The study is a three-arm design where up to 600 patients hospitalized post-MI are recruited from a large hospital and randomized to either the education group (control group) or one of the two intervention groups. Patients randomized to one of the intervention groups will receive a nurse-administered intervention plus the use of Microsoft's HealthVault web-based platform or solely the use of Microsoft's HealthVault web-based platform and web-based behavioral intervention, both of which includes a behavioral/medication management component. The 12 months effects of the intervention will be evaluated.
