Anticoagulation and antiplatelet therapy became a cornerstone of the primary treatment strategy in the case of acute coronary syndrome patients which planned to receive medical treatment or percutaneous coronary intervention. The anticoagulation regimen is unfractionated heparins and low molecular weight heparins enoxaparin. Despite of some debates, enoxaparin has replaced unfractionated heparins recently due to its demonstrated advantages. When we encountered acute coronary syndrome patients without contraindication for enoxaparin, it tends to be administered with no hesitation. However, a few patients treated with enoxaparin could be suffered from bleeding complication. Also, in case of bleeding into the retroperitoneal space, the result can be fatal. We report a patient who developed a fatal retroperitoneal hematoma during enoxaparin treatment for acute coronary syndrome.

The enzyme activities of creatine kinase(CK), its isoenzyme MB(CK-MB) and of lactate dehydrogenase isoenzyme 1(LD-1) have been used for years in diagnosing patients with chest pain in order to differentiate patients with acute myocardial infarction(AMI) from non-AMI patients. These methods are easy to perform as automated analyses, but they are not specific for cardiac muscle damage. During the early 90's the situation changed. First, creatine kinase MB mass(CK-MB mass) replaced the measurement of CK-MB activity. Subsequently cardiac-specific proteins, troponin T(cTnT) and troponin I(cTnI) appeared and displacing LS-1 analysis. However troponin concentration in blood increase only from four to six hours after onset of chest pain. Therefore a rapid marker such as myoglobin, fatty acid binding protein or glycogen phosphorylase BB could be used in early diagnosis of AMI. On the other hand, CK-MB isoforms alone may also be useful in rapid diagnosis of cardiac muscle damage. Myoglobin, CK-MB mass, cTnT and cTnI are nowadays wisely used in diagnosing patients with acute chest pain. Myoglobin is not cardiac-specific and therefore requires supplementation with some other analysis such as troponins to support the myoglobin value. Troponins are very highly cardiac-specific. Only the sera of some patients with severe renal failure, which requires hemodialysis, have elevated cTnT and/or cTnI without there being any evidence of cardiac damage. The latest studies have shown that elevated troponin levels in sera of hemodialysis patients point to an increased risk of future cardiac events in a similar manner to the elevated troponin values in sera of patiets with unstable angina pectoris. In addition, the bedside tests for cTnT and cTnI alone or together with myoglobin and CK-MB mass can be used instead of quantitative analyses in the diagnosis of patients with chest pain. These rapid tests are easy to perform and they do not require expensive instrumentation. For the diagnosis patients with chest pain, routinely myoglobin and CK-MB mass measurements should be performed whenever they are requested (24 h/day) and cTnT and cTnI on admission to the hospital and then 4-6 and 12 hours later and maintained less than 10% imprecision.
