The disclosure relates to an interactive, web based cardiovascular healthcare management system which has an infomediary site with databases having information relating to cardiovascular disease risk factors such as age, blood pressure, LDL, HDL and subfractions thereof and cardiovascular disease management such as diet, exercise, drugs and cardiovascular education materials. The physician can communicate electronically with the infomediary site to obtain patient test results and formulate a patient treatment plan from the diet, exercise and drug data. The physician can electronically communicate treatment plans to the patient through a record in the infomediary site. The patient can electronically communicate compliance information to the physician through the patient record. The infomediary site may also provide a case manager to provide initial draft treatment plans to the physician, gather patient history data and/or patient treatment plan compliance data.
