Abstract: Objective To analyze the diagnosis and treatment of acute coronary syndrome (ACS) inpatients in Xicheng district, Beijing, and put forward suggestions for coronary heart disease secondary prevention/cardiac rehabilitation. Methods Cluster sampling was carried out. ACS inpatients were screened by searching the home page of medical records of Xicheng district, Beijing between 2012.1.1—2016.12.31 based on the International Classification of Diseases (ICD)-10 codes from Beijing Municipal Health Information Center. Results The average onset age of ACS inpatients was 69 years old, and male patients accounted for 59.83% to 62.68%. Onset age ＞60 years accounted for about 70%; The percentage of 60＜onset age≤75 years old increased gradually. Non-st-segment elevation acute coronary syndrome (NSTE-ACS) including unstable angina(UA) and acute non-ST segment elevation myocardial(NSTEMI),accounted for 83.21% to 86.89% of the total ACS hospitalized patients.The percentage of hospitalized patients with unstable angina(UA) was more than 72.00% over the years. Coronary angiography was performed in 51.36% to 56.42% ACS inpatients. Percutaneous coronary intervention(PCI) treatment accounted for 9 342 person-time, accounting for 27.83 to 32.01% of the total ACS hospitalization. 26.32% to 30.28% of the ACS inpatients were performed Coronary stent implantation. PCI was performed in 48.21% to 54.89% of STEMI inpatients,30.90% to 33.56% of NSTEMI inpatients, and 22.33% to 27.14% of UA inpatients. Conclusions The main incidence of ACS in Xicheng district is NSTE-ACS. However, the proportion of patients receiving interventional therapy and revastigectomy is low. It is urgent to strengthen the prevention of cardiovascular disease and cardiac rehabilitation treatment, especially in the age population of 60-75.
