Exercise Training in Women With Cardiac Devices (CIED-EX)
December 11, 2023 updated by: Ottawa Heart Institute Research Corporation
The Effects of Exercise Training on Physical and Mental Health in Women With Cardiac Implantable Electronic Devices (CIED-EX): a Pilot Study
Cardiac implantable electronic devices (CIED) are established treatments for a variety of cardiac arrhythmias.
Women with CIED have lower fitness and lower quality of life compared to men with CIED.
Moderate-intensity continuous training (MICT) is the most prescribed exercise for women.
However, high-intensity interval training (HIIT) has been shown to improve fitness, anxiety levels, quality of life, and other health indicators over MICT in men with CIED.
There is a need to quantitatively evaluate the feasibility and effects of a virtual HIIT vs. virtual MICT program on the physical, quality of life, and mental health of women with CIED.
Furthermore, a qualitative approach is also necessary to understand patients' experiences, barriers, and facilitators of a virtual exercise intervention.
This mixed-methods pilot randomized controlled trial will assess the feasibility of a 12-week virtual HIIT and MICT program in women with CIED.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Standard care + moderate-intensity continuous exercise training (MICT)
Supervised virtual MICT exercise sessions for 12 weeks (2x/wk) using the platform Zoom Care.
|
Exercise session: Warm-up: 60-70% peak heart rate (HR) - 10min; Training: 70-85% peak HR - 35min; Cool-down: 60-70% peak HR - 15min.
|
Experimental: Standard care + high-intensity interval training (HIIT)
Supervised virtual HIIT exercise sessions for 12 weeks (2x/wk) using the platform Zoom Care.
|
Warm-up: 60-70% peak heart rate (HR) - 10min; Training: 85-95% peak HR - 25 minutes (4x4-minutes of high-intensity intervals interspersed with 3 minutes of low-intensity intervals); Cool-down: 60-70% peak HR - 10min.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Feasibility - Number of classes participants attended
Time Frame: Week 12
|
Exercise attendance will be assessed by the number of classes participants attended.
High attendance to the CR program will be defined as being present at ≥ 70% of the classes.
|
Week 12
|
Feasibility - Compliance to the exercise prescription based on heart rate
Time Frame: Week 12
|
Exercise compliance will be assessed as the ability to complete the prescribed intensity (based on the heart rate peak [HR] of the cardiopulmonary exercise test) for high-intensity interval training or moderate-intensity continuous training.
The HRs across all classes for each patient will be averaged and compared to their target HR prescription.
For instance, where patients exercised below, within, or above the prescribed HR ranges, these will be coded as "does not comply", "complies" and "exceeds".
|
Week 12
|
Feasibility - Adverse events
Time Frame: Week 12
|
Safety will be assessed by enumerating reported adverse events during the study period.
|
Week 12
|
Feasibility - Number of dropouts
Time Frame: Week 12
|
The number of patients who withdraw from the program will be reported as descriptive data and compared between groups (e.g., high-intensity interval program vs moderate-intensity continuous training).

Quality of life (self-reported)
Time Frame: Baseline
|
will be measured using the 36-Item Short Form Health Survey questionnaire (SF-36).
The SF-36 is a widely used and thoroughly validated, standardized, generic health survey with 36 questions.
It yields an 8-scale (physical functioning; role-physical; bodily pain; general health; vitality; social functioning; role-emotional; and, mental health) profile of functional health and well-being scores as well as psychometrically-based physical (PCS) and mental (MCS) component summary scores.
The PCS has been shown to be one of the most valid SF-36 scales for measuring physical health.
The score ranges from 0 (low) to 100 (high).
The lower the score the more disability.
Higher scores indicate better health status.

Physical activity enjoyment
Time Frame: baseline

the 18-item Physical Activity Enjoyment Scale (PACES) measures the extent (on a 7-point Likert scale) to which participants enjoy doing physical activity by asking participants to rate "how you feel at the moment about the physical activity you have been doing" from 1 (I enjoy it) to 7 (I hate it).
The score ranges from 18-126.
Higher scores indicate higher enjoyment.

|
Participants will complete the Genesis-Praxy questionnaire (20-item).
The gender score is used to categorize patients according to the masculine and feminine characteristics they present (i.e., according to their gender profile).
The score represents the probability between 0% and 100% for each patient to be a "woman."
Therefore, the gender scale is considered a continuum, ranging from masculine characteristics (gender scores toward zero) to feminine traits (gender scores toward one hundred).
This scale does not assess worse or better outcomes.
