The diagnosis and management of acute myocardial infarction and unstable angina pectoris are frequent challenges for emergency department staff. Strategies must quickly and accurately identify all patients requiring admission, monitoring, and reperfusion therapy to maximize outcomes without overdiagnosing. The Acute Cardiac Ischemia Time-Insensitive Predictive Instrument and the Thrombolytic Predictive Instrument are two decision-support tools designed to address this need. The instruments have been shown to improve some measures of the appropriateness of and time to emergency department triage. Prospective trials will be completed soon that will examine their effects on morbidity and mortality.
