Study Population

The study is based on all patients who underwent diagnostic coronary angiography and were registered in SCAAR during the period 2005 to January 2012 . Only patients who were diagnosed with significant coronary artery disease were included in the analyses.

You may qualify if:

  • Patient with angiographic diagnosis of significant CAD registered in SCAAR between January 2005 and january 2012

You may not qualify if:

  • Previous CABG surgery
  • Missing data on coronary anatomy
  • Patients who underwent a procedure for ACS in whom the 100% occlusion was located in the same coronary artery as the culprit vessel
  • Patients who underwent a procedure in the same vessel within the previous 3 months
