Abstract
Acute pericarditis is an inflammatory disease associated with a non-negligible risk of acute complications and future recurrence. However, the exact incidence of pericarditis recurrence in patients with a first uncomplicated clinical course is unknown. We sought to evaluate the incidence and clinical predictors of recurrence after a first episode of acute uncomplicated pericarditis in a large urban hospital in the United States. We conducted a retrospective review, through electronic health records, to complete a database that includes patients admitted with a first episode of acute pericarditis and selected only those with an uncomplicated course (without in-hospital death, large pericardial effusion [>20 mm] or tamponade, constriction, or incessant pericarditis) at the VCU Medical Center (Richmond, Virginia) from 2009 to 2018. A total of 240 patients met acute pericarditis criteria: of the 240 patients, 164 patients (68%) had an uncomplicated course (median age [interquartile range] in years: 50 [32 to 62], 43% females). The median follow-up time was 186 (19 to 467) days. Pericarditis was idiopathic in 84 patients (51%). Fifteen patients (9%) had at least 1 episode of recurrent pericarditis. Compared with those without recurrence, patients with recurrent pericarditis were younger (37 [25 to 59] vs 51 [34 to 62] years, p = 0.034), had a higher prevalence of subacute/delayed presentation (2 [13%] vs 1 [1%], p = 0.023), and less frequently received colchicine (6 [40%] vs 100 [67%], p = 0.036). At multivariate logistic regression analysis, subacute presentation and younger age remained predictors of recurrence at follow-up. In conclusion, 9% of patients with acute pericarditis experienced a recurrence over a 6-month median follow-up despite an initial uncomplicated course. Younger age and subacute presentation were associated with a significantly increased risk of recurrence.
