CLARIFY is an international, prospective, observational, longitudinal registry – in stable CAD outpatients with 5-year follow-up.

The registry will collect important data on the current status of outpatients with stable CAD:

  • details of patients’ demographic characteristics
  • clinical profiles
  • therapeutic strategies and outcomes.

CLARIFY will involve a minimum of 30,000 outpatients with stable CAD from around 40 countries worldwide, who will be followed for 5 years and data will be collected prospectively at annual visits at 12, 24, 36, 48 and 60 months.

CLARIFY design 01

The first patients were enrolled in October 2009.
These patients will reflect the entire spectrum of outpatients with stable CAD seen by cardiologists and primary care physicians in daily clinical practice as the database will include outpatients with CAD proven by a history of at least one of the following criteria:

  • A documented myocardial infarction which occurred more than 3 months ago
  • A coronary stenosis blocking more than 50% of the artery, as proven by angiography
  • Chest pain with evidence of heart muscle oxygen deprivation (myocardial ischemia) as proven by one of the following diagnostic tests – stress ECG, stress echocardiography, or myocardial imaging
  • A coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI) procedure which was carried out more than 3 months ago.
