Designing a Health Coach-Augmented mHealth System for the Secondary Prevention of Coronary Heart Disease Among Women.

While the number of women with Coronary Heart Disease requiring cardiac rehabilitation (CR) continues to increase, lack of access and other barriers to center-based CR present significant challenges. A mobile phone and wearable device-based technological system can offer home-based secondary prevention program for CHD. We have designed a women-specific digital health intervention system for use in a home-based CR program. The system that we have proposed combines human-expert intelligence with machine intelligence to enhance the decision-making capability of a health coach. We have evaluated the prototype of our system with eight women with CHD for over 13 weeks. The evaluation has shown a significant positive impact of preprogrammed intervention messages on participants’ walking performance on the same and the next day. Since increased walking activities directly improve heart health, we can directly infer that our proposed system is beneficial as a tool for secondary prevention among women with CHD.
