[Acute myocardial infarction after blunt polytrauma -- successful coronary intervention].
Acute myocardial infarction following blunt chest trauma is a well reported but rare finding. Especially in severely injured patients the optimal therapy of the myocardial infarction is not well established, since anticoagulants, platelet aggregation inhibitors or thrombolytics are frequently contraindicated under these conditions. We report a case of a 41-year-old man, who presented with an acute myocardial infarction in combination with a severe polytrauma (multiple rib fractures, hematothorax, pelvic bone fractures, multiple injuries of intestinal organs) after a motorcycle accident with a blunt chest and abdominal trauma. After surgical treatment of the injuries of the bones and the intestinal organs a coronary angiography was immediately performed. The left anterior descending and the circumflex coronary artery were occluded in the mid-portion of the vessels. Coronary recanalization by PTCA and the implantation of coronary stents were successful in both vessels. Despite of a non-optimal blood flow after recanalization and stenting in one vessel (LAD TIMI II flow after recanalization), and a non-optimal accompanying medical therapy, during and after intervention (intravenous heparin starting 8 hours after the coronary intervention and platelet inhibitors starting 4 days after the intervention) the coronary angiogram after 2 months documented both vessels patent without a reocclusion or a restenosis. The case report documents, that in traumatic myocardial infarctions the treating of both, the attending injuries and the myocardial ischemia, is feasible. Early coronary angiography and coronary interventions, with or without stent-implantation, are indicated, even in cases in which an adequate accompanying medical therapy with heparin and platelet inhibitors is contraindicated.
