Abstract 14588: Incidence of Acute Coronary Events in the Permanent Residents of Beijing During 2007-2009
Background This study was aimed to examine the recent incidence rates of acute coronary events in the permanent residents of Beijing from 2007 to 2009.
Methods The Beijing Acute Myocardial Infarction Surveillance Platform was established by linking the routinely collected data from the Hospital Discharge Information System and Cause of Death Register System in Beijing. Acute coronary event was defined as non-fatal myocardial infarction or death from coronary heart disease. All hospital admissions or death for the same patient occurring within 28 days were considered as one episode. Age-standardized incidence rates of acute coronary events per 100,000 people aged 25 years and more were calculated.
Results A total of 68,390 acute coronary events were identified among permanent residents of Beijing aged 25 years and more during 2007-2009. The age-standardized incidence was 158.4, 169.4, and 171.2 per 100,000 people for 2007, 2008, and 2009, respectively. The rate increased by 8.1% in the year 2009 compared to 2007, with a greater increase noticed in men (11.1%) than in women (2.5%). In 2009, the rate was 227.7 and 115.5 per 100,000 people for men and women, respectively. The incidence increased significantly with age in each year. During the 3 years, the rates raised in all age groups, except for the age group of 25-34 year and 85 year or more. In particular, the rate raised by 37.4% for the 35-39 year age group in the year 2009 compared to 2007, the largest increase in all age groups. In 2009, the incidence was 146.7, 155.9, and 207.4 per 100,000 people in urban, suburban, and exurban area, respectively. Compared to 2007, the rates in 2009 raised 3.2% in both urban and suburban areas, and 16.4% in exurban area.
Conclusions The incidence of acute coronary events increased notably among the permanent residents of Beijing aged 25 years and more during 2007-2009. More unfavorable changes have been shown for men, the younger age group, and the exurban area, which coincide with the unhealthier lifestyle and worse risk factor profile in these populations. Current data may guide future policy-making for public health and help to determine priorities for the prevention of heart disease in large cities, like Beijing, which leads rapid socioeconomic changes with profound effects on health.
