    Abstract:
    OBJECTIVE: To examine the distribution and trends of hospitalization rates for coronary heart disease (CHD) from 2007 to 2009 in Beijing. METHODS: We calculated hospitalization rates for CHD using data from Beijing Hospital Discharge Information System. Information of census registered population in Beijing was obtained from Beijing Municipal Bureau of Statistics. CHD includes acute myocardial infarction, unstable angina and other forms of CHD. Age-standardized hospitalization rates for CHD per 100 000 population aged 25 years or more were calculated. RESULTS: During 2007 - 2009, a total of 248 049 patients aged 25 years or more hospitalized in Beijing with the primary discharge diagnosis of CHD were enrolled, of whom 73.7% were permanent registered Beijing citizens. The average hospitalization rate for CHD in 2007 - 2009 was 651.2/100 000 for the permanent residences in Beijing (741.2/100 000 in men, 560.9/100 000 in women). The highest average hospitalization rate (671.9/100 000) was seen in exurban area compared to other areas in Beijing. The average hospitalization rate for acute myocardial infarction, unstable angina, and other CHD was 126.4/100 000, 226.4/100 000 and 298.4/100 000, respectively. The hospitalization rate for CHD increased 18.1% from 2007 to 2009 (from 598.1/100 000 to 706.5/100 000). The same trend was seen in women (20.2%) and men (16.6%). The hospitalization rates of CHD in the urban, suburban, and exurban areas of Beijing all increased in the three years, and the greatest increase (36.6%) was found in exurban area. Hospitalization rates of acute myocardial infarction and unstable angina increased 24.5% and 55.3%, respectively, in the three years, while hospitalization rates of other CHD decreased 5.7%. CONCLUSIONS: The hospitalization rate of CHD is higher in men than in women in Beijing. The hospitalization rates for CHD increased from the observation period, especially in those living in exurban area. Awareness of the magnitudes and trends of CHD hospitalization rates is of great importance in evaluating the burden of cardiovascular disease, allocating and utilizing health care resources, and estimating the health insurance for Beijing.
