A 52-year-old man was admitted to our hospital due to shortness of breath that developed one week after the diagnosis of influenza infection. He had a past history of myocarditis associated with influenza B infection 16 years before the current admission. The patient's left ventricular function showed diffuse hypokinesis with a left ventricular ejection fraction of 28%. Due to the progression of heart failure, the infusion of catecholamines and insertion of an intra-aortic balloon pump were required. The patient was discharged uneventfully on the 23rd hospital day. A significant increase in the serum antibody titer against influenza A virus subtype H3N2 led to a diagnosis of recurrent fulminant influenza myocarditis.
一名52岁男性因流感感染诊断一周后出现呼吸急促而入院。他在本次入院前16年有过与乙型流感感染相关的心肌炎病史。患者左心室功能显示弥漫性运动减弱，左心室射血分数为28%。由于心力衰竭进展，需要输注儿茶酚胺并插入主动脉内球囊泵。患者于住院第23天顺利出院。血清中针对甲型H3N2流感病毒的抗体滴度显著升高，从而诊断为复发性暴发性流感心肌炎。
