Associations between lesion severity and physiological indexes in LAD stenosis warrant prospective validation; leaves open incremental prognostic value.
How do coronary circulatory responses and invasive physiological indexes change according to anatomic and hemodynamic lesion severity in patients with left anterior descending artery stenosis?
This study demonstrates that resting and hyperemic pressure-derived invasive physiological indexes (FFR and iFR) have similar diagnostic accuracy and relationships to anatomic and hemodynamic lesion severity.
Lee et al. (2017) studied this question.
