Angiograms were performed by standard technique via radial or femoral approach. Obstructive CAD was primarily defined as stenosis >50% in any major epicardial coronary artery, but the alternative stenosis cutoff of >70% was also assessed. Left main trunk with at least 50% stenosis was always considered as >70% CAD. Invasive coronary angiography wad graded by visual inspection of the cath-lab physician performing the diagnostic procedure.
