title: Coronary heart disease: incidence, risk factors and interventions in Jiaozhou of Shandong province.
abstract: BACKGROUND
  Coronary heart disease (CHD) is the most common type of heart disease and cause of heart attacks. This study investigated the epidemiological characteristics of CHD and its risk factors in Jiaozhou, Shandong province, to ultimately find a way of reducing the prevalence of cardiovascular disease, and to provide a theoretical basis for establishing a cardiovascular disease management path under the regional medical collaborative mechanism.
  
  
  METHODS
  A questionnaire survey was performed including 1 952 people aged 35 years or older who were questioned by means of stratified, cluster, proportional sampling to investigate the prevalence of CHD and its risk factors. The data were inputted into SPSS11.0 statistical software for processing and analysis. We advised the local medical institutions to establish health files for the residents with CHD and risk factors. They were followed up regularly. Their risk factors and life-style were monitored, and advice was given as to proper medications. Green channels were established, and the patients were transmitted in a timely manner to superior hospitals for better treatment if the necessary treatments were not available in the local hospitals. The control of risk factors was observed after the follow-up for half a year.
  
  
  RESULTS
  In Jiaozhou, the rates of coronary artery disease, hypertension, diabetes, hyperlipidemia and overweight were 8.15%, 28.54%, 11.43%, 35.46%, and 18.70% respectively. The rates of hypertension, diabetes, hyperlipidemia and overweight were higher than the data published in "The report of Chinese cardiovascular disease 2012"; which are 24%, 9.7%, 18.6%, and 9.7%, respectively. The control of risk factors improved significantly after the guidance of the residents lifestyle and medication for six months.
  
  
  CONCLUSIONS
  The high prevalence of coronary artery disease in Jiaozhou is closely related to age, gender, diet structure, family history of cardiovascular disease, hypertension, diabetes, hyperlipidemia, overweight, and unhealthy lifestyle. Under the regional medical coordination mechanism, the collaborative management of cardiovascular disease can provide new management concepts for the areas short of medical resources, so as to reduce the prevalence of cardiovascular disease.
