Regular physical activity is important in the maintenance of cardiovascular health, and is especially critical for previously sedentary individuals who have undergone percutaneous coronary intervention (PCI) procedures. Changing behavior to adopt and maintain recommended physical activity levels in this population is difficult. Interventions to accomplish behavior change will not work unless they can be adopted into a person’s busy lifestyle. This proposed study fills a gap by testing the feasibility of an innovative, targeted intervention (Physical Activity Promotion Telehealth Intervention), delivered by a practical and feasible platform (cell phone). A two-group (n=50) repeated measures design will be employed with measures at baseline, 6-weeks, 3-months, and 6-months. The target population for this study is post-PCI patients living in rural areas.

Aim 1: Evaluate the feasibility of each component of this pilot study, in order to refine the intervention for a larger clinical trial. 

This will include:

  1. Evaluate all aspects of implementation (numbers of subjects contacted, enrollment, attrition; problems and solutions identified using the telehealth platform, time for delivery; subject acceptance and perception).
  2. Evaluate feasibility of the data collection methods (time required for data collection, missing data, reliability estimates of outcomes).
  3. Estimate effect sizes for sample size determinations for a future, larger clinical trial. 

Aim 2: Pilot test the impact of the Physical Activity Promotion Telehealth Intervention in post-PCI patients over time (6 weeks, 3 months, and 6 months) compared to patients receiving attention only, on the following outcomes:

  1. Movement through the stages of readiness for physical activity.
  2. Behavior change constructs (self efficacy for exercise, decisional balance, and use of processes for change).
  3. Amount of physical activity (estimated energy expenditure per day) and exercise (reported minutes exercising per day).
