ABSTRACT

Background:

Remote cardiac rehabilitation (RCR) after myocardial infarction is an innovative Israeli national program in the field of tele-cardiology. RCR is included in the Israeli health coverage for all citizens. It is generally accepted that telemedicine programs better apply to younger patients, because it is thought that they are more technologically literate than older patients. It has also previously been thought that older patients have difficulty utilizing technology-based programs and attaining program goals.

Objective:

The objectives of this study were as follows: 1) To study patterns of physical activity, goal achievement, and improvement in functional capacity among RCR patients over 65 compared to younger patients and 2) To identify predictors of better adherence with the RCR program.

Methods:

A retrospective study of post-myocardial infarction patients were enrolled in a six-month RCR program. The activity of the patients was monitored using a smartwatch. The data was collected and analyzed by a special telemedicine platform. RCR program goals were: (i) 150 minutes of aerobic activity per week; (ii) 120 minutes of the activity in the target heart rate recommended by the exercise physiologist; (iii) 8,000 steps per day. Models were created to evaluate variables predicting adherence with the program.

Results:

Out of 306 patients, 80 were elderly (average age 70 ± 3.4). At the end of the program, there was a significant improvement in the functional capacity of all patients (P < .001). Specifically, the elderly group improved from 8.1 ± 2.8 to 11.2 ± 12.6 Metabolic equivalent of task (METs) and their final METs results were similar to younger patients. During the entire program period, the elderly group showed better achievement of program goals compared to younger patients (P < .01). Additionally, we found that younger patient age is an independent predictor of early dropout from the program and completion of program goals (P < .01); younger patients were more likely to experience early program dropout as well as complete fewer program goals.

Conclusions:

Elderly patients demonstrated better compliance with and achievement of the goals of the remote rehabilitation program in comparison with younger ones. We found that older age is not a limitation, but instead a predictor of better RCR program compliance as well as program goals achievement.
