==Differentiating Pericarditis from other Conditions==
 
Several conditions, including life threatening conditions such as [[myocardial infarction]], [[aortic dissection]] and [[pulmonary embolism]] produce signs and symptoms that are similar to those produced by pericarditis.

* Pain along the [[trapezius ridge]](s), is very characteristic of pericarditis. The pain of [[myocardial infarction]] tends to involve the anterior precordium with radiation to the left arm.   
 
* Unlike cardiac ischemia, the pain of pericarditis often lasts longer, is sharper and unresponsive to vasodilator therapy.
* (35%) Neoplastic
* The EKG of pericarditis shows [[PR]] segment depression while the EKG of myocardial infarction does not.
* (23%) Autoimmune
* The EKG of pericarditis shows [[ST elevation]] that does not necessarily follow the anatomic distribution of a single coronary artery.
* (21%) Viral - [[adenovirus]], [[enterovirus]], [[cytomegalovirus]], [[influenza virus]], [[hepatitis B]] virus, and [[herpes simplex virus]], etc
* ( 6%) Bacterial (other than tuberculosis)
* ( 6%) [[Uremia]]
* ( 4%) [[Tuberculosis]]
* ( 4%) Idiopathic
* (remaining) trauma, drugs, post-AMI, [[myocarditis]], [[dissecting aortic aneurysm]], [[radiation]]

# '''Infectious:'''
#* Viral: [[Coxsackie B Virus]], [[Echovirus]], [[Adenovirus]] (less commonly: [[Mumps]], [[Influenza]], [[varicella]], [[Hepatitis B]] and [[CMV]]-especially in [[HIV]] patients.) Usually associated with a viral prodrome and acute pericarditis.
#* [[Tuberculosis]]: usually bloody, protein greater than 2.5. Initially mostly [[polymorphonuclear cells]], later [[lymphocytes]], [[monocytes]] and [[plasma cells]].  Usually develops very slowly with significant fibrous reaction.  Initially effusive then becomes constrictive.
#* Purulent: [[Pneumococcus]], [[Streptococcus]] and [[Staphylococcus]] most common.  Also Proteus, [[E.coli]], Psuedomonas, [[Klebsiella]], [[Brucellosis]], [[Salmonella]], [[Neisseria]], [[Haemophilus influenza]], [[Tularemia]], [[Legionella]], preodominantly by hematogenous spread and approximately 20% by contiguous spread.  Usually these patients are quite ill.
#* Fungal: [[Histoplasmosis]], [[Coccidiomycosis]], [[Aspergillus]], [[Blastomycosis]], [[Candida]].
#* Other: [[Toxoplasmosis]], [[Amebiasis]], [[Mycoplasma]], [[Nocardia]], [[Actinomycosis]], [[Echinococcus]], [[Lyme disease]] (usually myopericarditis associated with conduction abnormalities).
# '''Neoplastic:'''
#* Predominantly lung, breast, [[leukemia]], [[lymphomas]] ([[Hodgkins]] and non-Hodgkins).  Less commonly GI malignancies, [[ovarian cancer]], [[sarcoma]]s and [[melanoma]]s, metastic, hematogenous, [[carcinoma]], [[carcinoid]], [[Sipple syndrome]], [[mesothelioma]], [[fibroma]], [[lipoma]] .  Also [[Kaposis sarcoma]] in [[HIV]] positive patients.
# '''Uremic:'''
#* [[Uremic]] pericarditis is seen in up to 20% of uremic patients requiring chronic hemodialysis. The mechanism is unknown.  Most commonly there is a small effusion associated with pain and a [[pericardial friction rub]], but there can be a large effusion and present with [[tamponade]].
# '''Autoimmune:'''
#* [[Systemic Lupus Erythematosus]] or [[SLE]]: Pericarditis usually occurs in the setting of disease flares (systemic symptoms, high erythrocyte sedimentation rate ([[ESR]]) , +ANA, +dsDNA, [[pleural effusion]]s).  Occurs in 20-40% of patients with [[SLE]] during the course of the disease.  Usually the fluid is serous or grossly bloody.  Analysis of the fluid usually reveals a high protein and low glucose content.  Typically [[WBC]] count is less than 10K, and is made up of primarily [[polymorphonuclear cell]]s ([[PMN]]s).   
#* [[Rheumatoid arthritis]] or [[RA]]: Pericarditis can occur without active joint involvement.  Also serous or bloody.  Usually the protein is > 5 mg/dl, and the glucose is low (<45).  The [[WBC]] is high at 20-90K.  Complement is usually low, and the latex fixation test is usually positive.  
#* Other: Acute [[rheumatic fever]], [[scleroderma]], mixed [[connective tissue disease]], [[Wegener's]], [[PAN]].
# '''[[Trauma]]tic:'''
#* After chest trauma, throacic surgery, PCM insertion, [[Valvuloplasty]].  Also from [[esophageal rupture]], pancreatic-pericardial fistula (check amylase), penetrating chest injury, esophogeal perforation, gastric perforation, during catheterization (pacemaker insertion, cathether ablation for [[arrhythmias]], diagnostic, PCI with coronary dissection).
# '''Drugs:'''
#* Usually associated with small effusions.  Common culprits include [[hydralazine]], [[procainamide]], DOH, [[isoniazid]], [[phenylbutazone]], [[dantrolene]], [[doxorubicin]], methylsergide, [[penicillin]].
# '''Hypothyroidism:'''
#* Usually in conjunction with clinically severe [[hypothyroidism]].  Most early case reports associated with [[myxedema]] and patients also had [[ascites]], [[pleural effusion]]s and uveal edema. Often resolves with thyroid replacement therapy.
# '''Other:'''
#* Post-MI ([[Dresslers]]), post-pericardiotomy, [[radiation]], [[dissecting aortic aneurysm]], chylopericardium (from thoracic duct obstruction secondary to tumor, surgical procedure, [[trauma]], [[TB]], congenital).  Also, [[sarcoidosis]], [[amyloidosis]], [[IBD]], [[Whipple's]], [[temporal arteritis]] and [[Behcet syndrome]]).
