26/6/2014· Relationship between IVUS measurements and FFR Several studies have shown good correlation between IVUS measurements and FFR values. In a study of 53 angiographic intermediate coronary lesions, a minimum lumen area (MLA) of ≤ 4.0 mm 2 (by IVUS) was reported to be the best cut-off value in identifying FFR < 0.75, with 92% sensitivity and 56% specificity.

The backbones of the two metal-binding loops adopt conformations capable of metal coordination prior to any calcium-imposed restraints, consistent with both binding sites being occupied. The two extra residues in the helix C region of RasGRP2 relative to RasGRP1 ( Figure 10A ) allow the formation of a short helical turn in EF2, which enables the second metal-binding site to be formed.
