Brief Summary:
The purpose of this study is to assess the impact of text message reminders on adherence to medications and exercise in patients recently discharged from the hospital after a myocardial infarction (MI).

Condition or disease Intervention/treatment Phase
Myocardial Infarction Behavioral: Text message reminder for medication adherence Behavioral: Text message reminder for exercise regimen Not Applicable

Detailed Description:

The Impact of Text Messaging on Medication Adherence and Exercise Regimen among Post-Myocardial Infarction Patients includes two single-center randomized control trials to assess the impact of text message reminds on adherence to medications and exercise regimen in patients recently discharged from the hospital after MI.

Recruitment conducted at Cambridge Cardiac Rehabilitation in Ontario, Canada for both the medication adherence and exercise trial. Potential study subjects are evaluated for inclusion and exclusion criteria, give written informed consent, and are randomized, in a 1:1 ratio, to either intervention or usual care (control).

Patients randomized to the intervention arm in the medication adherence trial receive an automated text message once per day at the time they are prescribed to take their medication. The text message does not contain any personal or pharmacological information.

Patients randomized to the intervention arm in the exercise adherence trial receive four text messages per day at 7:30 am, 12:00 pm, 6:00 pm, and 9:00 pm, reminding them to exercise for 30 minutes per day as per their health care provider.

Arm Intervention/treatment
Experimental: Medication text message
Once daily text message reminder.
Behavioral: Text message reminder for medication adherence
Patients randomized to this arm receive one text message per day (at the scheduled time) reminding them to take their medication.

Experimental: Exercise text message
4x daily text message reminder.
Behavioral: Text message reminder for exercise regimen
Patients randomized to this arm receive 4 daily text messages reminding them to exercise for 30 minutes per day.

No Intervention: Usual care, medication adherence
Usual care for medication adherence.
No Intervention: Usual care, exercise regimen
Usual care for exercise regimen.



Primary Outcome Measures :
  1. Medication adherence [ Time Frame: 12 months ]
    Average medication adherence over 12 months after randomization, assessed with self-reported logs

  2. Exercise frequency [ Time Frame: 12 months ]
    Average frequency of exercise over 12 months after randomization, assessed with self-reported logs


Secondary Outcome Measures :
  1. Exercise duration [ Time Frame: 12 months ]
    Average duration of exercise assessed by BRUCE protocol

  2. Full medication adherence [ Time Frame: 12 months ]
    Average medication adherence over 12 months greater than .80
