Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this observational study is to evaluate whether a home-based cardiac tele-rehabilitation program can improve functional capacity in adults (18 years and older) with chronic heart failure. The main questions it aims to answer are:

Does tele-rehabilitation improve peak oxygen uptake (VO₂ max) compared to standard in-hospital rehabilitation? Does it improve cardiac function, exercise tolerance, biochemical markers, and quality of life? Are functional gains maintained at 24 weeks? Researchers will compare patients who opt for tele-rehabilitation using wearable devices and a remote monitoring platform with those undergoing standard in-person rehabilitation. Participants will follow an 8-week individualized training program and undergo assessments at baseline, 4, 8, 16, and 24 weeks.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This prospective, single-center, non-pharmacological observational study aims to evaluate the effectiveness and feasibility of a structured, home-based cardiac telerehabilitation program in adults with chronic heart failure (CHF). The primary objective is to determine whether a telemedicine-based model can improve patients' functional capacity, as measured by maximal oxygen uptake (VO₂max), when compared to conventional in-hospital cardiac rehabilitation.

Participants will voluntarily enroll in either the telerehabilitation group or the standard rehabilitation group. Both groups follow the same 8-week aerobic exercise protocol, based on current international guidelines for heart failure management. The program includes warm-up, interval and endurance training, and cooldown, with exercise intensity personalized using cardiopulmonary exercise testing (CPET).

The telerehabilitation group will perform all sessions at home using a certified telehealth platform (Khymeia Virtual Reality Rehabilitation System - VRRS), which enables real-time supervision via secure videoconferencing. Participants are equipped with wearable medical-grade sensors for continuous monitoring of electrocardiogram (ECG), heart rate, blood pressure, and peripheral capillary oxygen saturation (SpO₂). The system offers automated data recording, performance feedback, and safety alerts, ensuring standardized care delivery and real-time clinical oversight. Before home-based training begins, participants receive structured in-person training to ensure safe and effective use of the digital tools.

Clinical and functional data are collected at baseline and follow-up visits at 4, 8, 16, and 24 weeks. The study also investigates patient adherence, safety, and the usability of digital rehabilitation tools. No investigational drugs or invasive procedures are involved. The findings will inform future implementation of scalable digital rehabilitation models in heart failure management and contribute to health system innovation in chronic disease care.

TELEREHABILITATION-YES (Intervention Group)

Participants will receive a structured 8-week cardiac rehabilitation program conducted entirely at home through a certified telehealth platform (Khymeia VRRS system). The intervention includes real-time supervision by a physiotherapist via videoconferencing, and the use of wearable medical devices for continuous monitoring of vital signs (ECG, heart rate, SpO₂, blood pressure) and motion tracking. Each session includes warm-up, endurance training, and cooldown exercises, with intensity personalized based on baseline cardiopulmonary testing. The platform provides automated data recording, safety alerts, and performance feedback to ensure high-quality remote care. Patients are trained in-person before starting home-based sessions to ensure proper use of the system and adherence to the protocol.

TELEREHABILITATION-YES

Intervention Type BEHAVIORAL

This intervention consists of a structured 8-week cardiac rehabilitation program performed at the patient's home using a certified telemedicine platform. Sessions are delivered in synchronous mode with real-time supervision by a physiotherapist through secure video conferencing. Each session includes warm-up, endurance training, and cooldown exercises, with personalized intensity based on cardiopulmonary exercise testing. Patients are equipped with wearable medical devices for continuous monitoring of vital signs (ECG, heart rate, blood pressure, oxygen saturation) and motion sensors to assess exercise execution and adherence. All data are transmitted securely and stored automatically in the system's database. In addition to the exercise protocol, participants undergo baseline and follow-up assessments including blood biomarkers, echocardiography, cardiopulmonary exercise testing, and quality-of-life questionnaires.

TELEREHABILITATION-NO (Control Group)

Participants in this group will undergo a standard 8-week cardiac rehabilitation program delivered in person at the outpatient facility under direct supervision of a physiotherapist. This group receives face-to-face rehabilitation consisting of individualized exercise sessions performed at the hospital's cardiac rehabilitation unit. Each session includes warm-up, endurance training on a stationary bike, and cooldown, following international guidelines for heart failure patients. Vital signs (heart rate, blood pressure, oxygen saturation) are manually measured and recorded by the physiotherapist, who also administers fatigue and dyspnea scales (Borg and Rate of Perceived Exertion - RPE) throughout the program. No wearable technology is used in this group; monitoring is performed through direct clinical observation and documentation in the medical record.

TELEREHABILITATION-NO

Intervention Type BEHAVIORAL

This intervention involves a traditional 8-week cardiac rehabilitation program carried out at a hospital-based outpatient facility. Patients attend sessions in person under the direct supervision of a physiotherapist. Each session includes warm-up, endurance training using a stationary bike, and cooldown. Vital signs (e.g., heart rate, blood pressure, oxygen saturation) are monitored manually by the physiotherapist, and exercise tolerance is assessed using standardized clinical scales (e.g., Borg and RPE). In addition to the exercise protocol, participants undergo baseline and follow-up assessments including blood biomarkers, echocardiography, cardiopulmonary exercise testing, and validated quality-of-life questionnaires. This group serves as the control for evaluating the effectiveness of the home-based telerehabilitation model.
