Influenza‐associated septic shock accompanied by septic cardiomyopathy that developed in summer and mimicked fulminant myocarditis

Case Fulminant myocarditis (FM) and septic cardiomyopathy (SC) are two different disease entities, and distinction between them is important. A 34‐year‐old man had refractory shock, multiple organ failure, and elevation of cardiogenic markers. Echocardiogram showed tachycardia with extended ST eleva...

Description
Summary:Case Fulminant myocarditis (FM) and septic cardiomyopathy (SC) are two different disease entities, and distinction between them is important. A 34‐year‐old man had refractory shock, multiple organ failure, and elevation of cardiogenic markers. Echocardiogram showed tachycardia with extended ST elevation, and a rapid test for influenza A virus was positive. He was admitted with suspected FM induced by influenza. Outcome Echocardiography showed severe left ventricular dysfunction and dilatation, but no myocardial edema. Inconsistent with FM, a right heart catheter examination showed preserved cardiac output. Therefore, SC was considered and standard therapy for septic shock was initiated. He was stabilized in the first 72 h without mechanical circulatory support. Conclusion Influenza A infection can cause septic shock accompanied by SC. This condition is confusing in the clinical appearance of FM. However, SC shows critically different features of FM, and it might not occur in the epidemic period. In this report, we describe a case in which septic cardiomyopathy due to influenza A infection developed into septic shock in a 34‐year‐old man without a remarkable medical history. Influenza A infection can sometimes cause septic shock accompanied by septic cardiomyopathy.
