目的研究组织多普勒成像技术与冠状动脉造影在评价冠心病心肌缺血中的应用价值。方法选取86例接受冠状动脉造影检查患者的临床资料,其中冠心病患者46例,冠脉狭窄低于50%的患者40例。所有患者于接受冠状动脉造影后给予组织多普勒成像检查,分析组织多普勒成像技术与冠状动脉造影在评价冠心病心肌缺血中的应用效果。结果 1冠心病患者的二尖瓣血流频谱E/A明显低于对照组,二尖瓣血流频谱A高于对照组,对比存在统计学意义(P<0.05)。2从患者组织多普勒成像技术检出的相关参数上看,ve、va、e/a在二尖瓣环TDI参数、心尖二腔面左室前壁参数、心尖二腔面下壁TDI参数、心尖四腔面左室侧壁TDI参数、心尖四腔面左室间隔壁TDI参数上与对照组存在较大差异,具有统计学意义(P<0.05)。结论利用组织多普勒成像技术,可以将患者左心室早期局部心肌舒张功能异常的情况显示出来,同时可反映缺血最为严重的心肌节段情况,应用价值较高,便于为患者疾病治疗提供依据。
Objective To study the value of tissue Doppler imaging and coronary angiography in the assessment of myocardial ischemia in patients with coronary heart disease. Methods The clinical data of 86 patients who underwent coronary angiography were selected. Among them, 46 patients were coronary heart disease and 40 patients were less than 50% coronary stenosis. All patients underwent coronary angiography after giving tissue Doppler imaging examination, analysis of tissue Doppler imaging and coronary angiography in the evaluation of myocardial ischemia in patients with coronary heart disease. Results 1 The mitral flow spectrum E / A of patients with coronary heart disease was significantly lower than that of the control group. The mitral flow spectrum A was higher than that of the control group (P <0.05). 2 From the parameters of Tissue Doppler imaging, ve, va, e / a showed significant differences in TDI parameters of the mitral annulus, parameters of atrial apical left ventricular anterior wall, There was a significant difference between TDI parameters of apical four-chamber left ventricular wall and TDI parameters of apical four-chamber left ventricular septal wall with the control group (P <0.05). Conclusion Tissue Doppler imaging can be used to show the abnormal local left ventricular diastolic function in the left ventricle. It can also reflect the myocardial segment with the most severe ischemia, which is of high value and convenient for the treatment of the disease .
