Abstract
Patients complaining of chest pain (CP) who visit the emergency department (ED) represent the second cause of consultation in this department, and 20-30% of hospital admissions for medical reasons. These patients form a somewhat heterogeneous group with many different aetiologies and degrees of severity. In this setting, the clinical objectives include the prompt identification of patients with acute coronary syndromes (ACSs), the prompt evaluation of the immediate risk (i.e., initial risk stratification) of cardiovascular complications in order to tailor the treatment for each individual patient and to make the best use of hospital resources, and the prompt identification of patients with other potentially severe diseases. The diagnosis of ACS in patients coming to the ED for CP or any equivalent angina is one of the most difficult diagnostic challenges facing physicians in the ED. The correct diagnosis and risk stratification of these patients has clinical consequences, as well as very important legal and economic implications. The only methodology with a clear clinical impact on diagnosis, risk stratification and initial management is clinical evaluation based on data obtained by questioning the patient, carrying out a physical examination, and interpreting the results of a standard 12-lead electrocardiogram (ECG). Nevertheless, its combined diagnostic efficiency for ACS is imperfect and additional strategies are emerging which include serial ECG, the detection of serum biochemical markers of myocardial necrosis, exercise testing, and radionuclide myocardial perfusion imaging.
