This paper uses the hedonic price method (HPM) to evaluate the benefits from ameliorating serious cardiovascular disease. Data from the CVDFACTS project and NHI are used for the empirical analysis. Results using the quadratics model show that if we can ameliorate risk factors, such as hypertension, cholesterol and diabetes, among serious cardiovascular disease sufferers so that the risk levels are no higher than found in the general population the cost of medical service can be reduced NT$1,070, 423 and 418 million respectively. Using the log-linear model, results are NT$1,570, 508 and 1,130 respectively. Compared to cholesterol and diabetes, hypertension is relatively easy to ameliorate and the benefit is higher. In order to effectively prevent serious cardiovascular disease, the government needs to shift medical resources towards improving hypertension.
