Brief Summary
The study is a two-arm, parallel, randomized clinical trial. The purpose of the study is to evaluate the effectiveness of automated mobile phone text message-based intervention for secondary prevention, including lifestyles modification, medication adherence improvement and risk factors control among coronary heart disease (CHD) patients with diabetes. The participants will be randomized into intervention and control groups in a 1:1 ratio. The intervention group will receive 6 pre-designed text messages per week in addition to usual care for 6 months, while the control group will receive usual care.

Intervention-Text messaging
EXPERIMENTALPatients will receive regular semi-personalized text messages for 6 months. Each participants will receive 6 text messages per week, which will be sent at random times of the day (9.00am, 12noon, 4.00pm). They will receive one general messages, one hypertension message, one glucose control message, one lifestyle message, one medication adherence message and one physical activity message per week.
Control
NO INTERVENTIONParticipants in the control group will receive 2 thank-you messages per month and undertake routine clinical practice.
Interventions
Patients will receive regular semi-personalized text messages for 6 months. Each participants will receive 6 text messages per week, which will be sent at random times of the day (9.00am, 12noon, 4.00pm). They will receive one general messages, one hypertension message, one glucose control message, one lifestyle message, one medication adherence message and one physical activity message per week. Prior to study commencement, a bank of 270 messages have been developed based on guidelines and behavior change theory (BCT), and have underwent multidisciplinary expert review and qualitative review process.
