Abstract: Objective To analyze the disease spectrumand hospitalization expenses of inpatients withcardiovascular disease（CVD）, understand the rules and characteristics of disease composition, and provide reference for the diagnosis and treatment of CVD. Methods Retrospectively analyzed the relevant data of CVD inpatients in a tertiary hospital in Panzhihua, 2017-2019, and derived the data of the case entries, detailed medical records, and hospitalization expenses of cases diagnosed with CVD from the relevant management information system of the hospital. Descriptive epidemiological analysis method was used to analyze the data of inpatients with CVD. Results A total of 11 376 inpatients with CVD were included. From 2017 to 2019, there were 3 492, 3 815, and 4 069 cases were included, accounting for 30.7%, 33.5%, and 35.8%, respectively. The number of cases increased year by year. There was no statistically significant difference in the gender distribution of inpatients with CVDamongthe three years （P>0.05）, butthe difference in age distribution was statistically significant （P<0.01）.The onset age of inpatients with CVD tended to be younger. Coronary heart disease（CHD） and hypertension accounted for the largest proportion, accounting for 57.6% and 55.5% of inpatients with CVD in the same year, respectively, which increased to 62.8% in 2019.There was no significant difference in the proportion of inpatients with concomitant diseases （27.6%, 26.1%, 25.4%） amongthe threeyears （P>0.05）.There was statistical significancein the distribution of hospitalization days for patients with CVD （P<0.01）. In 2019, the proportion of patients staying<7 days increased. In 2017, 2018 and 2019, the out-of-pocket expenses for diagnosis and treatment of CVD inpatients were （5 925.6±285.7）, （5 904.2±264.3）, （5 890.9±230.8） yuan/person, and the difference was statistically significant （P<0.01）. Conclusion From 2017 to 2019, the number of inpatientswithCVD in a hospital in Panzhihua has increased, and the onset age of inpatients tend to be younger. The main diseases arestill CHD and hypertension, and the number of days of hospitalization and out-of-pocket expenses have showed a decreasing trend.
