Chest pain in the emergency room. Importance of a systematic approach.

Objective: To evaluate the efficiency of a systematic diagnostic approach in patients with chest pain in the emergency room in relation to the diagnosis of acute coronary syndrome (ACS) and the rate of hospitalization in high-cost units.

Methods: One thousand and three consecutive patients with chest pain were screened according to a preestablished process of diagnostic investigation based on the pre-test probability of ACS determinate by chest pain type and ECG changes.

Results: Of the 1003 patients, 224 were immediately discharged home because of no suspicion of ACS (route 5) and 119 were immediately transferred to the coronary care united because of ST elevation or left bundle-branch block (LBBB) (route 1) (74% of these had a final diagnosis of acute myocardial infarction [AMI]).
