Identifying which patients presenting with undifferentiated chest pain are at risk of major cardiac events is a major clinical challenge. Clinical evaluation may lack sufficient precision, leading to unnecessary admission or inappropriate discharge. It is uncertain whether risk scores derived from ACS populations apply to unselected patients with chest pain. ⋯ In unselected patients presenting with suspected cardiac pain, the GRACE risk score is superior to the TIMI risk score in predicting major cardiac events, and both risk scores are superior to using ECG and troponin findings at presentation.
