The centipede is an elongated and multi-segmented arthropod with a venom apparatus that consists of modified legs on either side of the body just behind the head. Generally, centipede envenomation causes local tissue swelling, redness, pruritus, swollen and painful lymph nodes, headache, nausea, vomiting and anxiety. Adverse systemic reactions such as acute renal failure, rhabdomyolysis and acute myocardial infarction have been associated with centipede bite. We experienced a case of a 57-year-old man who complained of severe chest pain after a centipede (20 cm in length) bite. The electrocardiogram recorded at the emergency medical center showed ST-T changes in the precordial leads. The levels of cardiac enzyme were not elevated [creatine kinase (CK) 101 U/L (35~172), CK-MB 5.1 U/L (2.3~9.5), troponin I 0.06 ng/mL (0~0.05), troponin T 0.02 ng/mL (0~0.1)]. He had a history of percutaneous coronary intervention in the left circumflex artery under the diagnosis of acute myocardial infarction 4 years ago. The emergency coronary angiogram revealed severe diffuse coronary artery spasm in the left coronary artery, which was improved after intracoronary nitroglycerin injection, and patent previously placed stent in the left circumflex artery was noted. He improved after medical treatment and was discharged on the eleventh day without any remained subjective symptoms.
