一名43 歲男性，有肝硬化病史及長期喝酒習慣，此次因右前臂遭狗隻咬傷併全身倦怠 至急診求診，診斷為嚴重敗血症入駐內科加護中心，住院過程中因發生胸悶及冒冷汗症狀且 併有心肌脢酵素異常，而緊急安排心導管檢查術，檢查結果並未發現有任何冠狀動脈異常狀 況，但住院期間病人偶發有類似冠心症之症狀，直至血液培養結果證實為多殺性巴氏桿菌且 接受適當抗生素治療，病患胸悶症狀明顯緩解。據推測此症狀可能為多殺性巴氏桿菌分泌之 毒素直接影響心肌細胞收縮，致使病患因遭受該菌感染而產生類似急性冠心症病症。

Pasteurella multocida is found in the oral cavity and gastrointestinal tracts of domestic livestock, pets, and wild animals. It is uncommon in humans, but is associated with animal bites and scratches, and can serve as an opportunistic pathogen. Although infection in humans is rare; infected individuals may display symptoms of septicemia, septic arthritis, and pneumonia. We report the case of a cirrhotic patient, who was bitten by a dog and presented with septicemia, disseminated intravascular coagulation, and bleeding. He had symptoms of intermittent chest tightness with elevated cardiac enzymes levels under stable hemodynamically and was suspected to have acute coronary syndrome on hospitalization. Coronary artery angiography showed no abnormality. However, the above symptoms of the patient were relieved after administration of antibiotics. P. multocida septicemia mimicking acute coronary syndrome was highly suspected.
