초록

The mortality rate of ischemic heart disease (IHD) was the highest rate of any heart diseases in South Korea. In this study, we predict the absolute risk factors of IHD according to individual characteristics or health status. Cox proportional hazards regression models were fitted to estimate hazard ratio of risk. Stepwise method was used to select a final model. After predictors were selected, the results were used to estimate the absolute 10-year IHD risk using Framingham risk score function and to calculated a simple point system. The total observation period for 106,167 subjects was 1,071,584 person-years. During the observation period, 4,627 subjects (4.4%) developed IHD with incidence rate of 431.79 per 100,000 person-year. Sex, age, smoking, drink, blood pressure, fasting blood sugar and total cholesterol were included in the final model. A Harrell?s c-index was 0.732l as a measure of discrimination and the overall O/E ratio was 0.972 (95% CI 0.944-1,000). We have predicted a model for 10-year risk of IHD related to risk factors using NHIS-NSC. Using these results, if you have your health information, you will be able to predict your risk of IHD.
