Introduction Chest pain is a frequent cause of admission to the emergency department (ED). The diagnosis and medical care of acute coronary syndrome (ACS) with ST-segment elevation (ST+ ACS) are more standardized than non ST-segment elevation ACS (NST ACS). There is very few series on patients classified as low ACS-diagnosis probability. We aimed to assess the 1-year outcome of patients admitted for chest pain in ED and discharged with low risk of ACS. Methods This restrospective study included all patients admitted in the ED of University Hospital Center of Limoges between January and March 2013 for chest pain, without ST-segment elevation and normal troponin level. Patients’ characteristics and initial diagnosis were collected in ED records. Final diagnosis was obtained by phone one year later, from general practitioners or alternatively directly from the patients themselves. Results Among the 244 patients studied, 38 (15.6%) were lost during follow-up. Mean age was 50±17 years, 58% being males. Among the 41% of cases in whom the initial diagnosis (i.e. ED discharge) was modified during follow-up, 9% (n=8) were diagnosed with coronary disease, and 38% (n=32) with panic attack. Major adverse cardiac events rate was 2.4% (n=5) in the whole population, and 60% of them were directly discharged to home. In the ED, the detection of a cardiovascular etiology of chest pain was accurate with good specificity (96%) but lower sensibility (61%). Of note, the rate of false negative patients was 8.5%. Conclusion Low probability NST SCA diagnosis is complex in the ED and may frequently lead to erroneous diagnosis associated with therapeutic delay. Nevertheless, cardiac disorders are uncommonly misdiagnosed. A systematic, individualized and close monitoring after ED discharge is mandatory. more...
