Controls (Standard CR) The standard cardiac rehab program is 8 weeks in duration, with patients exercising under supervision once per week in the JPCHH. Each session will consist of 30 minutes of cardiorespiratory exercise at a moderate intensity (60 to 80% of predicted heart rate max or maximum effort achieved during an exercise tolerance test) and a 5-minute warm-up and cool down period. Participants will be encouraged to supplement the JPCHH program with an additional optional 2-3 activity sessions per week to be performed in the home or a commercial exercise facility, in accordance with the standard therapy protocol of the JCPHH. No upper limit of training sessions will be set.
