OBJECTIVE
To evaluate agreement between instantaneous wave free ratio (iFR) and fractional flow reserve (FFR) for the functional assessment of nonculprit coronary stenoses at staged follow-up after ST-segment elevation myocardial infarction (STEMI).
RESULTS
We measured iFR and FFR at staged follow-up in 112 STEMI patients with 146 nonculprit stenoses. Median interval between STEMI and follow-up was 16 (interquartile range 5-32) days. Agreement between iFR and FFR was 77% < 5 days after STEMI and 86% after ≥ 5 days (p = 0.19). Among cases with disagreement, the proportion of cases with hemodynamically significant iFR and non-significant FFR were different when assessed < 5 days (5 in 8, 63%) versus ≥ 5 days (3 in 15, 20%) after STEMI (p = 0.04). Overall classification agreement between iFR and FFR was comparable to that observed in stable patients. Time interval between STEMI and follow-up evaluation may impact agreement between iFR and FFR.
目的
评估在ST段抬高型心肌梗死（STEMI）分期随访时，瞬时无波比率（iFR）与血流储备分数（FFR）在非罪犯冠状动脉狭窄功能评估中的一致性。
结果
我们对112例患有146处非罪犯狭窄的STEMI患者进行了分期随访，测量了iFR和FFR。STEMI与随访之间的中位间隔时间为16天（四分位间距5 - 32天）。STEMI后<5天时，iFR与FFR的一致性为77%，≥5天时为86%（p = 0.19）。在不一致的病例中，STEMI后<5天（8例中的5例，63%）与≥5天（15例中的3例，20%）评估时，具有血流动力学显著意义的iFR和无显著意义的FFR的病例比例不同（p = 0.04）。iFR与FFR之间的总体分类一致性与稳定患者中观察到的相当。STEMI与随访评估之间的时间间隔可能会影响iFR与FFR之间的一致性。
