Home-Based Exercise Cardiac Telerehabilitation on Adherence and Functional Capacity for Patients After Percutaneous Coronary Intervention in Indonesia: Protocol for a Quasi-Experimental Study

Q: What is the clinical evidence from this study?

Population: Coronary artery disease after percutaneous coronary intervention (n=63). Intervention: Home-based exercise cardiac telerehabilitation (HBECTR) vs. Usual care (center-based cardiac rehabilitation 2 sessions per week). Primary outcome: Adherence to cardiac rehabilitation (percentage of completed sessions).

Key result

Pilot trial protocol evaluates home-based cardiac telerehabilitation adherence in post-PCI patients.

n=63

Why the study?

Cardiac rehabilitation remains underutilized, and monitoring patient adherence and safety during home-based exercise is challenging.

Does home-based exercise cardiac telerehabilitation improve adherence and functional capacity in adults after successful percutaneous coronary intervention?

Structured PICO

Does home-based exercise cardiac telerehabilitation improve adherence and functional capacity in adults after successful percutaneous coronary intervention?

Population

63 adult patients with coronary artery disease after successful percutaneous coronary intervention enrolled in a 4-week pilot feasibility study of home-based exercise cardiac telerehabilitation.

Intervention

Home-based exercise cardiac telerehabilitation (HBECTR): 5 moderate-intensity 45-minute aerobic exercise sessions per week (2 supervised in-hospital sessions and 3 home sessions) for 4 weeks. Home sessions are remotely monitored via CovWatch smartwatch and App Rehab Cardio dashboard tracking heart rate, blood pressure, oxygen saturation, and distance.

Comparator

Standard care (center-based cardiac rehabilitation): 2 supervised 45-minute moderate-intensity aerobic exercise sessions per week at the hospital for 4 weeks, with unmonitored independent home exercise suggested.

Outcome

Patient adherence to the exercise-based cardiac rehabilitation program (calculated as the percentage of attended sessions out of prescribed sessions, with ≥80% considered adherent) at 4 weeks.

Limitations

Quasi-experimental design without randomized assignment introduces potential selection bias.
Nonconcurrent enrollment introduces time-related biases.
Modest sample size limits statistical power and generalizability.
Short follow-up duration (4 weeks) limits assessment of long-term sustainability.
Lack of full participant and assessor blinding due to the overt nature of the intervention.
Feasibility challenges including variable access to technology, digital literacy differences, and potential missing data from remote monitoring.
Limited number of eligible participants
Nonconcurrent enrollment introduces potential time-related biases
Full blinding of participants and assessors was not possible

Implication

This study protocol describes a quasi-experimental pilot trial assessing the feasibility, adherence, and functional outcomes of a 4-week smartwatch-monitored home-based cardiac telerehabilitation program for post-PCI patients in Indonesia.

Wantiyah et al. (2025) studied Coronary artery disease after percutaneous coronary intervention (n=63). Home-based exercise cardiac telerehabilitation (HBECTR) vs. Usual care (center-based cardiac rehabilitation 2 sessions per week) was evaluated on Adherence to cardiac rehabilitation (percentage of completed sessions). This paper is a study protocol for a pilot quasi-experimental trial evaluating home-based exercise cardiac telerehabilitation in post-PCI patients, with primary clinical outcomes pending data analysis.
