We treated two men (aged 20 and 33\u2005years) who had myocarditis after black spider bites with leucocytosis and elevated levels of troponin I, creatine kinase and creatine kinase-MB fraction. Both patients had normal results on an ECG, and one patient had abnormal echocardiography with minimal left ventricular wall movement disorder. Both patients were hospitalised in the intensive care unit and treated with intravenous fluids, analgesics, spasmolytic drugs, tetanus prophylaxis and cardiac monitoring. The levels of troponin I, creatine kinase and creatine kinase-MB fraction improved, and the patients were discharged home on the third and fifth hospital day without complications. Myocarditis after a <jats:italic>Latrodectus<\/jats:italic> bite is rare, but may be associated with serious complications. Therefore, in regions endemic with <jats:italic>Latrodectus<\/jats:italic> spiders, prudent treatment of spider bites may include cardiac evaluation and monitoring.<\/jats:p>","DOI":"10.1136\/bcr-2013-008957","type":"journal-article","created":{"date-parts":[[2013,4,8]],"date-time":"2013-04-08T22:33:41Z","timestamp":1365460421000},"page":"bcr2013008957","source":"Crossref","is-referenced-by-count":10,"title":["Reversible myocarditis after spider bite"],"prefix":"10.1136","volume":"2013","author":[{"given":"Hasan","family":"Kara","sequence":"first","affiliation":[{"name":"Department of Emergency Medicine, Faculty of Medicine, Selcuk University, Konya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmet","family":"Ak","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Faculty of Medicine, Selcuk University, Konya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aysegul","family":"Bayir","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Faculty of Medicine, Selcuk University, Konya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmet","family":"Avci","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Selcuk University, Konya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2013,4,8]]},"reference":[{"key":"2025082803262176000_2013.apr08_1.bcr2013008957.1","unstructured":"Boyer LV Binford GJ Degan JA .
