目的:探讨核素心肌显像和冠状动脉造影在冠心病诊断中的临床意义,并与平原地区资料相比较,探讨高原地区缺氧环境中核素心肌显像在临床中的应用价值。方法:核素心肌显像:采用单光子发射计算机体层摄影(SPECT),根据充盈缺损部位确定缺血或梗塞部位。冠状动脉造影:采用经右股动脉穿刺,冠状动脉管径狭窄≥50%时判断为冠状动脉造影结果阳性。结果:核素心肌显像对冠心病的诊断敏感性为95.2%,特异性为77.8%,阳性预测值为97.6%,阴性预测值为77.8%。结论:核素心肌显像对冠心病的诊断有较大价值。
Objective: To investigate the clinical significance of radionuclide myocardial imaging and coronary angiography in the diagnosis of coronary heart disease, and to compare the clinical value of radionuclide myocardial imaging in the anoxic environment in the plateau with that in plain areas. Methods: Radionuclide myocardial imaging: Single photon emission computed tomography (SPECT) was used to determine the site of ischemia or infarction based on filling defect sites. Coronary angiography: the right femoral artery puncture, coronary stenosis ≥ 50% judged as coronary angiography positive results. Results: The sensitivity of radionuclide myocardial imaging to coronary heart disease was 95.2%, the specificity was 77.8%, the positive predictive value was 97.6% and the negative predictive value was 77.8%. Conclusion: Radionuclide myocardial imaging has great value in the diagnosis of coronary heart disease.
