Acute pericarditis is the inflammation of the pericardium (1,2).
Acute pericarditis is diagnosed with presence of 2 or more of the following (3):
- sharp, pleuritic chest pain that worsens when supine (≈90%); new widespread electrocardiographic ST-segment elevation and PR depression (≈25%-50%);
- a new or increased pericardial effusion that is most often small (≈60%); or
- a pericardial friction rub (<30%)
At least one in four patients are at risk of recurrence.
Principles of management:
- non-steroidal anti-inflammatory drugs (NSAIDs) remain the cornerstone of treatment
- addition of 3 months of colchicine can more than halve the risk of recurrence (number needed to treat = four) (1)
- evidence shows that in patients with first attack of pericarditis associated with myocardial involvement, colchicine was safe and efficacious for the reduction of recurrences (2)
- low-dose steroids can be helpful second-line agents for managing recurrences as adjuncts to NSAIDs and colchicine but should not be used as first-line agents
With a first recurrence of pericarditis, colchicine should be continued for at least 6 months (3)
- corticosteroids are often used if pericarditis does not improve with NSAIDs and colchicine
- in certain patients with multiple recurrences, which can occur for several years, interleukin 1 (IL-1) blockers have demonstrated efficacy and may be preferred to corticosteroids
