Prehab2Rehab is a prospective single-arm feasibility study evaluating the implementation of a multimodal, digitally supported prehabilitation program for adults awaiting elective cardiac surgery. During the routine preoperative waiting period, participants receive individualized education, psychosocial support, nutritional counselling, home-based physical activity guidance, and digital self-management support. The study aims to determine the feasibility, acceptability, usability, and safety of integrating this multidisciplinary prehabilitation pathway into routine clinical care. Exploratory outcomes include functional capacity, psychological well-being, nutritional status, digital engagement, and selected perioperative clinical outcomes to inform the design of future confirmatory trials.
Classification as New York Heart Association (NYHA) functional class I-II
Low surgical risk profile, defined as a EuroSCORE between 0 and 3
Open-heart valve surgery
Coronary artery bypass grafting (CABG)
Emergency, urgent, or otherwise non-elective cardiac surgery
Highly complex or specialized surgical procedures (e.g., aortic aneurysm repair, cardiac tumor resections)
Interventional cardiac procedures (e.g., transcatheter aortic valve implantation [TAVI], MitraClip interventions)
Neuromotor or physical impairments that might prevent adherence to the study protocol or informed participation
Single group
Digitally supported prehabilitation program
Other interventionThe Prehab2Rehab intervention is a personalized, multimodal, digitally supported prehabilitation program delivered during the routine 6-10 week preoperative waiting period before elective cardiac surgery. The program includes structured patient education, psychosocial support, nutritional assessment and counselling, individualized home-based physical activity guidance (including aerobic exercise, resistance training, breathing exercises, and inspiratory muscle training), and digital tools to support education, communication, self-management, and documentation. The intervention is delivered by a multidisciplinary team and complements routine perioperative care without altering standard clinical management.
