CLARIFY

(prospecCtive observational LongitudinAl RegIstry oF patients with stable coronary arterY disease)

CLARIFY is an international, prospective, observational, longitudinal registry in stable coronary artery disease (CAD) outpatients with five-year follow-up.  The CLARIFY registry is being undertaken to improve knowledge about the care of outpatients with CAD and 73 cardiologists around Australia were recruited and provided baseline patient data for the registry.  Each cardiologist invited to participate to take part in this registry in Australia was asked to recruit approximately 15 consecutive participants who satisfied the inclusion/exclusion criteria and to follow these participants for up to five years.  The patient population of the CLARIFY registry is intended to reflect the entire international spectrum of outpatients with CAD.

CAD is the major cause of mortality worldwide today and continues to be a major burden on public health.  The ageing population and the ever improving prognosis of coronary patients due to more effective treatments for acute coronary syndrome, revascularisation, and improved prevention, means that an increasing number of patients now live as outpatients, with or without angina symptoms.
