A Study to Compare the Effectiveness of Different High-intensity Interval Training Programs in Cardiac Rehabilitation

Overview

About this study

The main purpose of the study is to examine the effect of two different high intensity interval training (HIIT) prescription approaches on improving fitness, heart function, and the ability of the body's muscles to receive oxygen. The two approaches of the same total exercise durston will include: 1) HIIT with progressively increased interval durations (PRO-HIIT) versus 2) HIIT with constant shorter interval durations (CON-HIIT). The study hypothesis is that the progressively increased interval duration at high-intensity (PRO-HIIT) will result in a greater increases in fitness, heart function, and the ability of the body's muscles to receive oxygen in patients enrolled in cardiac rehabilitation. 

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Adult 18 years and older.
  • English speaking.
  • Able to provide consent.
  • Has a qualifying indication for center-based cardiac rehabilitation that is non-surgical (i.e., Acute coronary syndrome, myocardial infarction, percutaneous coronary intervention, and stable angina).

Exclusion Criteria: 

  • Participants referred to cardiac rehabilitation following coronary artery bypass surgery, heart valve repair/replacement, heart transplant, or those with ventricular assist devices.
  • Patients who are unable to engage in a regularly structured exercise training program as part of a clinically indicated center-based outpatient cardiac rehabilitation program are not eligible.
  • Patient unable/unwilling to provide informed consent will not be enrolled.
  • Contraindication to maximal exercise testing or high intensity exercise training
  • Suboptimal echocardiogram image quality
