Adherence
Using peak exercise indices (e.g., %VO2peak, %HRpeak) to prescribe exercise intensity in CVD patients is unreliable and should be replaced by threshold-based methods (VT1, VT2) determined via Cardiopulmonary Exercise Testing (CPET).
Do not rely on 'percentage of max heart rate' to guide your exercise. This number is often inaccurate for heart patients. Instead, undergo a Cardiopulmonary Exercise Test (CPET) to find your Ventilatory Thresholds (VT1 and VT2). Train between these thresholds. This ensures you are working hard enough to benefit, but not so hard that you are unsafe. Re-test if your fitness improves significantly.
An important problem associated with using these indices of peak exercise capacity for exercise prescription is that not all CVD patients achieve a (near-) maximal effort during CPET... There is considerable inconsistency between indicators derived from peak exercise parameters in CVD patients, highlighting the need for standardization and adjustment of the current guidelines.
Why this rating
Based on multiple studies showing inconsistencies and failure to achieve maximal effort in CVD patients.

More from this paper
- High-intensity interval training (HIIT) produces greater improvements in peak oxygen uptake (VO2peak) compared to moderate-intensity continuous training (MICT) in patients with coronary artery disease (CAD) and heart failure with reduced ejection fraction (HFrEF), primarily due to greater metabolic stress and mitochondrial biogenesis.Good
- Total energy expenditure (volume) is a stronger predictor of improvements in exercise capacity and health parameters than exercise intensity alone; therefore, prescribing exercise based on total energy expenditure is more effective than focusing solely on intensity.Good
