Clinical Outcomes of Patients With Deferred Revascularization Based on FFR and iFR Negative Coronary Artery Lesions.

The objective is to assess long-term clinical outcomes of patients in whom intervention of coronary lesions was deferred due to negative fractional flow reserve (FFR) and negative Instantaneous wave-free ratio (iFR) in a real-world patient population and to identify factors associated with deferred target lesion failure.
