Mobile Health Strategies for Veterans With Coronary Heart Disease

The purpose of this study is to determine whether text messages/messaging (TM) or a mobile
application (app), compared with an educational website-control provided to all Veterans, can
improve adherence to antiplatelet therapy among patients following acute coronary syndrome or
percutaneous coronary intervention (ACS/PCI).

Adherence to antiplatelet medications is critical to prevent life threatening complications
(i.e., stent thrombosis); yet rates of non-adherence range from 21-57% by 12 months. Mobile
technology through TM or mobile apps is a practical and inexpensive strategy to promote
behavior change and enhance medication adherence. The three specific aims of this proposal
are to: 1) determine preferences for content and frequency of TM to promote medication
adherence through focus groups; 2) determine the most patient-centered app to promote
adherence through a content analysis of all commercially available apps for medication
adherence and focus groups centered on usability; and 3) compare adherence to antiplatelet
medications in 225 Veterans post ACS/PCI through a randomized controlled trial. Participants
will be randomized to either TM, mobile app, or website-control group. The focus groups will
be stratified by low/high mobile phone use and sex.

Inclusion Criteria:

- ≥ 21 years of age,

- recent ACS or PCI within 1 week

- new antiplatelet (thienopyridine) prescription

- owns a smartphone

Exclusion Criteria:

- cognitive impairment

- lack of English proficiency/literacy
