Overview
Non-specific markers of inflammation are generally elevated in pericarditis. These include the leukocyte count, C-reactive protein, and ESR. The cardiac troponin is elevated if there is an injury to the underlying myocardium, a condition termed as myopericarditis. Diagnostic pericardiocentesis and biopsy help in identifying an underlying infectious or malignant process.
Inflammatory Markers
The following inflammatory markers are often elevated:
- CBC: Significant leukocytosis may be present.
- C-reactive protein
- Erythrocyte sedimentation rate (ESR)
Cardiac Biomarkers
The following markers of myonecrosis may be elevated if there is involvement of the underlying myocardium:
- Creatine kinase: Acute pericarditis may be associated with a modest increase in serum creatine kinase-MB (CK-MB) depending upon the extent of involvement of the underlying myocardium.[1][2]
- Cardiac troponin-I (cTnI)[3][4]: The troponin can be elevated if there is an underlying myositis, or a myopericarditis. In Europe, patients with pericarditis and an elevated troponin are hospitalized briefly to assure that the patient is stable.
- LDH: Serum LDH may be elevated depending upon the extent of myocardial involvement.
- Serum myoglobin
- SGOT (AST)
Autoimmune Markers
Following autoimmune markers may be checked in patients with recurrent or prolonged pericarditis:
Gallium-67 Imaging
Gallium-67 scanning may help identify inflammatory and leukemic infiltrations.
Diagnostic Pericardiocentesis
Pericardiocentesis is a relatively safe procedure when guided by echocardiography, especially when large free anterior pericardial effusion is present. Pericardial fluid should be aspirated and tested for the presence of malignant cells and tumor markers, particularly in patients with hemorrhagic effusion without preceding trauma.[5] However, hemorrhagic pericarditis in developing countries could be due to tuberculosis. Sensitivity of cytological analysis of pericardial fluid for malignant cells was 67%,[6] 75%,[7] and 92%[8] in different studies with specificity of 100%. Immunohistochemistry can be used to distinguish between the malignant cells and their possible origin.[9][10]
Aspirated fluid can also be used for the following tests:
- Gram staining
- Acid-fast staining
- Microbial culture
Pericardial Biopsy
If the clinical suspicion of malignancy is high, and if the results of cytology testing from the pericardiocentesis are negative, consideration should be given to performing a pericardial biopsy. This can be performed via either a subxiphoid or transthoracic pericardiostomy or alternatively by pericardioscopy. Advantages of pericardioscopy include helping to directly visualize the pericardium as well as helping to collect the biopsy sample. Pericardioscopy has an excellent sensitivity of 97%,[7][11] which compares quite favorably to a blind biopsy which has a low sensitivity of 55-65%.
2015 ESC Guidelines on the Diagnosis and Treatment of Pericarditis (DO NOT EDIT)[12]
Recommendations for the general diagnostic work-up of pericardial diseases
| Class I |
| 1. In all cases of suspected pericardial disease a first diagnostic evaluation is recommended with:
– ECG – transthoracic echocardiography – routine blood tests, including markers of inflammation (i.e., CRP and/or ESR), white blood cell count with differential count, renal function and liver tests and myocardial lesion tests (CK, troponins). 2. CT and/or CMR are recommended as second-level testing for diagnostic workup in pericarditis. 3. Pericardiocentesis or surgical drainage are indicated for cardiac tamponade or suspected bacterial and neoplastic pericarditis. 4. Further testing is indicated in high-risk patients (defined as above) according to the clinical conditions. (Level of Evidence: C)
|
| Class I |
| It is recommended to search for independent predictors of an identifiable and specifically treatable cause of pericarditis (i.e. bacterial, neoplastic, systemic inflammatory diseases). Major factors include:
– fever >38 C – subacute course (symptoms developing over several days or weeks) – large pericardial effusion (diastolic echo-free space >20 mm in width) – failure of Aspirin or NSAIDs (Level of Evidence: B)[13][14]
|
| Class IIb |
| Percutaneous or surgical pericardial biopsy may be considered in selected cases of suspected neoplastic or tuberculous pericarditis. (Level of Evidence: C) |
Recommendations for diagnosis of acute pericarditis
| Class I |
| 1. ECG is recommended in all patients with suspected acute pericarditis.
2. Transthoracic echocardiography is recommended in all patients with suspected acute pericarditis. 3. Chest X-ray is recommended in all patients with suspected acute pericarditis. 4. Assessment of markers of inflammation (i.e. CRP) and myocardial injury (i.e. CK, troponin) is recommended in patients with suspected acute pericarditis. (Level of Evidence: C)
|
Recommendations for the diagnosis and therapy of viral pericarditis
| Class IIa |
| For the definited diagnosis of viral pericarditis, a comprehensive workup of histological, cytological, immunohistological and molecular investigations in pericardial fluid and peri-/epicardial biopsies should be considered. (Level of Evidence: C) |
| Class III |
| 1. Routine viral serology is not recommended, with the possible exception of HIV and HCV.
2. Corticosteroid therapy is not recommended in viral pericarditis. (Level of Evidence: C)
|
Recommendations for the diagnosis of purulent pericarditis
| Class I |
| 1. Urgent pericardiocentesis is recommended for the diagnosis of purulent pericarditis.
2. It is recommended that pericardial fluid be sent for bacterial, fungal and tuberculous studies and blood drawn for cultures. (Level of Evidence: C)
