Brief summary

To assess whether incorporation of a polygenic risk score (PRS) into cardiovascular disease examinations (e.g., Heart Health Check), through the PPP-CAD clinical pathway, identifies subclinical CAD in participants considered to be at low or moderate 5-year absolute cardiovascular disease (CVD) risk (Absolute CVD Risk).

Interventions

ESCALATE study participants will undergo a cardiovascular disease (CVD) risk assessment with their general practitioner (GP), lasting approximately 1 hour and utilising the Partnership for Precision Prevention in Coronary Artery Disease (PPP-CAD) clinical pathway. Participants will complete a questionnaire at the time of enrolment, which is expected to take approximately 15 minutes. A 5-year "absolute risk score" will be calculated for all participants, utilising the risk calculator provided b

ESCALATE study participants will undergo a cardiovascular disease (CVD) risk assessment with their general practitioner (GP), lasting approximately 1 hour and utilising the Partnership for Precision Prevention in Coronary Artery Disease (PPP-CAD) clinical pathway. Participants will complete a questionnaire at the time of enrolment, which is expected to take approximately 15 minutes. A 5-year "absolute risk score" will be calculated for all participants, utilising the risk calculator provided by the National Vascular Disease Prevention Alliance (www.CVDcheck.org.au). Participants considered High Risk of a CVD event within the next five years will not need to complete the rest of the clinical pathway; the GP will discuss his or her treatment recommendations with the participant. Participants who are considered to be low- or moderate-risk from this risk calculator will undergo a polygenic risk score (PRS) for CAD from Allelica. Participants with a PRS less than 80% will not need to complete the rest of the clinical pathway; the GP will discuss his or her treatment recommendations with the participant. Participants with a PRS of 80% or greater will be referred for a CT scan of the heart to calculate a coronary artery calcium score (CACS), which will involve attendance at a local imaging centre working with the study. The CT scan usually takes about 5 to 10 seconds and there are no injections required as part of this scan. The GP will use all the information from the heart disease assessment and CAC score (as available) to discuss his or her treatment recommendations with the participant. At the end of the PPP-CAD clinical pathway, participants will complete a questionnaire about their experience of a CVD examination utilising the PPP-CAD clinical pathway. Participants will complete a second questionnaire 6-months after their first visit with their GP. This questionnaire will ask participants about events occurring since the last visit, new diagnoses, and new medications he or she may be taking. Participants will return to their GP for a final visit 12-months after their first study visit. During this visit, the participant will complete a questionnaire, which should take approximately 15 minutes.
