External Validation of the SCARE Score

The main objective is to validate the predictive SCARE score of acute coronary syndrome during the medical assessment of chest pain. The primary endpoint will be SCARE score analysis (pre-established in 2016) with assessment of its calibration (Hosmer Lemeshow) and discrimination (AUC) in a multicenter population of chest pain with a potential diagnosis of Acute Coronary Syndrome established according to the European Society of Cardiology criteria. This is a multi-center study including any patient over 18 years of age calling call center for chest pain over a period of six months. It will exclude post-traumatic chest pain, patients under 18 years old, patients who do not speak French, patients refusing to participate in the study or refusing treatment, patients not affiliated to social security, patients incarcerated in a penitentiary center, patients under tutorship, curatorship or safeguard of justice. The collection of data will be carried out thanks to files filled prospectively by the medical physician for each call for the reason of a chest pain. These cards will list the epidemiological data (age, sex, weight, height) and clinical data of each patient, as well as the decision and the resources committed by the regulating physician (hospital care via SMUR or ambulance, treatment in city medicine). For hospitalized patients, the diagnosis of ACS will be retained if the patient meets the criteria defined by the European Society of Cardiology. For patients managed in ambulatory medicine, a telephone call to the patient will be made at one month to obtain the diagnosis. Then, the SCARE score will be analized in this multicenter population with evaluation of its calibration (Hosmer Lemeshow) and discrimination (AUC). The characteristic performances of the score (sensitivity, specificity, PPV, NPV, positive and negative likelihood ratios)will also be analized.
