Conversely, patients with unexplained new onset cardiomegaly should always be worked up for acute pericarditis. [citation needed] An echocardiogram is typically normal in acute pericarditis but can reveal pericardial effusion, the presence of which supports the diagnosis, although its absence does not exclude the diagnosis. [citation needed]
The onset of purulent pericarditis is usually acute, with most individuals presenting to a medical facility approximately 3 days following the onset of symptoms. [4] As a subtype of pericarditis, purulent pericarditis often presents with substernal chest pain that is exacerbated by deep breathing and lying in the supine position. [5]
In this case, the patient is experiencing post-myocardial infarction pericarditis (PIP), which is characterized by chest pain, low-grade fever, and specific findings on physical examination and electrocardiogram. Aspirin is the drug of choice for PIP and is usually already prescribed for secondary prevention following a myocardial infarction.
Constrictive pericarditis is a condition characterized by a thickened, fibrotic pericardium, limiting the heart's ability to function normally. [1] In many cases, the condition continues to be difficult to diagnose and therefore benefits from a good understanding of the underlying cause.
The disease consists of persistent low-grade fever, chest pain (usually pleuritic), pericarditis (usually evidenced by a pericardial friction rub, chest pain worsening when recumbent, and diffuse ST elevation with PR segment depression), and/or pericardial effusion. The symptoms tend to occur 2–3 weeks after myocardial infarction but can also ...
Myopericarditis is a combination of both myocarditis and pericarditis appearing in a single individual, namely inflammation of both the pericardium and the heart muscle. It can involve the presence of fluid in the heart .
Uremic pericarditis is associated with azotemia, and occurs in about 6-10% of kidney failure patients. BUN is normally >60 mg/dL (normal is 7–20 mg/dL). However, the degree of pericarditis does not correlate with the degree of serum BUN or creatinine elevation. The pathogenesis is poorly understood. [2]
Tuberculous pericarditis is a form of pericarditis. It is a condition in which the pericardium surrounding the heart is infected by the bacterial species Mycobacterium tuberculosis . [ 1 ] Tuberculous pericarditis accounts for a significant percentage of presentations of tuberculosis worldwide. [ 2 ]
