Summary

Aims of the study:

Patients in a Chest Pain Unit (CPU) are examined to clarify if the cause of pain is cardiac or not. To identify patients with ST-elevation and other electrocardiogram (ECG) modifications a normal 12-lead ECG is used. The diagnosis non-st-elevation myocardial infarction is determined with the help of the ischemic marker Troponin. However, Troponin levels are elevated earliest 3 to 4 hours after the ischemic event, so that a negative Troponin result at the time of hospital admission is insufficient. Thus the guidelines of the German Society of Cardiology demand a second measurement after 6 to 12 hours. In rare cases false positive Troponin levels have been reported (e.g. in patients with renal insufficiency).

The aim of this study is to determine if in the early phase of diagnostic assessment cardiogoniometry can improve differentiation between patients with cardiac (ischemic) emergency and patients with non-cardiac (non-ischemic) cause of pain. Furthermore it will be evaluated if cardiogoniometry is capable to diagnose patients with non-ST-elevation myocardial infarction (NSTEMI) to the same extent as Troponin. This could avoid time loss until a possibly necessary catheter intervention ("fast track").

To clarify these questions the result of the cardiogoniometry will be compared with the leading diagnosis of the Chest Pain Unit, the diagnosis at hospital discharge as well as with the angiographic findings (as a gold standard). Therefore the performance of cardiac catheterization within 72 hours after start of symptoms is a mandatory inclusion criterion.
