Luminal renarrowing after successful coronary angioplasty is now recognised as a continuously distributed process which is determined largely by the extent of luminal increase achieved at angioplasty. In this study an alternative analytical approach is applied to determine whether luminal renarrowing following coronary intervention is related to the mechanism of luminal increase (ie by balloon, by atherectomy, by a self-expanding stainless steel mesh stent, or by a balloon-expandable tantalum coil stent). The results confirm the known proportional relationship between luminal renarrowing during follow-up and luminal improvement at intervention, regardless of the device used. However, significant differences were observed between the devices, which may reflect device-specific characteristics of the hyperplastic response to vessel injury and may have clinical implications.
成功进行冠状动脉血管成形术后管腔再狭窄现在被认为是一个连续分布的过程,这在很大程度上取决于血管成形术时管腔增加的程度。在本研究中,应用了一种替代分析方法来确定冠状动脉介入治疗后的管腔再狭窄是否与管腔增加的机制有关(即通过球囊、旋切术、自膨胀不锈钢网支架或球囊扩张钽线圈支架)。结果证实了随访期间管腔再狭窄与介入时管腔改善之间已知的比例关系,无论使用何种装置。然而,不同装置之间观察到显著差异,这可能反映了对血管损伤的增生反应的装置特异性特征,并且可能具有临床意义。
