Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

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.
