A clinical scoring system in undifferentiated chest pain predicting undetectable troponin concentration.

Background: Chest pain is the most common reason for emergency admission to hospital, but the majority of these are due to non-cardiac pain. We sought to determine which combination of clinical features is more likely to predict an undetectable troponin level in patients presenting with chest pain.

Methods: We collected data over a two-month period on consecutive patients presenting acutely to hospital with chest pain and who had a troponin I measured.
