Abstract

Background: Chest pain is one of the most common complaints in the emergency department. Acute coronary syndrome with ST-segment elevation remains the ultimate medical emergency. However, acute coronary syndrome without ST-segment elevation (NSTE -ACS) has an equivalent prognosis risk. The major challenge of the emergency physician is the rapid and accurate identification of patients with ACS who would benefit from immediate care.
Objective:
Evaluation of our practices according to European Recommendations for the  management of NSTEACS and assessment of short and long-term prognosis for major cardiovascular events (MACE).
Methods: This is an analytical study, involving 850 patients treated for NSTE-ACS for 2 years in the emergency department. Data were collected from the acute coronary syndromes’ local register (ReSCUS register). The main results were: the different delays in medical care, length of stay in the emergency department, short-term complications, and the occurrence of MACE registered at one month, six months, and one year later.
Results: The average age of our patients was 64 +/- 11 years. The sex ratio was 2.2. Hypertension and diabetes are the two most common risk factors in our population. NSTE-ACS was inaugural in almost a third of the cases. Only 7% of the patients have been referred to the ED by a medical team.
In 16.2% of cases, the initial ECG found no repolarization disorder. The average first medical contact delay was 24.4 +/- 30.2 min. The average first qualifying ECG delay was 30 +/- 0.6 min. The average length of stay in the emergency department before admission to the cardiology department was 24.1 +/- 21.3 hours. More than half of the sample (68%) had their angiograms within 48 hours. Among the 500 followed-up patients, 12 were completely lost. Patients who presented at least one MACE were
at one month: 58 patients (11.6%) at 6 months: 112 patients (22.4%), and at 1 year 136 patients (27.2%).
Conclusion: Cardiovascular disease is the leading cause of death worldwide. Assessment of our practices is important to improve prognosis. Registers offer a guarantee of methodology and are a real mirror of our medical care.
