- Brief Summary
This pragmatic four-arm (1:1:1:1) parallel cluster randomised controlled trial (cRCT) aims to evaluate the effectiveness of reducing the risk of cardiovascular disease (CVD) through three combinations of interventions for individuals at risk of CVD in the primary care setting in Singapore. These interventions are a) communicating an individual's phenotypic risk of CVD, b) a digital psychoeducation application (Heart Age-HOPE-CVD app) that supports health-promoting behavioural change, and c) communicating an individual's genetic risk of CVD. Our study hypothesis is that the exposure of these three interventions will have additive effects on the primary and secondary objectives.
The primary objective of our study is to evaluate the impact of each intervention arm compared to usual care (Arm 1) on the risk for CVD, using change in low-density lipoprotein cholesterol (LDL) measurements as the outcome measure. The secondary objective is to evaluate the impact of each intervention arm compared to usual care (Arm 1) on the following: (a) individual CVD risk factors (i.e. blood pressure, total cholesterol, high-density lipoprotein, body mass index, smoking status, fasting blood glucose or glycated haemoglobin, diagnosis of diabetes, triglycerides level), (b) risk for CVD (i.e., estimated using the Framingham Risk Score), (c) health-related quality of life and well-being, and (d) practice of health-promoting behaviours.
The Heart Age-HOPE-CVD app is a 6-month interventional programme. Hence, the effects of the interventions will be evaluated after a 6-month period. Patients will be recruited by general practitioners (GPs) at primary care clinics around Singapore. After obtaining informed consent at baseline, patients' data will be collected at four time points: baseline, mid-intervention at week 6, post-intervention health screening at week 24 and post-intervention at week 26. All data collection will be conducted at the primary care clinic, except for mid-intervention data which will be collected via an online form.

Group Intervention Description Arm 3: Heart Age and Heart Age-HOPE-CVD app Heart Age-HOPE-CVD App * General practitioners' (GPs) usual care for patients. * GPs will direct patient participants to a publicly available webpage about managing CVD risk on the Health Promotion Board website. * GPs will show patient participants how to access Heart Age, a risk assessment tool available online and communicate with them their respective Heart Age value. * GPs will also direct patient participants to download the Heart Age-HOPE- CVD mobile app, an evidence-based behaviour change digital platform. Arm 4: Heart Age, HOPE-CVD app, and genetic risk communication Heart Age-HOPE-CVD App * General practitioners' (GPs) usual care for patients. * GPs will direct patient participants to a publicly available webpage about managing CVD risk on the Health Promotion Board website. * GPs will show patient participants how to access Heart Age, a risk assessment tool available online and communicate with them their respective Heart Age value. * GPs will direct patient participants to download the Heart Age-HOPE- CVD mobile app, an evidence-based behaviour change digital platform. * Patient participants will undergo genetic testing from which a genetic risk score for CVD will be estimated. They will be informed which quartile of genetic risk they are at in comparison to the rest of the population. The report also contains information on what this risk means for their chances of developing cardiovascular disease in the future. Arm 2: Heart Age only Heart Age * General practitioners' (GPs) usual care for patients. * GPs will direct patient participants to a publicly available webpage about managing CVD risk on the Health Promotion Board website. * GPs will also show patient participants how to access Heart Age, a risk assessment tool available online and communicate with them their respective Heart Age value.

- Primary Outcome Measures
Name Time Method Change in low density lipoprotein Week 0 and Week 24 Low-density lipoprotein cholesterol will be measured and compared between the measurements at baseline and post-intervention health screening.
- Secondary Outcome Measures
Name Time Method Change in triglycerides Week 0 and from Week 24 The triglycerides will be measured and compared between the measurements at baseline and post-intervention health screening visits.
Change in systolic blood pressure Week 0 and from Week 24 Systolic blood pressure will be measured and compared between the measurements at baseline and post-intervention health screening visits.
Change in total cholesterol Week 0 and from Week 24 Total cholesterol will be measured and compared between the measurements at baseline and post-intervention health screening visits.
Change in body mass index Week 0 and from Week 24 Body mass index (BMI) will be compared between the measurements at baseline and post-intervention health screening visits. BMI will be calculated by dividing weight in kilograms and the square of height in metres (kg/m2).
Change in smoking habit Week 0 and from Week 24 Smoking status will be compared between baseline and post-intervention screening visits. The GP will ask the patient participant if she/he is a smoker at the baseline and post-intervention screening visits, and the GP will collect a "Yes" or "No" response.
Change in health-related quality of life Week 0 and from Week 24 Health-related quality of life will be assessed and compared between baseline and post-intervention follow-up visits using the items from the validated instrument "Short Form 36 version 2" (SF-36v2).
Change in 10-year predicted absolute risk of cardiovascular disease Week 0 and from Week 24 Patients' baseline and post-intervention 10-year predicted absolute cardiovascular disease risk will be calculated and compared by a version of the Framingham Risk Score, which is used in the Heart Age algorithm.
The variables (i.e., age, total cholesterol, high-density lipoprotein cholesterol, diabetes prevalence, smoking status, systolic blood pressure, and prescription of anti-hypertensive medications) needed for this algorithm will be measured or obtained at the baseline and post-intervention health screening visits. These variables will be aggregated into a percentage score ranging from 0-100%, where a higher percentage indicates a higher 10-year predicted absolute risk of CVD. A reduction in the percentage score is a better outcome.Change in high-density lipoprotein cholesterol Week 0 and from Week 24 High-density lipoprotein cholesterol will be measured and compared between the measurements at baseline and post-intervention health screening visits.
Change in fasting blood glucose or glycated haemoglobin measurement Week 0 and from Week 24 The fasting blood glucose or glycated haemoglobin will be measured and compared between the measurements at baseline and post-intervention health screening visits.
Change in diagnosis of diabetes Week 0 and from Week 24 The diagnosis of diabetes will be compared between baseline and post-intervention screening visits. The GP will ask the patient participant if she/he is a smoker at the baseline and post-intervention screening visits, and the GP will collect a "Yes" or "No" response.
Changes in health-promoting behaviours Week 0, Week 6, and Week 24 Health-promoting behaviours will be measured using self-reported questionnaires at baseline, 6 weeks, and 6 months to observe changes over the course of the study. This will be measured using the Readiness for Change questionnaire using a scale of 1 to 40, where a higher score indicates a better outcome.
Change in goal-directed behaviours for living well Week 0 and from Week 24 Goal-directed behaviours for living well support a process-based approach to well-being which will be measured and compared between baseline and post-intervention follow-up visits using items in the "EvalUationof goal-diRectedbehaviOurstoPromotewell-beIngandheAlth" scale (Euroia-14). There are 18 items on the Euroia-14 that are separated into four sub-scales (i.e. Self-Affirmation, Social Affiliation, Social Roles and Responsibilities, and Eudemonic). All 18 items are scored between 1 and 4, with a higher score indicating a better outcome.
