Prognostic and Diagnostic Significance of Serum High-Sensitivity C-Reactive Protein Level in Patients with Acute Idiopathic Pericarditis.

Background: The frequency of increased high-sensitivity C-reactive protein (hs-CRP) and the time course of evolution of their levels in patients with acute idiopathic pericarditis (AIP) are not well established.

Objectives: To assess the time course of evolution of hs-CRP levels and the possible clinical significance of maximal hs-CRP levels in patients with AIP.

Methods: We retrospectively reviewed the medical files of 241 patients admitted to the hospital with a diagnosis of AIP between March 2006 and March 2017.

Clinical significance of myocardial involvement in acute idiopathic pericarditis.

Background: Acute idiopathic pericarditis (AIP) is frequently accompanied by myocardial involvement (AIPM). Although in acute myocarditis, the myocardial inflammation can lead to life-threatening complications, the outcome of patients with AIPM has been described as good. It remains unclear if a good prognosis of patients with AIPM reflects mild myocardial involvement or good medical management.
