Plain English Summary

Current plain English summary as of 13/02/2019:
Background and study aims
Coronary heart disease (CHD), also known as ischemic heart disease, is one of the leading causes of death worldwide. CHD develops because of the build-up of fatty deposits (plaque) on the walls of the coronary arteries (the arteries that supply the heart with oxygen-rich blood). When arteries are blocked or narrowed, the heart does not receive enough blood to function properly, which can lead to a cardiac event such as a heart attack. After experiencing one cardiac event, the risk of experiencing one again is increased unless there is intensive management of risk factors such as physical activity, smoking, diabetes, hypertension (elevated blood pressure levels), hyperlipidaemia (elevated fat levels in the blood) and obesity. This usually involves being offered a structured education and exercise programme of cardiac rehabilitation, after which risk factor management is done by a GP. The aim of this study is to look at the effectiveness of an education programme with text messaging support for increasing physical activity, specifically walking, in individuals who have had a cardiac event in the past 12 to 48 months.

Who can participate?
Adults who have had a cardiac event 12-48 months ago.

What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group receive usual care, which involves being given general health advices in the form of a standard information leaflet and will be returned to standard care delivered by their GP. Those in the second group also receive the standard information leaflet as well as being invited to take part in two group-based structured education sessions. These education sessions are delivered by trained facilitators approximately two weeks apart. Following this, participants receive regular text messages providing support for a year. Participants in both groups have their physical activity levels assessed at the start of the study and then again after six and 12 months.

What are the possible benefits and risks of participating?
By taking part, both groups will benefit from a health assessment and physical activity advice. Individuals will also receive information on their general fitness levels. Most importantly participants will add to evidence-based lifestyle information that may improve the treatment and support for people 12 months after a cardiac event in the future. During any physical activity there is always an increased risk of a heart event or injury. The walking test is being performed before participants start the study to ensure the risks to an individuals health is very low. These risks are also lowered because the education sessions target the increase of daily physical activity levels rather than vigorous physical activity. There will also be a trained researcher undertaking all aspects of the study. If there are any contraindications individuals will not participate and their GP will be informed. All clinic measurements are carried out by qualified members of the research team. Some people experience minor discomfort and slight bruising during blood tests. A fully qualified research team member will carry out the blood test to ensure any pain is kept to a minimum. If 'abnormal' blood results are found, participant's GPs will be contacted so that they can investigate further.

Scientific titleDeveloping and evaluating an education programme aimed at increasing physical activity in individuals with diagnosed coronary heart disease: a randomised controlled trial
Study hypothesisCurrent study hypothesis as of 13/02/2019:
The aim of the study is to implement an acceptable and cost-effective education programme with text message support and to test the effectiveness of this programme for increasing total daily physical activity, specifically walking activity measured using accelerometry, in individuals 12 to 48 months after diagnosis of a cardiac event.

Previous study hypothesis:
The aim of the study is to implement an acceptable and cost-effective education programme with text message support and to test the effectiveness of this programme for increasing total daily physical activity, specifically walking activity measured using accelerometry, in individuals 12 to 36 months after diagnosis of a cardiac event.
Ethics approval(s)West Midlands - Solihull Research Ethics Committee
ConditionSpecialty: Diabetes, Primary sub-specialty: Both; UKCRC code/ Disease: Cardiovascular/ Other forms of heart disease
InterventionEligible participants will be randomised, apart from those in the same household, using a block design and stratified by gender (men; women), and ethnicity (White European; other) to one of two groups.

Control group: Participants will be provided with general health advice in the form of a British Heart Foundation standard information leaflet and will be returned to standard care delivered by their general practitioner.

Intervention group: Participants will receive the British Heart Foundation standard information leaflet and will be invited to attend two group-based structured education sessions. Theses education sessions will be delivered by trained facilitators approximately two weeks apart and will receive subsequent reinforcement via text message support thereafter (section 3.2). These structured education sessions have been developed and refined in conjunction with PPI work and through the use of existing infrastructure consisting of Diabetes Education and Self-Management in on-going and Newly Diagnosed (DESMOND) groups and a network of trained facilitators. The participants will receive 82 physical activity related text messages at different weekly frequencies following the second education session to the 12 month follow-up assessment.

Participants in both groups will be followed up after 6 and 12 months.
