Chest pain patients are a large burden of emergency department demand. Their effective care requires timely risk assessment. High-sensitivity assays for heart muscle damage (troponin) increases the ability to detect patients at low risk for heart attack but treatment rules based on these tests have not been fully validated. This randomised trial of clinical decision making based on new troponin tests will provide a guidelines for their efficient and effective use in emergency department care.
