title: [A prospective study on 6-year accumulative incidence rate of ischemic cardiovascular disease and related risk factors among the elderly male population under health care programme].
abstract: OBJECTIVE
  To investigate the 6-year accumulative incidence rate of ischemic cardiovascular disease (ICVD) and its related risk factors.
  
  
  METHODS
  Baseline population was all from an elderly population with members all born before 1-1, 1938 and under health care programme. Data was recorded in a database of a hospital and baseline of subjects under research was aged >65 years. People that had had ICVD at baseline were excluded. Risk factors under research would include:age at the baseline study, gender, body mass index, systolic blood pressure, serum cholesterol level, serum triglyceride level, serum high-density lipoprotein level, serum triglyceride level, serum apolipoprotein A1 level, history of diabetes mellitus and cigarette smoking etc. Single factor analysis was carried out using person-years as time of study, then calculating the person-year incidence and the accumulative incidence rate at different levels related to baseline risk factors. Multivariate analysis was under Cox Proportional Hazards Regression Model.
  
  
  RESULTS
  Baseline population included 2271 elderly men, with the 6-year cumulative prevalence rate of ICVD as 23.56%, and the person-year prevalence rate was 45.41‰. Single factor analysis showed that the ICVD events positively related to variables which including systolic blood pressure, body mass index, serum cholesterol level and serum triglyceride level, serum apolipoprotein A1 level, status of diabetes mellitus and cigarette smoking. The ICVD events negatively related to variables as serum high-density lipoprotein level and serum creatinine level. Results of multivariate analysis showed that high systolic pressure, diabetes mellitus, serum creatinine level, Body Mass Index were the main risk factors. The serum high-density lipoprotein level served as the main protective factor.
  
  
  CONCLUSIONS
  The aged male population under health care programme was high in the ICVD prevalence rate, suggesting that programmes as controlling blood pressure, blood glucose, and increasing serum high-density lipoprotein levels were effective measures to decrease the ICVD events.
