The Health Impact of High Intensity Exercise Training With Intervals During Cardiac Rehabilitation
Heart Disease, Heart Attacks
About this trial
This is an interventional treatment trial for Heart Disease focused on measuring High intensity Interval Exercise training, Cardiac rehabilitation, cardiac revascularisation, Percutaneous coronary interventions, Cardiac surgery
Eligibility Criteria
Inclusion Criteria:
- History of acute coronary syndromes, had a recent revascularization procedure
- History of stable heart failure or stable angina.
Exclusion Criteria:
- Unstable angina
- Systolic blood pressure of >200 mm Hg, or diastolic blood pressure >110 mm Hg (should be assessed on a case-by-case basis)
- Orthostatic blood pressure drop of >20 mm Hg with symptoms
- May have had the implantation of cardiac defibrillators (ICD)
- Synchronization devices or ventricular assist devices
- Have had a heart valve repair/replacement, a heart transplant, or grown-up congenital heart disease, critical aortic stenosis, acute systemic illness or fever, -
- Uncontrolled atrial or ventricular arrhythmias, acute pericarditis or myocarditis
- Recent embolism, thrombophlebitis, resting S-T segment depression (>2 mm), uncontrolled diabetes (should be assessed in accordance with local protocol and on a case-by-case basis)
- Severe orthopedic conditions that would prohibit exercise
- Other metabolic conditions, such as acute thyroiditis, hypokalemia or hyperkalemia, hypovolemia, severe rejection (cardiac transplant recipients), triple A >4.5 cm (if under surveillance will need confirmation from vascular surgeon as long as blood pressure remains stable)
- Tachycardia >100 beats per minute at rest, or cataracts (may commence exercise after 6 weeks)
Sites / Locations
- Liverpool Heart and Chest Hospital

Experimental
Active Comparator
High intensity interval training (HIIT)
Standard Care
Patients will undergo a 15-minute warm-up, followed by a 24-minute conditioning phase, and a 10-minute cool-down. The conditioning phase will include a combination of aerobic exercise (e.g. cycling or walking) and resistance exercise (e.g. squats, bicep curls). Patients will complete 5 intervals of 3 minutes with 2 minute rest periods interspersed. The intensity will correspond to 16-17 on the Borg 6-20 Rating of perceived exertion scale. Patients will exercise once a week for 8 weeks.
Patients assigned to this group will participate in usual standard care of cardiac rehabilitation. Commonly, patients will undergo a 15-minute warm-up, followed by a 24-minute conditioning phase, and a 10-minute cool-down. The conditioning phase will include a combination of aerobic exercise (e.g. cycling or walking) and resistance exercise (e.g. squats, bicep curls). Patients will complete 5 intervals of 3 minutes with 2 minute rest periods interspersed. The intensity will correspond to 11-15 on the Borg 6-20 Rating of perceived exertion scale. Patients will exercise once a week for 8 weeks.
