Acute Myocarditis Caused by Francisella tularensis: a Case Report

Abstract Myocarditis is an inflammatory disease of the myocardium with either focal or diffuse involvement and usually gives rise to chest pain, dyspnea, palpitations, fatigue. In severe cases, arrythmias, syncope, cardiogenic shock may occur. Acute myocarditis most commonly caused by a variety viruses cardiotropic properties. Rare causes include bacterial infections. We, herein, describe case acute intracellular bacterium Francisella tularensis. A young previously healthy male in Northern Sweden was referred emergency department due intense upper-chest pain dyspnea. ECG exhibited minimal ST-segment elevations laboratory parameters revealed pathological levels high-sensitivity cardiac troponin C-reactive protein. Radiological imaging showed increased metabolism enlarged lymph nodes signs that could be compatible left ventricular heart. The combination believed tularensis , endemic Sweden, verified positive serology. patient full recovery after antimicrobial treatment. As this fifth published associated tularensis, we suggest considering tularemia tularemia-endemic area.
