Brief Summary

Cardiac rehabilitation (CR) is strongly recommended for patients with coronary heart disease. However, patient enrollment and completion of cardiac rehabilitation is low. This study will examine if a mobile phone intervention that uses a text messaging program can successfully promote participation in cardiac rehabilitation.

Detailed Description

Mobile phone interventions, such as text messaging programs, have been shown to promote healthy behaviors in patients with coronary heart disease, but it is unknown whether text messaging can successfully promote participation in cardiac rehabilitation.

This study will have the following aims:

Aim 1: Adapt a theory- and evidence-based text messaging intervention to promote participation in cardiac rehabilitation.

Aim 2: Determine whether text messaging improves participation in cardiac rehabilitation among eligible patients.

This study will have two parts. In part 1, the investigators will enroll patients with heart disease to rate the acceptability of text messages. In part 2, the investigators will enroll patients to participate in a randomized controlled trial. Participants will be randomized to receive text messages or no text messages for 6 months. Those who have been assigned to receive the text messaging intervention will be sent several text messages per week throughout the study period. The content of these text messages is designed promote healthy behaviors and participation in cardiac rehabilitation. Those who have not been assigned to receive the text messaging intervention will receive usual care. Outcome measures will be assessed at a baseline visit and at a 6-month follow-up visit at the end of the intervention. Additionally, some participants in the text messaging intervention group will be interviewed about their overall satisfaction and engagement with the text messages upon completion of the study.

Primary Outcome Measures
NameTimeMethod
Attendance at cardiac rehab6 months

Documented attendance at one or more cardiac rehab sessions. Primary analysis will compare the proportion attending cardiac rehab in the text message intervention and no text message intervention arms.

Secondary Outcome Measures
NameTimeMethod
Number of cardiac rehab sessions attended6 months

Documented attendance at cardiac rehab sessions

Patient activation6 months

Self-reported activation via the Patient Activation Measure 13 (PAM-13)

Patient satisfaction6 months

Self-reported satisfaction with the intervention

Tobacco use6 months

Participant self-report of tobacco use in past 30 days

Cholesterol (LDL)6 months

Obtained from medical records

Physical activity6 months

Self-reported via International Physical Activity Questionnaire (IPAQ) - Total physical activity in continuous MET-min/week. Total physical activity is the sum of walking, moderate, and vigorous physical activity. Walking MET-minutes/week = 3.3 \* walking minutes \* walking days. Moderate MET-minutes/week = 4.0 \* moderate-intensity activity minutes \* moderate days. Vigorous MET-minutes/week = 8.0 \* vigorous-intensity activity minutes \* vigorous-intensity days.

Exercise capacity6 months

6-minute walk test (6MWT)

Body Mass Index (BMI)6 months

Weight measured by study staff. BMI = weight (kg) / height in meters squared (m2)

Death6 months

Confirm participant-reported events from medical records. We will report a composite of number of participants with Hospitalizations, ER visits, or Death, as well as number of participants with each individual outcome.

Depressive symptoms6 months

Self-reported depressive symptoms via Patient Health Questionnaire-9 (PHQ-9). Scored 0-27 with 0 representing no depressive symptoms and 27 representing severe depressive symptoms.

Diet6 months

Self-reported diet via Rate Your Plate questionnaire. Score 23-69, with 69 representing best diet.

Blood pressure6 months

Blood pressure measured by study staff

Disease-specific health status6 months

Self-reported health status via validated Kansas City Cardiomyopathy Questionnaire (KCCQ) - Short Form for participants with heart failure or valvular heart disease. The questionnaire is scored from 0-100 with 100 being the highest reportable health status. KCCQ domains will include: Physical Limitation, Symptom Frequency, Quality of Life, and Social Limitation.

Patient experience6 months

Self-reported experience with the intervention

ER visits6 months

Confirm participant-reported events from medical records. We will report a composite of number of participants with Hospitalizations, ER visits, or Death, as well as number of participants with each individual outcome.

Hospitalizations6 months

Confirm participant-reported events from medical records. We will report a composite of number of participants with Hospitalizations, ER visits, or Death, as well as number of participants with each individual outcome.
