NCT04114929

Brief Summary

This study evaluates two methods of prescribing exercise intensity in a Phase IV cardiac rehabilitation programme. One method is using specific ventilatory markers and the other following standard care guidelines.

Outcome Measures

Primary Outcomes (1)

  • Peak Oxygen Consumption Change

    Peak Oxygen Consumption as determined by a cardiopulmonary exercise test

    Baseline & 3 months

Secondary Outcomes (1)

  • Health Related Quality of Life Change (EuroQoL EQ-5D)

    Baseline & 3 months

Study Arms (2)

Threshold-Based

EXPERIMENTAL

Patients will be prescribed exercise based on ventilatory thresholds from a maximal cardiopulmonary exercise test

Other: Threshold-based Training

Standard Care

ACTIVE COMPARATOR

Patients will be prescribed exercise based on standard guidelines

Other: Standard Care

Interventions

Specific ventilatory markers determined from a cardiopulmonary test and the correlating heart rate will be used to determine exercise intensity

Threshold-Based

Using the standard care cardiac rehabilitation guidelines exercise will be based on estimated heart rate maximum followed by the karvonan method to calculate 40-70% heart rate reserve

Standard Care
