Long-term safety of therapy stratification in patients with intermediate coronary lesions based on intracoronary pressure measurements.

Previous studies showed that fractional flow reserve can identify patients with coronary artery disease for whom deferral of an intended percutaneous coronary intervention was more beneficial than perfoming the planned procedure. This study showed that even in symptomatic patients with multivessel disease and intermediate coronary lesions, deferring of patients is a safe option if fractional flow reserve is >0.75.
