Acute pleuropericarditis

Last edited: 4/22/2026

Overview

Acute pleuropericarditis involves inflammation affecting both the pleura and pericardium, often presenting with chest pain, pericardial friction rub, and pleural effusion. The etiology can be idiopathic, post-cardiac injury, or post-infectious, with evidence suggesting an autoinflammatory rather than autoimmune mechanism 1.

Diagnosis

  • Clinical presentation includes chest pain, dyspnea, and signs of pericardial and pleural involvement.
  • Electrocardiogram (ECG) may show nonspecific changes or pericarditis patterns.
  • Echocardiography is crucial for assessing pericardial effusion and cardiac function.
  • Serum markers like C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are often elevated.
  • Serological analysis helps differentiate idiopathic from autoimmune causes 1.
  • Management

  • First-line treatments: Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain and inflammation control.
  • Adjunctive treatments: Corticosteroids may be considered in refractory cases or severe inflammation 1.
  • Monitoring: Regular echocardiograms to track pericardial effusion resolution.
  • Discontinuation of causative agents: If pleuropericarditis is linked to medication like dantrolene, discontinuation is essential 2.
  • Special Populations

  • No specific guidance provided for pregnancy, pediatrics, or elderly patients in the given abstracts.
  • Comorbidities: Careful monitoring and management of underlying conditions that may trigger pleuropericarditis 1.
  • Key Recommendations

  • Evaluate idiopathic pleuropericarditis patients for autoinflammatory mechanisms rather than autoimmune disease, considering serological markers 1 (Evidence: Moderate).
  • Monitor for recurrent attacks, as a majority of patients experience relapses within the follow-up period 1 (Evidence: Moderate).
  • Consider discontinuation of dantrolene in cases developing pleuropericardial reactions, given the potential association 2 (Evidence: Weak).
