[Chest pain evaluation project].

The evaluation of acute chest pain remains challenging, despite many insights and innovations over the past two decades. The percentage of patients presenting at the emergency department with acute chest pain who are subsequently admitted to the hospital appears to be increasing. Patients with acute coronary syndromes who are inadvertently discharged from the emergency department have an adverse short-term prognosis. However, the admission of a patient with chest pain who is at low risk for acute coronary syndrome can lead to unnecessary tests and procedures, with their burden of costs and complications. Therefore, with increasing economic pressures on health care, physicians and administrators are interested in improving the efficiency of care for patients with acute chest pain. Since the emergency department organization (i.e. the availability of an intensive observational area) and integration of care and treatment between emergency physicians and cardiologists greatly differ over the national territory, the purpose of the present position paper is two-fold: first, to review the evidence-based efficacy and utility of various diagnostic tools, and, second, to delineate the basic critical pathways (describing key steps for care and treatment) that need to be implemented in order to standardize and expedite the evaluation of chest pain patients, making their diagnosis and treatment as uniform as possible across the country.
