Self risk assessment for people to early find the risk and effective monitoring the variation of cardiovascular disease are important to the cardiovascular disease patients. However, to achieve this goal, it needs many services from distributive healthcare professionals and facilities. The decentralized nature of services makes it difficult to develop a single information system to serve all cardiovascular disease patients. In this research, we developed a self-assessment and monitoring system that based on the service-oriented architecture to coordinate the distributed services for cardiovascular disease patients. The service-oriented architecture for our proposed system consists of four layers: the web service interface, the service coordinator layer, the quality of service layer, and the health services layer. Based on this basic framework, we can develop a self risk assessment and monitoring system for cardiovascular disease patients. The scenario contained in the proposed system includes two phases: the cardiovascular disease risk assessment phase and the cardiovascular disease monitoring phase. In the first phase, the Framingham heart study estimation approach is adapted. An Estimation computing unit and an Interpreting unit are designed to accomplish the Framingham estimation. The Estimation computing unit reads parameters from two service sources, i.e., reads age, diabetes, smoker parameters from patient, and reads total cholesterol, HDL cholesterol, and blood pressure from hospital patient records or a laboratory test results. A point value that calculated from Estimation computing unit then input to the Interpreting unit to obtain the average 10 year risk. In the second phase, the current estimation result is compared with the patient’s past histories which stored in a database. Thus, the patient can monitor the variation of one’s condition. Furthermore, the monitoring results can offer the physician adequate information during the outpatient service. The main contribution offered by service-oriented architecture is that integrated the distributed service without put them together in real. It could help the healthcare industry to develop cost effective and dependable healthcare services.
