目的观察冠心病患者血管内超声与冠状动脉造影术的差异方法对44例冠心病患者的58处冠脉血管段行冠状动脉造影(CAG)及血管内超声(IVUS)检查。结果对58处冠脉血管段进行IVUS检测和CAG检测。58处血管CAG检测显示均未达到手术干预指征,而IVUS检测显示34处需要进行手术干预治疗。病变血管的直径及直径狭窄率,IVUS和CAG两种检测方法之间的差异有统计学意义(P<0.05)。结论对 CAG检查无明显狭窄者,若患者有明显心肌缺血症状,需进一步行IVUS检查,有助于早期发现冠心病及时采取干预治疗。
Objective To observe the difference between intravascular ultrasound and coronary angiography in coronary heart disease (CHD) patients. Coronary angiography (CAG) and intravascular ultrasound (IVUS) were performed on 58 coronary artery segments in 44 patients with coronary heart disease. Results 58 coronary artery segments were detected by IVUS and CAG. Vascular CAG testing at 58 showed no sign of surgical intervention, whereas IVUS showed 34 requiring surgical intervention. The diameters and stenosis rates of diseased vessels were significantly different between IVUS and CAG (P <0.05). Conclusions There is no obvious stenosis of CAG. If the patient has obvious symptoms of myocardial ischemia, further IVUS examination is needed, which is helpful to detect coronary heart disease early and take timely intervention.
