Exercise Prehabilitation in Congenital Heart Disease (ACE-CHD)
A Randomised-controlled Trial to Assess the Impact of Prehabilitation and a Structured Exercise Programme on Cardiorespiratory Performance in Adults Awaiting Elective Surgery for Congenital Heart Disease: The ACE-CHD Trial.
Around 8-12 in every 1000 babies are born with an abnormal heart, known as a congenital heart defect (CHD). Thanks to major advances in medical and surgical care, most babies born with CHD now live into adulthood.
As people with CHD get older, many need repeated heart operations. We now know from other areas of medicine that "prehabilitation" - a short, structured exercise programme completed before surgery - can improve fitness and help patients cope better with major operations. However, this approach has never been tested in adults with CHD.
We are running a randomised controlled trial to find out whether a prehabilitation programme can improve physical fitness before heart surgery in adults with CHD. Participants will be randomly assigned to usual care or a prehabilitation group. Those in the prehabilitation group will follow a tailored, supervised exercise plan for several weeks before surgery. All patients undergoing cardiac surgery routinely complete a cardiopulmonary exercise test (CPET) as part of their standard pre-operative assessment. CPET is a well-established test that shows how the heart and lungs respond to increasing levels of exercise. During the test, participants exercise on a bike while their breathing, heart rate, and overall physiological response are continuously monitored. The results of each participant's routine CPET will be used to guide the individualised exercise programme in the intervention group. Exercise levels prescribed in the study will not exceed the intensity already safely achieved during the routine CPET, ensuring that activity remains within clinically assessed limits.
Participants in the trial will complete an additional second CPET following the trial period.
Our key question is whether a tailored exercise programme can improve fitness in adults with CHD before heart surgery, and whether this approach is feasible, acceptable and practical to deliver, including successful recruitment and measurable physiological improvements.

Experimentální: Prehabilitation Arm
Participants will undertake a bespoke 6-week prehabilitation programme designed with an exercise physiologist.
The programme is individualised based on CPET results, baseline activity, and patient capability.
It includes cardiovascular, respiratory, and resistance training.
Aerobic exercise is prescribed using a progressive Rating of Perceived Exertion (RPE) approach, targeting 150-300 minutes/week of moderate-intensity activity in line with ESC guidance, with warm-up and cool-down.
Respiratory training is delivered using an inspiratory muscle trainer.
Resistance training targets major muscle groups (15-30 repetitions) using bands, with additional handgrip exercises.
Equipment is provided.
Participants also receive dietary and lifestyle advice with ongoing clinical support.

Participants also receive dietary and lifestyle advice with ongoing clinical support.
Anxiety is addressed by the research team, with referral to psychology if required.
Adherence is supported with at least fortnightly contact (phone/email/text).
All participants undergo repeat CPET at 7-9 weeks.
Participants are encouraged to continue exercises until surgery where feasible.
