Abstract
Fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) has shown better clinical outcomes than conventional angiography-guided PCI. The optimal FFR cut-off value for revascularization is debated.
With FFR <_0.80, revascularization for coronary stenosis is associated with improved clinical outcomes, whereas with FFR >_0.75, medical treatment has been shown to result in favorable long-term outcomes. However, there has been controversy over revascularization decision-making for coronary stenosis with FFR between 0.75 and 0.80, the so-called grey zone.
Therefore, in this study, we compared the outcomes of patients after six months from undergoing deferral versus performed percutaneous coronary intervention for coronary stenosis with grey zone FFR (0.75 - 0.80) values, and were included in a non-randomized prospective clinical study.
The main results of the study revealed that:
• The age of the studied group ranged from 38 – 67 years with mean(±SD) of 53.16±7.83 years.
• The studied group included 12 females (24%) and 38 males (76%).
• The mean age of patients undergoing performed PCI is significantly higher than that of those who are undergoing deferred PCI (p-value 0.046).
• There was no significant difference between patients undergoing performed or deferred PCI as regard the risk factors (p-value 0.697).
