It aims to compare the effects of a professional -led support programme using a mobile application versus telephone advice on clients at risk of coronary heart disease. A multi-centre, single-blinded, randomized controlled trial will be conducted. 168 Clients who are at risk of coronary heart disease (CHD), able to use a smart phone will be randomized into the App Support group (App group) or the Nursing Telephone advice (NTA) group . All participants will receive same nursing educational briefing related to CHD. The App Group will additional receive an app use to support their self care whereas the NTA group will receive nursing telephone advice for 20 minutes monthly.
Health outcomes will be collected at baseline (T0), 1 months (T1), 3 months (T2). Data analysis will be conducted using a Generalized Estimating Equations model to assess differential changes in all outcome variables.
The aim of this study is to test the effects of a professional-led support programme for clients who are at risk of developing CHD on outcomes of total exercise, self-efficacy and self-management behavior, emergency department attendance and hospitalizations, CHD risk factor profile, and quality of life.
Over 3 months, the investigators will examine the effect on the App group as compared to the NTA group and the control group of: Total amount of exercise (primary outcome) and secondary outcomes:1) Self-efficacy and self-management behavior; 2)Emergency department attendance and hospitalization frequency;3) CHD risk factor profile (smoking, blood pressure, body mass index, blood lipid level);4) Cardiovascular functional endurance;5)Perceived stress ; and 6) Quality of life.
A prospective multi-Centre, parallel, randomized controlled trial (RCT) with two arms - an app support programme (App) group vs a Nursing Telephone advice (NTA) group and a control group - will be adopted. The RCT method follow CONSORT 2010 guideline. 168 subjects will be required (n=84 each group). Subject recruitment will likely take about 14 months.
Intervention protocol: 168 Clients who are at risk of coronary heart disease (CHD), able to use a smart phone will be randomized into the App Support group (App group) or the Nursing Telephone advice (NTA) group. All eligible participants will receive same nursing educational briefing related to CHD. The App Group will additionally receive an app use to support their self -care whereas the NTA group will receive a leaflet and a monthly nursing telephone advice ( about 20 minutes per call. The duration of intervention will be about 3 months. Health outcomes will be collected by research assistant at baseline (T0), 1 months (T1), 3 months (T2) at the community Centre or research Centre. Data analysis will be conducted using SPSS and a Generalized Estimating Equations model to assess differential changes in all outcome variables. All the tests will be two-sided and a p-value of <0.05 will be considered statistically significant.
Ethical approval and permission will be sought from the study university and the selected community centres. RCT registration has been obtained from the ClinicalTrials.gov Protocol Registration system (https://clinicaltrials.gov/).

To minimize subject contamination, the different groups will be assigned different follow-up dates. The research assistants who are responsible for collecting data will be blinded to the group allocations. To ensure allocation concealment, each computer generated sequence will be put in a sequentially numbered, opaque sealed envelope. The envelope will be opened by RA1 after the participant has completed the baseline questionnaire.

| Nursing telephone advice (NTA) group | Device | All subjects will continue their usual care with prescribed medical treatments and follow-ups if any. By appointment, a trained nurse will provide a health talk related to the CHD care. In addition to the above usual care, three monthly 20-minute telephone follow-ups supplemented by take home leaflet will be provided by a trained research nurse for up to 3 months. Patients can ask about their related health problems, if any. The team has set up a telephone advice guide to support the research nurse in giving phone advice and text messages. .In summary, all two groups will receive from a nurse similar educational content as that related to their CHD and care. The only difference will be the re-enforcement and continual support provided through an app, telephone nursing advice and leaflet. |

| Change of blood pressure | systolic and distolic pressure will be collected by research assistant | baseline, 3 months |
| Change of cardiovascular endurance test | Three-minute step test aims to test the client's cardiovascular functional endurance after exercise across the age span and gender. A participant step on and off of a 12-inch high bench/ or stair for 3 minutes. Their pulse is then taken while the participant remains standing. Compare the heart rate with the table according to the age and gender to determine the fitness within a range of 7 scores from excellent to good, above average, average, below average, poor and very poor. | baseline, 3 months |
| Change of total physical exercise | This outcome will be measured using the Godin-Shepherd Leisure Time Physical Activity Questionnaire. This scale measures how often per week and how long per session the respondent has performed strenuous, moderate and mild exercise outside of their work duties. | baseline, 3 months |
| Change of perceived stress scale (PSS-10) | 10 self-reported items are used to measure the degree to which situation in a person's life are considered stressful, as well as the current levels of stress experienced in the last month. The summative scores range from 0 to 40, with higher scores indicating higher stress levels. These scores have been used previously to assess the experienced level of stress as an outcome measure and have good psychometric properties in cardiac patients. | baseline, 3 months |
| Change of Quality of Life:ED-5D | The ED-5D is a generic instrument used to measure the quality of life in patients with cardiovascular disease in Chinese and other populations. These scale is divided into 5 parts: mobility, self-care, usual activities, pain/discomfort and anxiety/ depression. Participants are asked to respond to the items using the following options: no problem, moderate problems, and extreme problems. The 5 items will also be ranked on a visual analogue scale (VAS) with a range with points from 0 (worst possible health) to 100 (best possible health) to assess the patient's health. The ED-5D was found to be satisfactorily valid and reliable in many populations, including CHD patients. | baseline, 3 months |
| Hospitalization frequency | frequency of hospitalization will be asked. | 3 months |
| change of body weight | body weight will be measured by RA | baseline, 3 months |
| change in LDL cholesterol | Blood samples for measuring LDL cholesterol will be taken by using a finger stick using auto-analysed and the participants are asked to have 8 hours fasting. | baseline, 3 months |
| Change in HDL cholestero | Blood samples for measuring HDL cholesterol will be taken by using a finger stick using auto-analysed and the participants are asked to have 8 hours fasting. | baseline, 3 months |
