0077 : Long-term clinical outcomes of patients having a chest pain negative evaluation in a dedicated Chest Pain Unit (CPU): Angers Hospital 3 year-experience

Background Chest pain is still one of the most frequent symptom in emergency department today. Chest pain units (CPU) have been developed to provide standardized care and rapid diagnosis, but few data exist in France about such structures. Aims To assess the prognosis of patients having chest pain without final diagnosis at the term of CPU evaluation. Methods Between January 2010 and December 2012, 1374 patients were admitted for non-traumatic chest pain in Angers Hospital CPU and analysed retrospectively. Clinical characteristics, final diagnosis and functional tests performed were noted. Primary outcome was major cardiac events (cardiovascular death or STEMI) occurring during the first year of follow-up. MACCEs, chest pain recurrence and rehospitalizations during long-term follow-up were analysed as secondary endpoints. Results 250 patients (18.2%) displayed an acute coronary syndrome and 678 (49.3%) had chest pain without final established diagnosis. Among them, only 1 patient displays a major cardiac event (cardiovascular death) Conclusion CPU evaluation is safe to rule out correctly acute coronary syndrome and patients presenting a negative evaluation display a low rate of major cardiac events. Further prospective studies are needed to support these preliminary results. The author hereby declares no conflict of interest
