Novel Strategies to Improve Cardiometabolic Status and Adherence to Exercise Regimens in Patients at High Risk for Cardiovascular Disease (BURST)

July 24, 2018 updated by: Cambridge Cardiac Care Centre

The Impact of Novel Strategies to Improve Cardiometabolic Status and Adherence to Exercise Regimens in Patients at High Risk for Cardiovascular Disease

This is a 2x2 study examining the impacts of a novel exercise regimen and daily text message reminders in patients at high risk for cardiovascular disease. Patients participating in cardiac rehabilitation will be randomized to either moderate intensity continuous training (MICT) or a novel exercise regimen consisting of three periods of high intensity exercise, called BURST exercise. Additionally, half of the patients in each exercise group will be randomized to receive daily text message reminders to improve adherence to the prescribed exercise regimen.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Numerous studies have demonstrated the important cardiometabolic impacts of high intensity exercise in patients at high risk for cardiovascular disease. It is also known that adherence to exercise regimens is poor within these populations. This study compares the impacts of the current standard of care, moderate intensity continuous training (MICT) to a novel exercise regimen called BURST exercise within a population of patients at high risk for cardiovascular disease. BURST exercise consists of three periods of high intensity physical activity spread throughout the day. Additionally, as mobile technologies continue to be used more to improve adherence to exercise regimens, this study also seeks to compare the impacts of text message reminders in patients prescribed each of the exercise regimens examined in this study. Thus, patients were also randomized to either receive daily text message reminders, or to receive no text message reminders.

Recruitment will be conducted at Cambridge Cardiac Rehab in Ontario, Canada. Potential study subjects are evaluated for inclusion and exclusion criteria, give written informed consent, and are randomized, in a 1:1 ratio, to either MICT or BURST exercise. Additionally, patients are then randomized in a 1:1 ratio to either receive text message reminders or not receive text message reminders.

Patients prescribed the MICT regimen will be asked to exercise for 30 minutes per day at moderate intensity, at least five days per week. Patients prescribed the BURST exercise regimen will be asked to exercise for 10 minutes per session, three times a day at high intensity, at least five days per week. Patients randomized to receive text message reminders will be sent four daily text message reminders reading: "Please remember to exercise for 30 minutes today."

Adherence to exercise regimens will be measured by daily logbooks. Patients are asked to log the times they exercised and for what duration. BRUCE protocol stress tests will be conducted for all patients at baseline (before beginning the study), after three months and after one year. Hemoglobin A1C blood tests, height and weight measurements and lipid profile blood tests will also be conducted at baseline (before the beginning of the study), after three months and after one year.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
