目的:研究核素心肌灌注显像在原发性高血压性心脏病心肌缺血诊断中的临床应用价值。方法:110例临床确诊为原发性高血压性心脏病住院患者,进行核素心肌灌注显像及冠状动脉造影检查,分析其心肌缺血、心室功能情况及冠状动脉血流情况,对心肌缺血与冠状动脉血流灌注情况分别进行对比分析。结果:60例表现为可逆性心肌缺血,3例表现为不可逆性心肌缺血,冠状动脉造影结果显示缺血患者中31例阳性显像(血管狭窄程度≥50%),32例阴性显像,且二者缺血严重程度差异无统计学意义(P>0.05)。结论:核素心肌灌注显像可以显示冠状动脉造影阴性的高血压性心脏病患者心肌缺血。
Objective: To study the clinical value of myocardial perfusion imaging in the diagnosis of myocardial ischemia in patients with essential hypertensive heart disease. Methods: One hundred and ten patients diagnosed as hypertensive heart disease were enrolled in this study. Myocardial perfusion imaging and coronary angiography were performed. Myocardial ischemia, ventricular function and coronary blood flow were analyzed. Myocardial ischemia Blood and coronary perfusion were analyzed separately. Results: 60 cases showed reversible myocardial ischemia, 3 cases showed irreversible myocardial ischemia, coronary angiography showed 31 cases of ischemic patients with positive imaging (vascular stenosis ≥ 50%), 32 cases of negative imaging , And there was no significant difference in severity of ischemia between the two groups (P> 0.05). Conclusion: Nuclide myocardial perfusion imaging can show myocardial ischemia in patients with hypertensive heart disease with negative coronary angiography.
