Background. Pericarditis has a heterogeneous clinical spectrum and rate of relapse. Data on aetiology, real-life treatment strategies, and long-term course from contemporary pericarditis cohorts are lacking. Methods. Pericarditis patients referred to the Cardioimmunology Outpatient Clinic at Padua University Hospital in 2001–2020 were retrospectively included. Kaplan–Meier method was used for recurrence-free survival probability estimation. The appropriateness of treatment was assessed based on the European Society of Cardiology guidelines. Results. One-hundred forty-four patients (57% males, mean age 50 years) followed up for 18 months (IQR 7–45) were included; of those, 52% had acute, 35% recurrent, 8% incessant, and 5% chronic pericarditis; 9% had cardiac tamponade at diagnosis. Time to pericardial effusion resolution was 53 days (IQR 16–124); median medical treatment duration was 87 days (IQR 48–148). Treatment was readjusted following the ESC guidelines for nonsteroidal anti-inflammatory drugs in 29% of the cases, steroids in 12%, and colchicine in 25%. Eleven (8%) patients were treated with anti-IL1 agents. Recurrence-free survival probability was 86% at 1st-year follow-up, and 23 patients (16%) had at least one recurrence, with a mean of two relapses per patient. Compared to patients without recurrences, they had a higher frequency of cardiac tamponade (27% vs. 6%, p = 0.006) and left bundle branch block (14% vs. 1%, p = 0.034). Out of the 144 patients, 5 (3%) were diagnosed as having constrictive pericarditis at first evaluation at our clinic, underwent successful pericardiectomy, and are currently alive and asymptomatic. Conclusions. When treated following a guideline-based approach, pericarditis has a favourable evolution. A relevant quote of cases benefits from the treatment readjustment of previously prescribed medical therapy when not in line with ESC recommendations. Cases relapsing despite treatment readjustment should receive anti-IL1 therapies.
