Протоколы физических упражнений для женщин и мужчин с ИБС (PACED)
Сравнение пиковых значений VO2 протоколов нагрузочных тестов для женщин и мужчин с ИБС
The aim of this study is to determine if the test that allows males to achieve a higher VO2 (a measure of oxygen use during exercise) is different for females. The purpose of this study is to test 4 different exercise testing protocols to compare measured oxygen consumption in females and males with CAD (disease caused by the buildup of plaque in the artery walls which can lead to insufficient amounts of blood, nutrients and oxygen being supplied to the heart). The 4 exercise tests that will be completed on the treadmill are the modified Balke, modified Bruce, modified Naughton and University of Ottawa Heart Institute Slow Ramp protocols. Each test has a different stage duration (the amount of time that the test remains at a pre-determined speed and incline), and incremental increase in speed and incline.
The main purpose of this study is to compare VO2 peak (the maximal amount of oxygen utilized during the exercise test) of females and males with CAD in 4 different exercise protocols. For example, the investigators will find out:
- which exercise protocol is more likely to achieve a higher peak V̇O2 in females and which protocol is more likely to achieve a higher peak V̇O2 in males,
- if enjoyment affects the duration of the test, and
- how different exercise test protocols will provide different results of maximal oxygen used by the participant's body during the exercise test.

Adults older than 18 years of age and have been diagnosed with CAD.
Описание
Inclusion Criteria:
- 18 years and older;
- previous CAD diagnosis by a physician;
- can perform a CPET until volitional exhaustion;
- are able to self-ambulate on a treadmill;
- are at least 8 weeks post cardiovascular event or procedure (i.e., percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG)); and,
- are able to provide written informed consent.
Exclusion Criteria:
- cannot speak, read, write, or understand English or French;
- currently not enrolled in a CR program;

CPETs
Patients will perform all 4 maximal cardiopulmonary exercise tests in randomized order. The protocols they will perform are: Modified Bruce, modified Naughton, modified Balke and the UOHI Slow Ramp. |
Patients will complete 4 different cardiopulmonary exercise tests in random order. |

Первичные показатели результатов
Мера результата |
Мера Описание |
Временное ограничение |
|---|---|---|
|
Oxygen Consumption (VO2)
Временное ограничение: Week 1 to week 4 (measured weekly, at every appointment)
|
V̇O2 will be measured continuously throughout the treadmill CPET. Peak V̇O2, defined as the highest V̇O2 value that is achieved over a 20-s period during the last minute of the CPET. V̇O2 will be measured throughout each test by a metabolic system (Parvo Medics TrueOne 2400). |
Week 1 to week 4 (measured weekly, at every appointment)

Cardiometabolic health indicators - Blood pressure (BP)
Временное ограничение: Week 1 to week 4 (measured weekly, at every appointment)
|
Resting BP (mmHg) will be measured from a seated position using an automated BP monitor. BP will be measured manually using a BP cuff every 2 stages throughout the CPET using an automated BP monitor. Recovery BP will be measured after the completion of the test from a seated position using the automated BP monitor. |
Week 1 to week 4 (measured weekly, at every appointment)
|
|
Cardiometabolic health indicators - Heart Rate (HR)
Временное ограничение: Week 1 to week 4 (measured weekly, at every appointment)
|
Heart rate will be measured from a seated position using an automated BP monitor. HR will be measured continuously throughout the CPET using a 4-lead electrocardiogram connected to a metabolic system. Recovery HR will be measured after the completion of the test from a seated position using the automated BP monitor. |
Week 1 to week 4 (measured weekly, at every appointment)
|
|
Cardiometabolic health indicators - Body mass index
Временное ограничение: Week 1 to week 4 (measured weekly, at every appointment)
|
Height (cm) and body mass (kg) will be measured to compute body mass index (kg/m2). |
