    Abstract:
    OBJECTIVE: To observe the changes of hospitalization rates and in-hospital mortality for coronary heart disease (CHD) in Beijing from 2007-2012. METHODS: Patients hospitalized for CHD in Beijing from 1 January 2007 to 31 December 2012 were identified from"The Cardiovascular Disease Surveillance System in Beijing". In total, 421 929 patients aged ≥25 years of permanent Beijing residents were admitted for CHD in Beijing during the 6 years. After excluding duplicate records and validation for the completeness and accuracy of the records, the hospitalization rates for CHD and in-hospital CHD mortality were analyzed. Trends in hospitalization rates and the in-hospital mortality for CHD were analyzed with Poisson regression models. RESULTS: The age-standardized average hospitalization rate of CHD was 515.3 per 100 000 population in patients aged ≥25 years in Beijing. During the six years, an increasing trend was observed in the hospitalization rates for CHD after adjusting the age and gender (P<0.001). The age-standardized hospitalization rates of CHD increased by 43.0% in the past six years. The greatest increases of hospitalization rates were noted in both men and women between 45 to 54 years. The age-standardized in-hospital mortality decreased from 3.3% to 2.2% over the time (P<0.001), with a in-hospital mortality reduction for acute myocardial infarction from 11.3% to 8.5%. CONCLUSIONS: An increasing trend in hospitalization rate was observed during 2007-2012 for Beijing residents aged ≥25 years, indicating an urgent need in CHD prevention in Beijing. The in-hospital mortality reduction during this period might reflect the improvement in the in-hospital treatment modalities of CHD.
