Virtual reality–enhanced multimodal rehabilitation to improve heart and lung fitness after CABG

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized trial will enroll 66 patients in CABG Phase II and assign them by block randomization to three groups: in-clinic multimodal circuit training with VR nature scenes, in-clinic multimodal circuit training without VR, or multimodal circuit training delivered by telerehabilitation. All groups receive weight-bearing Liuzijue Qigong as a baseline component and follow the same circuit-based exercise content. Primary and secondary outcomes include the Dyspnea-12 questionnaire, Cooper 12-minute walk/run test for cardiorespiratory fitness, echocardiographic LVEF, EQ-5D-5L for quality of life, and PSQI for sleep quality. The study compares the added effect of immersive VR and of remote delivery against standard in-clinic multimodal rehabilitation.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Patients who underwent CABG surgery will be recruited after twelve weeks
* Both male and female
* Age 30-60 years old
* LVEF of \< 40%
* Persistent dyspnea with a self-rated intensity of ⩾5 (out of 10) on a visual analogue dyspnea scale (this dyspnea rating was only used as an inclusion criterion and not as a measure for outcome)
* Preserved cognitive function (Montreal Cognitive Assessment score \>24)

Exclusion Criteria:

* Patient with recurrent history of CABG
* Had a non-cardiac surgical procedure ≤2 months prior to recruitment
* Unstable angina, uncontrolled hypertension (blood pressure \>180/100 mmHg), a pacemaker or atrial fibrillation, documented peak orifice area valve stenosis, symptomatic peripheral arterial disease that limits exercise capacity.
* Documented chronic obstructive pulmonary disease (FEV1 \<60% and FVC \<60%)
* Any shoulder impairment that would limit exercise participation
* Patients with Kinesiophobia
* Epilepsy, vertigo, eyesight impairment (conditions contraindicated for VR)
