PY - 2020 T2 - Tintinalli's Emergency Medicine: A Comprehensive Study Guide, 9e AB - Of ED patients with undifferentiated chest pain, 7% will have ECG findings consistent with acute ischemia or infarction, and 6% to 10% of those in whom cardiac markers are ordered will have initially positive results.1 The remaining patients who do not have diagnostic ECG changes or initially positive cardiac marker results have low-probability or possible acute coronary syndrome (ACS; either infarction or ischemia including unstable angina pectoris). The evaluation of those with possible ACS costs approximately $10 billion to $12 billion each year in the United States.2 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/19 UR - accessmedicine.mhmedical.com/content.aspx?aid=1166531610 ER -
