Objective This study aims to analyze the characteristics of inpatients in the cardiovascular department of a tertiary hospital following the chest-pain-center accreditation,and provide guidance for the prevention and treatment of cardiovas-cular diseases.Methods A retrospective descriptive epidemiological approach was adopted to analyze the data of 2115 inpatients at the department of cardiovascular medicine in a tertiary hospital from 2022 to 2024 following chest pain center accreditation.Re-sults The number of the inpatients in 2022,2023,and 2024 was 582 cases(27.52％),684 cases(32.34％),and 849 cases(40.14％),respectively,with the total rising year by year.The proportion of males was higher than that of females,with a male-to-female sex ratio of 1.45∶1.The group aged 40 to 79 years accounted for the highest percentage(80.90％).The top three diseases categorized by percentage were coronary heart disease(754 cases,35.64％),hypertension(479 cases,22.64％),and arrhythmia(167 cases,7.89％).Epidemiological characterization exhibited a statistically significant difference in the disease composition of hospitalized cardiovascular patients in years,genders,ages,and seasons(x2=155.40,36.591,900.597,856.659,P＜0.05).Specific classification showed significant differences in hypertension and other conditions by age(P＜0.05);coronary heart disease and valvular heart disease by gender(P＜0.05);and significant differences across ages in coronary heart disease,hypertension,heart failure,pericardial disease,peripheral vascular disease,congenital heart disease,and others(all P＜0.05).Seasonal differences in coronary heart disease,hypertension,arrhythmia,cardiomyopathy,valvular heart disease,heart failure,pericardial disease,and others were also statistically significant(P＜0.05).Conclusion Against the backdrop of chest pain center accreditation in our hospital,inpatients in our department now demonstrate extinct demographic profiles and seasonal patterns among hospitalized cardiovascular patients.We should strengthen the prevention and treatment of coronary heart disease and hypertension,and establish a comprehensive prevention and control system based on these epidemio-logical characteristics.
