The recurrence rate appears to be in the range of 15% to 32% after an initial attack. Causes: ◦ ◦ ◦ ◦ ◦ ◦ Idiopathic Infectious: viral (CMV, HIV, Herpes), bacterial, fungal Systemic disease Dressler’s: post MI Trauma Neoplasm Pericarditis can be classified according to the composition of the inflammatory exudate or in other words the composition of the fluid that accumulates around the heart.[1] Types include: serous purulent fibrinous caseous hemorrhagic Post infarction Depending on the time of presentation and duration, pericarditis is divided into "acute“ (more common) and "chronic" forms. Acute pericarditis can occur as a complication of infections, immunologic conditions, or MI Chronic or constrictive pericarditis is a less common Clinical classification of acute vs. chronic: ◦ Acute (<6 weeks) ◦ Subacute (6 weeks to 6 months) ◦ Chronic (>6 months Chest pain characteristic of pericarditis: Substernal or left precordial pleuritic Radiation to trapezius ridge Relieved by sitting up/bending forward Worsened by recumbent position or deep breath May resemble angina/MI but differs in that pain changes with body positions ◦ Other symptoms may be dry cough, fever, fatigue, anxiety ◦ ◦ ◦ ◦ ◦ Due to similarity to myocardial infarction pain, pericarditis can be misdiagnosed as an acute MI solely based on the clinical data therefore extreme suspicion on the part of the diagnostician is required Characteristic/Parameter Pericarditis Myocardial infarction Pain description Sharp, pleuritic, retro-sternal (under the sternum) or left precordial (left chest) pain Crushing, pressure-like, heavy pain. Described as "elephant on the chest." Radiation Pain radiates to the trapezius ridge (to the lowest portion of the Pain radiates to the jaw, or the scapula on the back) or no left or arm, or does not radiate. radiation. Exertion Does not change the pain Can increase the pain Position Pain is worse supine or upon inspiration (breathing in) Not positional Sudden pain, that lasts for hours or sometimes days before a patient comes to the ER Sudden or chronically worsening pain that can come and go in paroxysm or it can last for hours before the patient decides to come to the ER Onset/duration The classic sign of pericarditis is a friction rub auscultated at the left sternal border Other signs include: ◦ ◦ ◦ ◦ positional chest pain Diaphoresis pulsus paradoxus Beck’s triad: which describes three medical signs associated with acute cardiac tamponade, a medical emergency due to fluid accumulation around the heart impairing the heart’s ability to pump blood observed as: Low arterial blood pressure Jugular venous distension Distant and muffled heart sounds (narrowing of pulse pressure may also be observed) ASA/NSAIDS for viral/idiopathic causes Pericardiocentesis for effusion/cardiac tamponade Antibiotics for bacterial infections Steroids in acute pericariditis but may increase risk for recurrence constrictive pericarditis is a late sequela of an inflammatory condition of the pericaridum. The inflammatory condition is usually an infection that involves the pericardium, but it may be after a MI or after heart surgey http://en.wikipedia.org/wiki/Pericarditis http://www.medicinenet.com/pericarditis/article.htm http://www.stjosham.on.ca/media/PatientED/PT/Pericarditis-trh.pdf http://emedicine.medscape.com/article/156951-differential http://www.drugs.com/cg/chronic-pericarditis.html
