I. The development history of chest pain centers
The concept of chest pain centers was put forward to shorten the reperfusion treatment time of STEMI. Under the conditions at that time, many patients were often delayed in diagnosis and treatment due to atypical clinical manifestations, insufficient clinical experience of the receiving physicians, and irrationality of in-hospital diagnostic and treatment processes, and at the same time, there were also many patients with non-fatal chest pain who were admitted to the coronary care unit At the same time, many patients with non-fatal chest pain are admitted to the coronary care unit, resulting in a large waste of medical resources. The establishment of the Chest Pain Center is intended to shorten the reperfusion time of STEMI patients through the development of standardized diagnostic and treatment procedures, and at the same time to exclude non-fatal chest pain patients as soon as possible, in order to avoid the waste of medical resources.
Early concepts of chest pain centers mainly focused on the establishment of in-hospital fast-track diagnosis and treatment, but this kind of chest pain centers based on in-hospital green channel did not significantly shorten the reperfusion time of patients with STEMI, and around 2000, the U.S. statistic of the door-to-balloon dilatation (Door-to-Balloon, D-to-B) time of less than 90 minutes of the standard attainment rate was very low [1], and the U.S. statistics of the time between door and balloon dilatation were very low [1]. After that, the United States began to develop a system of percutaneous coronary interventions on a state or interstate regional basis, relying on a system with
