心脏康复后运动维持的有效性和经济性 (ECOPCR)

实验性的：运动促进者干预

干预采用小组咨询电话会议 (5)、个人电话联系 (3) 和社区 Heart Wise Exercise 计划演示。

行为的：运动促进者干预

为期 50 周的干预包括 5 次小组咨询电话会议、3 次个人电话和 Heart Wise Exercise 计划演示。 在电话会议和个人电话中，主持人讨论了锻炼的重要性。 参与者回顾他们的活动日记，找出迄今为止经历过的锻炼维护障碍，并集体讨论解决方案。 此外，主持人还在渥太华和多伦多的 Heart Wise Exercise 计划地点为感兴趣的参与者进行社区计划演示。

无干预：日常护理

渥太华大学心脏研究所 Minto 预防与康复中心和大学健康网络心血管康复与预防中心为心脏康复毕业生提供的常规护理。

9-day Accelerometer-measured Physical Activity of Moderate and Vigorous Intensity

Physical activity will be measured directly by having participants wear the Actigraph GT3X accelerometer (Actigraph, Pensacola, Florida) over the right hip for a 9-day recording period, excluding periods when they are sleeping, swimming, or bathing. The activity monitor provides measurements including activity counts, energy expenditure, and step counts, in addition to activity intensity levels. Participants will be considered to be maintaining exercise at guideline recommended levels if they undertake ≥ 30 minutes of moderate and/or vigorous intensity physical activity on ≥ five days. The results report the average minutes of exercise recorded across the full 9 days wearing the accelerometer.

9-day Accelerometer-measured Physical Activity of Moderate and Vigorous Intensity (>/= 10min Sessions)

Physical activity will be measured directly by having participants wear the Actigraph GT3X accelerometer (Actigraph, Pensacola, Florida) over the right hip for a 9-day recording period, excluding periods when they are sleeping, swimming, or bathing. The activity monitor provides measurements including activity counts, energy expenditure, and step counts, in addition to activity intensity levels. Participants will be considered to be maintaining exercise at guideline recommended levels if they undertake ≥ 30 minutes of moderate and/or vigorous intensity physical activity on ≥ five days.

Outcome measure 2 reports the average number of minutes recorded over the full 9 days of wearing the accelerometer, but only when the exercise events last for at least 10 minutes. This differs from Primary Outcome 1 because Primary Outcome 1 is an average of all bouts of exercise regardless of sustained time.

Symptom Limited Graded Exercise Test With Electrocardiographic Monitoring Using a Ramp Protocol on a Treadmill

A random sub-sample of participants will complete a symptom limited graded exercise test with electrocardiographic monitoring using a ramp protocol on a treadmill at baseline and at 52 weeks. Exercise tolerance will also be assessed using the Duke Activity Status Index (DASI), a self-administered questionnaire that measures a patient's functional capacity and is used as an estimate of an individual's peak oxygen uptake

Quality of Life Measured by the the EuroQoL 5D Visual Analogue Scale

The EQ-5D is the current gold standard measure of generic quality of life, has been used in numerous studies and has been validated in many languages. The EQ-5D consists of 2 pages - the EQ-5D descriptive system and the EQ visual analogue scale. The EQ-5D descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The Visual analogue scale ranges from 0-100 with 0 rated as the worst health, and 100 being the best health.

Cardiovascular Risk Factors Measured by Waist Circumference

Waist circumference is measured using a non-stretchable standard tape measure.

Cardiovascular Risk Factors Measured by Systolic Blood Pressure.

Systolic blood pressure is measured in a seated position after a five-minute rest period using an automated, non-invasive blood pressure monitor (BPTru) that automatically performs six measurements. The results represent the average measurements of the six measurements taken.

Cardiovascular Risk Factors Measured by Body Mass Index

Height and weight is measured for the determination of body mass index (BMI).
