title: Ten-year cardiovascular risk in a Hong Kong population.
abstract: BACKGROUND
  Cardiovascular disease is a major health issue in Hong Kong. We conducted a screening program to assess the 10-year risk for the population and to assess the potential benefit of large-scale screening in Hong Kong.
  
  
  METHODS
  A local screening program for cardiovascular risk was carried out in a health service network with a total of 17,716 participants. Retrospective data analysis for the prevalence and distribution of the various risk factors was performed. The data were then applied to calculate the 10-year risk of each individual, according to the European Task Force coronary risk chart.
  
  
  RESULTS
  Of the participants, 54.2% had total cholesterol levels > 5.2 mmol/l; 28.7% had body mass index > 25 kg/m2; 18.5% were hypertensive; 15.1% were smokers; and 3.7% had diabetes mellitus. There were 35.5% of the screened population who had at least two risk factors and 10.9% had at least three risk factors. A total of 9049 individuals satisfied the criteria for the European Task Force guidelines and were selected for 10-year cardiovascular risk analysis. We calculated that 68.0% of the male population had at least 10% risk and 41.5% had at least 20% risk of developing a coronary heart event within 10 years. Among women, 48.2% of the population carried at least 10% risk and 2.8% carried at least 20% risk.
  
  
  CONCLUSIONS
  The calculated 10-year risk of the population, particularly for men, is significant. Our study demonstrated that mass screening is feasible, and has the benefit of early identification of high-risk individuals, which could be a reasonable strategy for cost-effective medicine.
