Suspected Legionella-induced perimyocarditis
in an adult in the absence of pneumonia: a rare clinical entity.
Once categorized with a specific diagnosis, the incidence of evacuation for patients with a cardiovascular diagnosis significantly exceeded the overall 15% evacuation rate for perimyocarditis
(46%), pulmonary embolism (87%), acute coronary syndrome (100%), supraventricular tachycardia (43%), ventricular tachycardia (67%), and atrial fibrillation/flutter (37%).
The final adjudicated diagnoses in patients falsely ruled in for AMI (n = 27) on the basis of the algorithm were acute heart failure (n = 2), stable CAD (n = 1), perimyocarditis
(n = 2), cardiomyopathy (n = 2), pulmonary disease (n = 3), sinus venous thrombosis (n = 2), Wolff-Parkinson- White syndrome (n = 1), atrial fibrillation (n = 2), vasovagal (n = 1), palpitations (n = 1), possible unstable angina (n = 4), unspecified cardiovascular problem (n = 2), and noncardiovascular problem (n = 4).
Sands, Jr, Pericarditis and perimyocarditis
associated with active Mycoplasma pneumoniae infections.
Simultaneous primary infection with HIV and CMV leading to severe pancytopenia, hepatitis, nephritis, perimyocarditis
, myositis, and alopecia totalis.
Also, several patients with perimyocarditis
associated with R.
, tachyarrhythmias) and noncardiac symptoms.
helvetica was linked to acute perimyocarditis
, unexplained febrile illness, and sarcoidosis in humans in Europe (3-5).
helvetica, was first isolated in Switzerland in 1979 and was implicated in perimyocarditis
and nonspecific febrile disease in humans (2-5).
should be considered if MI has been ruled out in a patient with dyspnea and chest discomfort, especially with a history of recent viral illness (50).
However, in 1999 it was implicated in fatal perimyocarditis
in patients in Sweden (31).
An example is Rickettsia helvetica, which was originally isolated in 1979 from Ixodes ricinus but was shown to have pathologic relevance only in 1999, when it was associated with fatal perimyocarditis
in two Swedish men (3).
