Using the ecological interface design approach, a graphical user interface was developed to show how different factors (e.g., LDL, HDL, triglycerides, systolic blood pressure) contribute to cardiac health. The display is based on an epidemiological model derived from the Framingham study and additional treatment guidelines in the medical literature. This interactive display allows physicians and patients to see how different factors contribute to overall cardiac health and to see the impact of interventions on reducing risk. The display also graphically associates the state of the patient with treatment categories to help physicians to select the best treatment method based on empirical models. It also has the potential to enrich the dialogue between physician and patient through interactive ‘experiments’ that illustrate the potential benefits of various treatment options.
