Is slow coronary flow associated with decreased FFR and diffuse atherosclerosis on IVUS?
Slow coronary flow is associated with decreased FFR and diffuse atherosclerosis on IVUS, suggesting it reflects epicardial resistance rather than isolated microvascular dysfunction.
We have demonstrated the decreased FFR in the patients with SCF. Decreased FFR levels have been attributed to increased resistance in the epicardial coronary arteries due to diffuse atherosclerotic disease which has been demonstrated by IVUS.
