目的

对比血管内超声(IUVS)与光学相干断层成像(OCT)指导的急诊经皮冠状动脉介入治疗(PCI)急性心肌梗死的效果。

方法

选择2023年5月至2024年11月武威市人民医院接诊的80例急性心肌梗死患者,其中男性47例,女性33例;年龄51~73岁,平均(63.51±6.59)岁。按照随机数表法分为IUVS组、OCT组,每组40例,IVUS组采用IVUS指导下急诊PCI术,OCT组采用OCT指导下急诊PCI术。比较两组患者术前病变性质检出情况(斑块破裂、斑块侵蚀、脂质及纤维斑块、钙化小结)、术前冠脉情况[最小管腔面积(MLA)、参考血管直径、最小管腔直径、病变长度、分叉病变]、围术期情况(支架置入数、术中扩张次数、支架置入后最小支架面积、支架置入成功率、住院时间)、PCI术后即刻支架置入不良检出率(支架膨胀不良、贴壁不良、即刻血栓、边缘夹层、组织脱垂)、术后30 d主要不良心血管事件(MACE)发生率(心绞痛、再发心肌梗死、恶性心律失常)。

结果

OCT组斑块破裂、斑块侵蚀检出情况高于IVUS组(P<0.05);两组患者MLA、参考血管直径、最小管腔直径、病变长度、分叉病变比较差异无统计学意义(P均>0.05);OCT组术中扩张次数多于IVUS组,住院时间短于IVUS组(P<0.05);OCT组PCI术后即刻支架置入不良总检出率高于IVUS组(P<0.05);两组患者术后30dMACE总发生率差异无统计学意义(P>0.05)。

结论

与IVUS比较,OCT指导急诊PCI治疗急性心肌梗死的患者较好,可有效识别术前病变性质,提高支架不良检出率,缩短住院时间,值得临床推广。

Objective

To compare the effects of intravascular ultrasound (IUVS) and optical coherence tomography (OCT) guided emergency percutaneous coronary intervention (PCI) on acute myocardial infarction.

Methods

A total of 80 patients with acute myocardial infarction admitted to our hospital from May 2023 to November 2024 were divided into IUVS group and OCT group, with 40 cases in each group; there were 47 males and 33 females, the age ranged from 51 to 73 years, with an average of (63.51±6.59) years. Emergency PCI under IVUS guidance was performed in the IVUS group, while emergency PCI under OCT guidance was performed in the OCT group. The preoperative characteristics of lesions (plaque rupture, plaque erosion, lipid and fibrous plaques, and calcified nodules), preoperative coronary conditions [minimum lumen area (MLA), reference vessel diameter, minimum lumen diameter, lesion length, and bifurcation lesion], perioperative situation (number of stent placement, intraoperative dilation times, minimum stent area after stent placement, stent placement success rate, and length of hospital stay), detection rate of immediate stent implantation defects after PCI (stent mal-expansion, poor adhesion, immediate thrombosis, marginal dissection, and tissue prolapse), the incidence of major adverse cardiovascular events (MACE) 30 days after surgery (angina pectoris, recurrent myocardial infarction, and malignant arrhythmias) were compared between the two groups.

Results

The plaque rupture and plaque erosion in OCT group were higher than that in the IVUS group (P<0.05); the MLA, reference vessel diameter, minimum lumen diameter, lesion length and bifurcation lesion were compared between the two groups, with statistically significant (P>0.05); the intraoperative dilation times in OCT group were more than that in IVUS group, and the hospital stay was shorter than that in IVUS group (P<0.05); the total detection rate of stent implantation defects immediately after PCI in OCT group was higher than that in IVUS group (P<0.05); there was no statistical significance in the total incidence of 30dMACE between the two groups (P>0.05).

Conclusion

Compared with IVUS, OCT-guided emergency PCI is better in the treatment of patients with acute myocardial infarction, which can effectively identify the nature of preoperative lesions and improve the detection rate of poor stents, shorten hospital stay, and is worthy of clinical promotion.
