Coronary Artery Disease • There has been a steady lowering in CAD mortality rates in Canada associated primarily with decreasing trends in risk factors and improvements in treatment • Despite reduction in smoking, blood pressure, and cholesterol levels, an increase in prevalence of diabetes, lack of exercise, and obesity have been linked with higher CAD mortality Wijeysundera et al JAMA 2011;303:1841-7
ProspeCtive observational LongitudinAl Registry oF patients with stable coronary arterY disease (CLARIFY) • Initiated to improve knowledge about patients with stable CAD from a broader geographic prospective • Main objectives • define contemporary stable CAD outpatients in terms of their demographics characteristics, clinical profiles, management, and outcomes; identify gaps between evidence-based recommendations and treatment; and investigate long-term prognostic determinants in this population Steg Eur Heart J 2009;11(suppl D):D13-D18
Purpose of this Analysis • To • describe the baseline data from the Canadian cohort and compare to the rest of the world (ROW) in CLARIFY in order to provide unique and contemporary insight regarding the characteristics and secondary prevention guideline recommended-management of stable CAD patients
CLARIFY • Prospective, observational, longitudinal registry • Consecutive outpatients with stable CAD from 45 countries in Europe, the Americas, Africa, Middle East, and Asia/Pacific enrolled Nov 2009 – July 2010 • Continued follow-up for 5 years • Collection of standardized data on e-CRF • Complete data audits in 5% randomly selected sites Steg Eur Heart J 2009;11(suppl D):D13-D18
Enrollment criteria • Eligible patients had stable CADdefined as at least one of the following (not mutually exclusive): • Documented MI > 3 months before enrolment • Angiographic demonstration of coronary stenosis > 50% • Chest pain with evidence of myocardial ischemia (stress ECG) • PCI or CABG > 3 months before enrolment • Exclusion crtieria: • Hospital admission for CV reasons (including revascularization) in the past 3 months • Planned revascularization • Conditions hampering the participation or the 5-year follow-up e.g., limited cooperation, limited legal capacity, serious non-CV disease or conditions interfering with life expectancy (e.g. cancer, drug abuse) or severe other CV disease (e.g. advanced HF, severe valve disease, history of valve repair/replacement) Steg Eur Heart J 2009;11(suppl D):D13-D18

Summary • Low number of Canadians met guideline recommended targets for waist circumference, LDL, systolic blood pressure • Canadian cohort compared to ROW • Increased median age, body weight and BMI, more former smokers, increased peripheral arterial disease, increased dyslipidemia • Decreased ischemic stroke, lower median LDL, decreased current angina
Limitations • Recruited physicians and enrolled patients on a voluntary basis, introducing selection bias • The practice of these physicians is likely different from that of all physicians, and we speculate that our participating physicians are more adherent to guidelines compared with physicians who elected not to participate
Conclusion • Stable CAD patients in Canada have many differences with respect to baseline characteristics, duration of CAD, and prior revascularization rates when compared to the rest of the world • More than 1 in 10 continue to smoke and the majority did not meet the secondary prevention targets for waist circumference, body mass index, and physical activity • Further initiatives are needed to promote lifestyle modification in stable CAD patients
