摘要

目的:非顺应性球囊扩张后是改善支架扩张不足的常用策略,但这种策略由于远端栓塞而增加了慢流/无回流(SF/NR)的风险。因此,我们的目的是评估经皮冠状动脉介入治疗(PCI)患者的人口统计学、临床、血管造影和手术特征,这些患者在使用非顺应性(NC)球囊扩张后出现慢流/无再流(SF/NR)。方法:在这项横断面观察性研究中,我们纳入了在首次PCI期间使用NC球囊支架部署后扩张后出现SF/NR的连续患者。评估了人口统计学、临床、血管造影和手术特点。结果:107例患者中,男性占77.6%(83例),平均年龄56.94±10.47岁。胸痛到急诊室的中位时间为292[180-394]分钟。多数患者(66.4%)存在多支血管病变。NC球囊平均长度10.57±1.98 mm,直径3.5±0.26 mm。平均膨胀次数为3.62±1.08次,平均最大压力为20.43±2.49 mmHg,近端压力为19.25±2.74 mmHg,远端压力为14.64±2.01 mmHg。共有5.6%(6)例患者出现不良事件,89.7%(96)例患者最终实现了TIMI(心肌梗死溶栓)III期血流。结论:首次PCI术后扩张后的SF/NR与不良事件发生率和次优(

Clinical Characteristics of Patents who Developed Slow Flow/ no-reflow After Post-dilatation with Non-compliant Balloon during Primary Percutaneous Coronary Intervention
Objectives: Post-dilatation with non-compliant (NC) balloons is a commonly used strategy to improve inadequate stent expansion but this strategy carries an increased risk of slow flow/no-reflow (SF/NR) due to distal embolization. Therefore, our objective was to evaluate the demographic, clinical, angiographic, and procedure characteristics among patients undergoing primary percutaneous coronary intervention (PCI) who developed slow flow/no-reflow (SF/NR) after post-dilatation with non-compliant (NC) balloons. Methodology: In this cross-sectional observational study, we included consecutive patients with SF/NR after post-dilatation using NC balloon post stent deployment during primary PCI. The demographic, clinical, angiographic, and procedure characteristics were evaluated. Results: In the sample of 107 patients, male were 77.6% (83) and mean age was 56.94 ± 10.47 years. The median chest pain to ER (emergency room) arrival time was 292 [180-394] minutes. A majority of the patients (66.4%) had multi-vessel disease. Mean length NC balloon was 10.57±1.98 mm and diameter was 3.5±0.26 mm. The mean number of inflation were 3.62±1.08, at mean maximal pressure of 20.43±2.49 mmHg, proximal edge pressure of 19.25±2.74 mmHg, and distal edge pressure of 14.64±2.01 mmHg. A total of 5.6% (6) patients developed adverse events and final TIMI (thrombolysis in myocardial infarction) III flow was achieved in 89.7% (96) of the patients. Conclusion: SF/NR after post-dilatation during primary PCI is associated with a significant rate of adverse events and sub-optimal (
