心臓リハビリテーション後の運動維持の有効性と経済性 (ECOPCR)

実験的：運動ファシリテーターの介入

この介入では、小グループのカウンセリング電話会議 (5 件)、個人的な電話連絡 (3 件)、およびコミュニティでのハートワイズエクササイズプログラムのデモンストレーションが採用されています。

行動：運動ファシリテーターの介入

50週間の介入には、5回の小グループカウンセリング電話会議、3回の個人電話、ハートワイズエクササイズプログラムのデモンストレーションが含まれます。 電話会議や個人的な電話で、ファシリテーターは運動の重要性について話し合います。 参加者は自分の活動日誌を確認し、これまでに経験した運動維持の障壁を特定し、グループとして解決策をブレインストーミングします。 さらに、ファシリテーターは、オタワとトロントにあるハート ワイズ エクササイズ プログラムの場所で、関心のある参加者向けにコミュニティ プログラムのデモンストレーションを実施します。

介入なし：普段のお手入れ

心臓リハビリテーションの卒業生に対する通常のケアは、オタワ大学心臓研究所ミント予防・リハビリテーション・センターおよび大学医療ネットワークの心臓血管リハビリテーション・予防センターによって提供されます。

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).
