BACKGROUND AND OBJECTIVES The purposes of this study are 1) to investigate the relationship between resting baseline Pd/Pa, determined by the ratio of the pressures proximal (Pa) and distal (Pd) to the target lesion before, inducing hyperemia and fractional flow reserve (FFR) and 2) to identify a resting baseline Pd/Pa range that might reliably preclude the(More)

Previous studies on the incidence and correlation of BBB to clinical factors have produced conflicting results. However, the incidence of BBB was strongly related to age. This study aimed to(More)
