Current Status and Determinants of Care for Patients With Acute Chest Pain in China: A Retrospective Analysis of Data From the China Chest Pain Center Registry (CHANGE)

Chinese Cardiovascular Association is an association dedicated to establishing Chest Pain Centers in hospitals that have basic qualifications and meet pre-designed quality control targets.The vision of Chinese Cardiovascular Association is the cardiovascular health of every Chinese, and the mission is to realize the early arrival of the inflection point of cardiovascular events in China.The institute of China Heart House is responsible for the daily management and implementation of Chinese Cardiovascular Association and the implementation and management of the Chest Pain Center construction project.In order to improve standard treatment and chest pain system management to achieve better outcomes for patients, China Heart House established the chest pain center database.The database includes patients in 6000 registered hospitals in 31 provinces in China who have been admitted with chest pain.The database can reflect the clinical characteristics, treatment and outcome of patients with chest pain in China.

This non-interventional, retrospective study analyzed the chest pain center database to understand the demographics, clinical characteristics, treatment patterns and clinical outcomes of patients with chest pain, and to analyze the effects of different treatment patterns, including chest pain centers and related collaborative treatment networks.The results of the study will assess the gap between the real-world situation and the recommendations of the guidelines and reflect the effect of chest pain centers and related collaborative treatment networks on the treatment process and service quality.The research results can be directly translated into the basis of medical treatment system intervention, and also provide decision-making reference for improving the evaluation standards and quality control of chest pain centers.

Study Population

The study population was inpatients (18 years and older) admitted to the Chest Pain Central database with symptoms of chest pain.The database registration of this study was conducted in more than 6000 registered hospitals in 31 provinces in China.All hospitals participating in the Chest Pain Center program are encouraged to manage patients in accordance with local standard practices (as recommended by current Chinese guidelines).

This study will include data on all patients in the chest pain central database.
