Can a blood flow cuff boost heart rehab?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * All participants must be of legal age (≥18 years) and provide signed informed consent prior to any study procedures * Participants must have a confirmed medical diagnosis of stable cardiac disease (e.g., post-myocardial infarction, stable angina, or post-revascularization) as documented by a specialist. * All subjects must be currently enrolled in or actively participating in a Phase III Cardiac Rehabilitation program (the maintenance phase). * Evidence of clinical stability is required, ensuring that participants can safely perform resistance training without immediate cardiovascular contraindications. Exclusion Criteria: * Unstable Cardiovascular Status: Presence of unstable angina, uncontrolled cardiac arrhythmias, or severe symptomatic aortic stenosis. * Recent Acute Events: Myocardial infarction, coronary artery bypass graft (CABG), or other major cardiac surgeries within the last 3 months (or outside the timeframe defined for Phase III eligibility). * Uncontrolled Hypertension: Resting systolic blood pressure \>160 mmHg or diastolic blood pressure \>100 mmHg despite pharmacological treatment. * Specific Contraindications to BFR: History of deep vein thrombosis (DVT), peripheral vascular disease, or severe lymphedema in the limbs designated for cuff application. * Musculoskeletal Limitations: Any orthopedic or neuromuscular condition that prevents the safe performance of biceps curls or leg press exercises. * Concurrent High-Intensity Training: Participation in any other structured vigorous-intensity exercise program that could confound the results of the intervention. * Medical Instability: Significant comorbid conditions, such as uncontrolled metabolic disease (e.g., Type 2 Diabetes with severe complications), advanced renal failure, or respiratory diseases that limit functional capacity below the study requirements.
