From MedPage Today:
An accelerated diagnostic protocol in the emergency department identified a sizable group of symptomatic patients who were at low risk of having a short-term major cardiac event and who could be safely discharged, according to an observational study.
Assessment with a combination of Thrombolysis In Myocardial Infarction (TIMI) score, electrocardiogram, and baseline plus 2-hour troponin levels had a sensitivity of 99.7% (95% CI 98.1 to 99.9) and a specificity of 23.4% (95% CI 21.4 to 25.4) for identifying patients at low risk, according to Martin Than, MBBS, of the University of Otago in Christchurch, New Zealand, and colleagues.
