  Purpose

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.

For baseline and outcome assessments we will obtain BP, nonfasting LDL, and Hb A1c. Patients will also be surveyed about demographics and health behaviors during the baseline and 12 months. Study personnel serve as a liaison between subjects and their providers; however, all decisions related to clinical care are ultimately left up to the patient's provider. Subjects with serious adverse effects will be advised and assisted in seeking emergency medical care.

Further study details as provided by Duke University:

Primary Outcome Measures:
  • The reduction of systolic blood pressure in the nurse administered intervention will be 5 mm hg lower than those patients randomized to an education control group over 12 months of follow-up [ Time Frame: 12 months ]

Secondary Outcome Measures:
  • Post-MI patients who receive the nurse administered intervention will have their LDL-C reduced by 20 mg/dl more than education control patients over 12 months of follow-up. [ Time Frame: 12 months ]
  • Post-MI patients with diabetes who receive the nurse-administered intervention will have their Hb A1c reduced by 0.5% more compared to education control patients over 12 months of follow up. [ Time Frame: 12 months ]
  • The reduction of systolic blood pressure in the web-administered intervention will be significantly more than those patients randomized to an education control group over 12 months of follow up. [ Time Frame: 12 months ]
  • Post-MI patients who receive the nurse-administered intervention will have higher use of evidence-based medical therapies (e.g., anti-platelets, statins, and ACE-I) compared with control patients at 12 months follow- up [ Time Frame: 12 months ]
  • Post-MI patients who receive either intervention will have improved health behaviors (e.g., physical activity, improved diet, lower body mass index) as compared with control patients over 12 months of follow-up [ Time Frame: 12 months ]

Arms Assigned Interventions
No Intervention: Control
Usual Care
Experimental: Web Intervention
Web-based: interactive web-based tool based on Microsoft's HealthVault technology for data transmission, tracking and communication of cardiac risk factors (e.g. home BP monitors for all in this intervention arm)
Behavioral: web intervention
A multi-behavioral, comprehensive approach is proposed addressing up to 13 health behaviors focused on improving subject management of CVD and related health behaviors. This is a web-based intervention.
Experimental: Nurse Intervention
Nurse: an interactive web-based tool based on Microsoft's HealthVault technology for data transmission, tracking and communication of cardiac risk factors (e.g. home BP monitors for all in this intervention arm)
Behavioral: nurse intervention
A multi-behavioral, comprehensive approach is proposed addressing up to 13 health behaviors focused on improving subject management of CVD and related health behaviors given by the nurse via phone.
