Description of intervention(s) / exposure
Stable CAD or stabilized NSTEMI (ACS) with significant epicardial lesions defined as FFR=0.80. - The PPG Global Registry an investigator-initiated, observational, multicenter study of patients with an indication for PCI based on coronary angiography and FFR =0.80. After confirmation of intention to treat with PCI, a manual pullback with PPG analysis will be performed. A second level of decision making is then performed concerning PCI, coronary artery bypass grafting (CABG) or medical therapy (OMT). Patients will undergo PCI at operator discretion and post-PCI FFR will be measured. Clinical follow-up will be performed at 1, 2 and 3 years.
