Values are expressed as number (percentage) unless otherwise indicated. HR indicates hazard ratio.
Due to reidentification risk, ICES prohibits publication of cell sizes of <6.
Risk stratification: high risk: prior myocardial infarction (MI), unstable angina, or a revascularization procedure (percutaneous coronary intervention or coronary artery bypass grafting); intermediate risk: ≥1 cardiovascular risk factors (eg, dyslipidemia, diabetes mellitus, or hypertension); low risk: no cardiovascular risk factors.
