Description of intervention(s) / exposure
Participants in the SMuRFless CAD Registry will complete a questionnaire at the time of enrolment either electronically on on paper, depending on his or her preference, which is expected to take approximately 15-20 minutes. In addition, information from the participant's SMuRFless CAD clinic visit will be recorded in the registry.

Participants will be invited to provide informed consent for Medicare Benefits Schedule (MBS) / Pharmaceutical Benefits Scheme (PBS) data linkage to assess outcomes at 5-years, including major adverse cardiovascular events (MACE) and changes in medications after the SMuRFless CAD clinic visit.

Participants who return to the SMuRFless CAD clinic for a clinically indicated visit will be invited to complete a questionnaire during this visit for the SMuRFless CAD Registry. This questionnaire can also be completed electronically or by paper form and is expected to take approximately 5-10 minutes.

Summary
Brief summary
The SMuRFless CAD Registry is a study involving patients referred to an National Health & Medical Research Council (NHMRC) Centre for Research Excellence (CRE) for Coronary Artery Disease (CAD) clinic: a specialty clinic of patients with diagnosed or suspected atherosclerotic CAD. The SMuRFless CAD Registry seeks to measure and improve quality of care in SMuRFless CAD patients utilising traditional and applied data linkage methods for key longitudinal endpoints, to determine the clinical and cost effectiveness of the NHMRC CRE clinical pathway in identifying risk factors of CAD progression and to understand risk factors for outcomes and regional/centre differences.
