration of the episode may not be reduced. The preferred NSAID is ibuprofen which has a large range of doses that can be titrated to the patient's tolerance.[1] Depending on the severity of symptoms, the dosing is between 300-800 mg every 6-8 hours for days or weeks as needed. In order to minimize a recurrence of symptoms, a slow tapering of the NSAID dose may be required. As with all NSAID use, GI prophylaxis should be strongly recommended. Gastroprotection with misoprostol (600 to 800 g/day) or omeprazole (20 mg/day) is highly recommended.[2] The gastroprotection recommendation is based on several studies have evaluated factors that place patients at increased risk of gastroduodenal toxicity from NSAIDs.[3]
The American College of Gastroenterology identified the five most important risk factors for gastroduodenal toxicity:
- Age 60 years (relative risk [RR] 5.52)
- History of an adverse gastroduodenal event (RR 4.76)
- High-dosage NSAIDs (more than twice normal; RR 10.1)
- Concurrent use of glucocorticoids (RR 4.4)
- Concurrent use of anticoagulants (RR 12.7).[4]
Patients with several risk factors are at highest risk of NSAID-induced gastroduodenal toxicity.
Aspirin Therapy
An alternative therapy is aspirin 800 mg every 6-8 hours.[5]
Post-MI Pericarditis
In pericarditis following acute myocardial infarction, NSAIDs other than aspirin should be avoided since they can impair scar formation.
Failure to Respond to a Week of Traditional Therapy
Failure to respond to NSAIDs within one week (as indicated by persistence of fever, a worsening of symptoms such as chest pain, the development of a new pericardial effusion), likely indicates that the underlying cause may not be viral or idiopathic in nature. These patients may require re-evaluation, observation, and more aggressive therapy as described in the next section.
Colchicine
In the European guidelines, colchicine carries a class IIa recommendation for the treatment of an initial episode of pericarditis along with an NSAID. The dose is 0.6 mg bid for 3 months. It should be noted that a long term treatment of colchicine for several weeks or months should be considered, even after disappearance of effusion.[6] [7]
The rate of recurrence after an initial episode is lowered with colchicine therapy by approximately 50% - from 26% to 14% (see Forest plot).[8]
For example, in a multicenter, double-blind trial, the use of colchicine at a dose of 0.5 mg twice daily for 3 months for patients weighing >70 kg or 0.5 mg once daily for patients weighing ≤70 kg in acute pericarditis, when added to conventional antiinflammatory therapy with aspirin or ibuprofen, significantly reduced the rate of symptom persistence at 72 hours (19.2% vs. 40.0%, P=0.001), the number of recurrences per patient (0.21 vs. 0.52, P = 0.001), the hospitalization rate (5.0% vs. 14.2%, P = 0.02), and the remission rate at 1 week (85.0% vs. 58.3%, P<0.001), as compared with placebo.[9]
Steroids
Steroids are not used to treat an initial episode of pericarditis. They provide rapid relief in pain, but are associated with a high rate of recurrence.
Identification of High Risk or Complicated Pericarditis
Patients at high risk of developing complications of pericarditis may required admission to an inpatient service for careful observation for hemodynamic compromise. High risk patients include those with:[5]
- Acute onset
- High fever (> 100.4°F) and leukocytosis
- Development of cardiac tamponade
- Large pericardial effusion (echo-free space > 20 mm) resistant to NSAID treatment
- Immunocompromised status
- History of oral anticoagulation therapy
- Pericarditis secondary to acute trauma
- Failure to respond to seven days of NSAID treatment
Management of Complicated Pericarditis
- Pericardiocentesis may be required to relieve a large effusion or to treat cardiac tamponade.
- Antibiotics are required to manage an underlying bacterial infection or a purulent pericarditis.[10]
|
- † Immediate pericardial fluid removal for hemodynamic compromise
- ‡ Modify regimen and narrow coverage based on results of culture and susceptibility tests.
- Antifungals are required to manage an underlying fungal infection, (Histoplasmosis is the most common fungal cause pericarditis associated with histoplasmosis mediastinitis.[11]
|
- Steroids may be required in recurrent refractory cases or in patients with autoimmune disease.
- Colchicine may be required in patients with recurrent or refractory disease (see below).
- Surgery may be required in the presence of recurrent effusion or constrictive pericarditis.
Management of Cardiac Tamponade and Large Pericardial Effusion
Pericardiocentesis is an invasive procedure in which the pericardial fluid is drained through a needle. A pericardial window is a surgical procedure to drain fluid form the pericardium. Indications for a pericardiocentesis or a pericardial window include the following:[1]
- Cardiac tamponade
- Large, persistent, symptomatic pericardial effusion
- For diagnostic purposes, if there is suspected purulent, tuberculosis, or neoplastic pericarditis.
Management of Recurrent Pericarditis
- Colchicine can be used alone or in conjunction with NSAIDs in prevention and treatment of recurrent pericarditis. Treatment involves an NSAID plus colchicine 2 mg on first day followed by 1 mg daily[5] for three months.[12][13][14] A multicenter, double-blind, randomized trial, showed colchicine at a dose of 0.5 mg twice daily for 3 months for patients weighing >70 kg or 0.5 mg once daily for patients weighing ≤70 kg, in addition to conventional antiinflammatory therapy with aspirin or ibuprofen, reduced the number of recurrences per patient (0.21 vs. 0.52, P = 0.001), as compared with placebo.[9]
- Corticosteroids are usually used in those cases that are clearly refractory to NSAIDs and colchicine and a specific cause has not been found. Systemic corticosteroids are usually reserved for those with autoimmune disease. Steroids are sometimes used in post-operative pericarditis as well.
- Pericardiectomy can be performed if the patient is refractory to medical therapy as a last resort. Most patients will respond to 2 to 3 months of aggressive medical therapy.
