| 目的 探讨冠心病冠脉病变冠状动脉血管内超声(IVUS)表现以及IVUS对冠脉支架置入术的指导价值。方法 选取2016年9月至2017年3月濮阳市安阳地区医院68例冠心病病人,按随机数字表法分为对照组与研究组,各34例。两组均接受IVUS检查,同时对照组经冠状动脉造影(CAG)指导实施冠脉支架置入术,研究组经IVUS指导实施冠脉支架置入术。记录冠心病冠脉病变IVUS表现、治疗前后病变血管最狭窄处直径狭窄率(DS)、斑块负荷以及最小血管直径(MLD)、支架置入率及达标率,并于1年后随访,统计对比两组心脏事件发生率。结果 IVUS检查显示68例病人中8例冠状动脉狭窄程度＞70%,比例11.76%,34例病人最小管腔面积＜4 mm2,比例50.00%,差异有统计学意义(χ2=5.034,P=0.028)；治疗后两组DS、斑块负荷显著降低,MLD显著增加,且研究组DS、斑块负荷显著低于对照组,MLD显著高于对照组,差异有统计学意义(t=4.137,P=0.000；t=10.238,P=0.000；t=10.752,P=0.000)；研究组支架置入率与达标率分别为94.12%与87.50%,显著高于对照组的70.59%与70.83%,差异有统计学意义(χ2=6.476,P=0.011；χ2=5.121,P=0.024)；两组心血管事件发生率比较,研究组(11.76%)与对照组(20.58%)差异无统计学意义(χ2=0.976,P=0.323)。结论 冠心病冠脉病变经IVUS能有效检出,其辅助下开展冠脉支架置入术治疗能够减小斑块负荷,增加血管直径,提升支架置入效果,具有推广价值。 |

| Objective To discuss the performance of coronary intravascular ultrasound (IVUS) in coronary heart disease and the guiding value of IVUS in coronary stenting.Methods Sixty-eight patients with coronary heart disease treated in Anyang District Hospital of Puyang from September 2016 to March 2017 were selected and assigned into the control group and the study group by the random number table method,with 34 cases in each group.Both groups underwent IVUS,and the control group underwent coronary angiography (CAG) to guide coronary stenting.The study group underwent IVUS guidance for coronary stenting.The IVUS manifestations of coronary artery disease in coronary heart disease,the diameter stenosis rate (DS),plaque burden and minimum vessel diameter (MLD),stent placement rate and compliance rate of the most stenotic vessels before and after treatment were recorded and followed up after 1 year.The incidence of cardiac events was compared between the two groups.Results IVUS examination showed that 8 of 68 patients had coronary artery stenosis >70%,the proportion was 11.76%,and the minimum lumen area of 34 patients was <4 mm2,the proportion was 50.00%,and the difference was statistically significant (χ2=5.034,P=0.028);after treatment,DS and plaque load were significantly decreased,MLD was significantly increased,and DS and plaque load in the study group were significantly lower than those in the control group,and MLD was significantly higher than the control group,and the difference was statistically significant (t=4.137,P=0.000;t=10.238,P=0.000;t=10.752,P=0.000);the stent placement rate and compliance rate of the study group were 94.12% and 87.50%,respectively,which were significantly higher than 70.59% and 70.83% of the control group,and the difference was statistically significant (χ2=6.476,P=0.011;χ2=5.121,P=0.024);the incidence of cardiovascular events was different between the study group (11.76%) and the control group (20.58%) with no statistical significance (χ2=0.976,P=0.323).Conclusion Coronary heart disease with coronary artery disease can be effectively detected by IVUS,and coronary stent implantation can reduce the plaque load,increase the diameter of the blood vessel,and enhance the stent placement effect.It has promotional value. |
