Thoracic pain can be caused by a myocardial infarction. The diagnosis of a myocardial infarction can be made by an ECG (ST-elevation myocardial infarction, STEMI). However, some myocardial infarctions can also occur without ST-elevations on the ECG (non-ST-elevation myocardial infarction, non-STEMI). In the latter case, a quick acquisition of blood troponin levels is necessary to coin the diagnosis and initiate treatment. Therefore, the investigators prospectively want to compare 3 clinical tests for measuring blood troponin levels in patients presenting to the emergency room with thoracic pain probably related to a non-STEMI with regard to the time necessary to obtain the test results.~The 3 tests are:~A laboratory based test: Roche Cobas E 602~A point of care test: Radiometer AQT 90 Flex~A point of care test: Philips Minicare I-20~The measured timeframe is the time between venipuncture to the point the test results are known.
