Introduction:
Cardiovascular diseases remain the leading cause of mortality worldwide. Despite the proven effectiveness of cardiac rehabilitation (CR) programs, adherence remains unsatisfactory, especially in public healthcare systems such as the Brazilian Unified Health System (Sistema Único de Saúde - SUS), due to logistical, geographical, and socioeconomic barriers. In this context, cardiac telerehabilitation (CTR) has emerged as a promising alternative, with effectiveness comparable to traditional center-based cardiac rehabilitation.
However, evidence regarding hybrid cardiac telerehabilitation models applicable to the Brazilian context, using simple and low-cost technologies, remains scarce.
Objectives:
To investigate adherence and its effects on the effectiveness, safety, and maintenance of exercise practice across different models of cardiac rehabilitation, with emphasis on the development and implementation of a hybrid cardiac telerehabilitation (HCTR) model adapted to the Brazilian context.
The primary outcome will be adherence to the exercise program, defined as participation in at least 75% of the proposed sessions during the 12-week intervention.
Secondary outcomes will include estimated cardiorespiratory fitness, functional capacity, functional mobility, handgrip strength, and health-related quality of life.
Adverse events, digital health literacy, exercise maintenance, hospitalizations, and benefits and barriers to exercise will be evaluated as exploratory variables.
Methods:
This is a pragmatic, single-center, three-arm parallel randomized clinical trial consisting of hybrid cardiac telerehabilitation (HCTR), traditional center-based cardiac rehabilitation (TCR), and a usual care (UC) group.
A total of 219 participants with coronary artery disease, with or without acute coronary syndrome, and/or stable heart failure, who are eligible for Phase II cardiac rehabilitation and receiving care through the Brazilian Unified Health System (Sistema Único de Saúde - SUS), will be enrolled.All participants will undergo standardized clinical and functional assessments at baseline, post-intervention, and short-term follow-up.
Clinical screening and exercise stress testing will be performed at the Santa Catarina Institute of Cardiology (Instituto de Cardiologia de Santa Catarina - ICSC), whereas physical assessments and interventions will be conducted at the Center for Cardio-Oncology and Exercise Medicine (Núcleo de Cardio-Oncologia e Medicina do ExercÃcio - NCME), State University of Santa Catarina (UDESC).
The intervention will last 12 weeks, followed by an additional 12-week short-term follow-up period.
Participants allocated to the HCTR group will receive a hybrid intervention consisting of face-to-face sessions, synchronous sessions supervised through videoconferencing, and remotely monitored asynchronous activities.
Participants in the TCR group will participate exclusively in supervised face-to-face sessions, whereas participants in the UC group will receive usual clinical care, including conventional clinical guidance and an educational booklet.
Study Significance:
This clinical trial aims to generate evidence regarding adherence, effectiveness, safety, and maintenance of exercise practice across different models of cardiac rehabilitation. Furthermore, it seeks to provide evidence to support the development and implementation of a hybrid cardiac telerehabilitation model adapted to the Brazilian context and the Brazilian Unified Health System (SUS), contributing to expanding access to cardiac rehabilitation through accessible digital technologies.

Participants assigned to this arm will undergo a 12-week hybrid cardiac telerehabilitation program consisting of in-person sessions, synchronous activities supervised by videoconference, and asynchronous activities remotely monitored, according to the structured exercise protocol developed for this study.
Participants assigned to this arm will undergo a 12-week supervised traditional center-based cardiac rehabilitation program at the Center for Cardiology and Exercise Medicine (NCME/UDESC), according to institutional organization and service availability, following the structured exercise protocol developed for this study.
Participants assigned to this arm will remain under usual clinical care for 12 weeks, receiving standard clinical guidance and an educational booklet on the safe practice of physical exercise developed specifically for this study. The educational booklet is intended to standardize the guidance provided to participants, promote the safe practice of physical exercise, and ensure a minimum level of care throughout the study period. If clinically indicated, participants may be referred to the center-based cardiac rehabilitation program during or after the study period, subject to service availability and the participant's willingness to participate.
