Objective To assess the relationship between fine particulate matter (PM 2.5 ) concentration and ischaemic heart disease (IHD) morbidity and mortality. Methods A time-series study conducted in Beijing from 1 January 2010 to 31 December 2012. Data on 369 469 IHD cases and 53 247 IHD deaths were collected by the Beijing Monitoring System for Cardiovascular Diseases, which covers all hospital admissions and deaths from IHD from Beijing9s population of 19.61 million. Results The mean daily PM 2.5 concentration was 96.2 μg/m 3 with a range from 3.9 to 493.9 μg/m 3 . Only 15.3% of the daily PM 2.5 concentrations achieved WHO Air Quality Guidelines target (25 μg/m 3 ) in the study period. The dose–response relationships between PM 2.5 and IHD morbidity and mortality were non-linear, with a steeper dose–response function at lower concentrations and a shallower response at higher concentrations. A 10 μg/m 3 increase in PM 2.5 was associated with a 0.27% (95% CI 0.21 to 0.33%, p −16 ) increase in IHD morbidity and a 0.25% (95% CI 0.10 to 0.40%, p=1.15×10 −3 ) increase in mortality on the same day. During the 3 years, there were 7703 cases and 1475 deaths advanced by PM 2.5 pollution over expected rates if daily levels had not exceeded the WHO target. Conclusions PM 2.5 concentration was significantly associated with IHD morbidity and mortality in Beijing. Our findings provide a rationale for the urgent need for stringent control of air pollution to reduce PM 2.5 concentration.

Relationship between fine particulate air pollution and ischaemic heart disease morbidity and mortality

Noise produced by construction activities has become the second most serious acoustic polluting element in China To provide industry practitioners with a better understanding of the health risks of construction noise and to aid in creating environmentally friendly construction plans during early construction stages, we developed a quantitative model to assess the health impairment risks (HIA) associated with construction noise for individuals living adjacent to construction sites This model classifies noise-induced health impairments into four categories: cardiovascular disease, cognitive impairment, sleep disturbance, and annoyance, and uses disability-adjusted life years (DALYs) as an indicator of damage Furthermore, the value of a statistical life (VSL) is used to transform DALYs into a monetary value based on the affected demographic characteristics, thereby offering policy makers a reliable theoretical foundation for establishing reasonable standards to compensate residents suffering from construction noise A practical earthwork project in Beijing is used as a case study to demonstrate the applicability of the proposed model The results indicate that construction noise could bring significant health risks to the neighboring resident community, with an estimated 3451 DALYs of health damage and 2047 million yuan in social costs In particular, people aged 45–54 are most vulnerable to construction noise, with the greatest health risks being caused by sleep disturbance

DALY-Based Health Risk Assessment of Construction Noise in Beijing, China.

Background—The cost-effectiveness of the optimal use of hospital-based acute myocardial infarction (AMI) treatments and their potential impact on coronary heart disease (CHD) mortality in China is not well known. Methods and Results—The effectiveness and costs of optimal use of hospital-based AMI treatments were estimated by the CHD Policy Model-China, a Markov-style computer simulation model. Changes in simulated AMI, CHD mortality, quality-adjusted life years, and total healthcare costs were the outcomes. The incremental cost-effectiveness ratio was used to assess projected cost-effectiveness. Optimal use of 4 oral drugs (aspirin, β-blockers, statins, and angiotensin-converting enzyme inhibitors) in all eligible patients with AMI or unfractionated heparin in non–ST-segment–elevation myocardial infarction was a highly cost-effective strategy (incremental cost-effectiveness ratios approximately US $3100 or less). Optimal use of reperfusion therapies in eligible patients with ST-segment–elevation myocardia...

OBJECTIVE To survey the incidence of acute coronary events and its trend in three years, and explore the distribution of the incidence across Beijing residents aged 25 years and more from 2007 to 2009. METHODS The present study incorporated and linked the routinely collected data from the Hospital Discharge Information System and Cause of Death Register System in Beijing, estimated the incidence of acute coronary events, and analyzed the distribution of the incidence across gender, age groups and regions. Acute coronary event was defined as non-fatal myocardial infarction and death from coronary heart disease. Numbers of residents by age, gender and area were obtained from the Beijing Statistics Bureau. RESULTS A total of 68 390 acute coronary events were identified among permanent residents of Beijing aged 25 years and more from 2007 to 2009. The age-standardized incidence was 166.4 per 100 000 people in overall population, with 218.5 in males and 115.2 in females. The age-standardized incidence was 144.3, 154.7, and 195.8 per 100 000 people in urban, suburban, and exurban area, respectively. The incidence was the highest in Huairou district (263.8 per 100 000), while was the lowest in Haidian district (121.5 per 100 000). The age-standardized incidence was 158.4, 169.4, and 171.2 per 100 000 in 2007, 2008, and 2009, respectively. The age-standardized incidence increased by 8.1% in 2009 compared to 2007, increase in men (11.1%) was greater than in women (2.5%). The incidence increased significantly with age in each year. The incidence raised by 30.3% in 2009 compared to 2007 for men aged 35 - 44 years. In 2009, the incidence was 146.7, 155.9, and 207.4 per 100 000 people in urban, suburban, and exurban area, respectively. The rates increased by 3.2% in both urban and suburban areas, and 16.4% in exurban areas in 2009 compared to 2007. CONCLUSION The incidence of acute coronary events increased from 2007 to 2009 among the permanent residents of Beijing aged 25 years and over, especially in young men, and people living in the exurban areas.
