To evaluate the effect of stent boost subtract (SBS) imaging on stent underexpansion during percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI) by optical coherence tomography (OCT).
One hundred thirty-eight STEMI patients who underwent drug-eluting stent (DES) implantation were prospectively recruited and divided into the SBS group (69 cases) and the CAG group (69 cases) according to whether SBS was used to guide PCI. Finally, OCT was performed on all enrolled patients, and the OCT results were used as the gold standard to evaluate the impact of standard SBS technology on stent underexpansion immediately after DES implantation.
SBS identified 51 patients (24%) with stent underexpansion while OCT identified 56 patients (27.2%). SBS has a sensitivity of 80%, a specificity of 96%, a positive predictive value of 88%, and a negative predictive value of 93% for identifying stent underexpansion.
Compared with OCT, SBS technology is a rapid stent imaging evaluation method that can accurately quantify the stent expansion level and is time-saving and economical.
通过光学相干断层扫描（OCT）评估急性 ST 段抬高型心肌梗死（STEMI）患者经皮冠状动脉介入治疗（PCI）中支架扩张不足的支架增强减影（SBS）成像效果。
前瞻性招募了 138 例接受药物洗脱支架（DES）植入的 STEMI 患者，并根据是否使用 SBS 指导 PCI 将其分为 SBS 组（69 例）和 CAG 组（69 例）。最终，对所有纳入的患者进行 OCT 检查，并将 OCT 结果作为金标准，评估标准 SBS 技术对 DES 植入后即刻支架扩张不足的影响。
SBS 识别出 51 例（24%）支架扩张不足的患者，而 OCT 识别出 56 例（27.2%）。SBS 识别支架扩张不足的敏感度为 80%，特异度为 96%，阳性预测值为 88%，阴性预测值为 93%。
与 OCT 相比，SBS 技术是一种快速的支架成像评估方法，可以准确地定量评估支架扩张程度，省时且经济。
