| Popis: | Myocarditis is a rare disease manifestation of acute Q fever caused by infection with Coxiella burnetii, an infectious Gram-negative proteobacteria. C. burnetii has a large animal reservoir and is often transmitted to humans during animal birth. Acute Q fever has a nonspecific disease presentation leading to delayed treatment and potentially worsened clinical outcomes. We describe a case of an otherwise healthy adult man with angina, ST elevations, and positive cardiac troponins—all findings suggestive of acute coronary syndrome. Cardiac catheterization revealed no significant coronary blockages or abnormalities. On echocardiography he was found to have heart failure with reduced ejection fraction. The patient’s social history included several risk factors for Q fever. Serologic testing returned positive for anti-C. burnetii antibodies, and a diagnosis of acute Q fever myocarditis was made. The patient was appropriately treated with a course of doxycycline and clinically improved. |
