La prise en charge rapide des douleurs thoraciques aux urgences

Acute chest pain is a common reason of consultation in the emergency department. The difficulty lies in discriminating patients with acute coronary syndrome or other life-threatening conditions from those non-cardiovascular, non-life-threatening chest pain. Only 15 to 25 % of patients with acute chest pain actually have acute coronary syndrome. Algorithms using high sensitivity troponin at admission and a second assessment 1 or 3 hours later are validated to “rule in” or “rule out” the diagnosis of non ST-elevation myocardial infarction. This may reduce the delay for the diagnosis translating into shorter stay in the emergency department. Those algorithms must be interpreted in the context of clinical and ECG criteria.
