潘生丁负荷心肌核素显像诊断冠心病价值的临床分析

The evaluation of the dipyridamole stress 99Tc m-MIBI myocardial perfusion single photone emission computed tomography imaging to forecast the coronary heart disease

目的研究潘生丁负荷心肌核素显像对冠状动脉粥样硬化性心脏病诊断的可靠性。方法选择考虑有冠心病临床表现的64例患者同时行潘生丁负荷心肌核素及冠脉造影检查。结果潘生丁负荷心肌核素显像对诊断冠心病的敏感性为94.4%,特异性为80.0%,阳性诊断价值96.2%,诊断符合率为92.2%。结论潘生丁负荷心肌核素显像检查简便,易行,无创伤性,具有较高的敏感性,对冠心病的诊断有重要价值。

Objective To investigate the reliability of the dipyridamole 99Tc m-MIBI myocardial perfusion single photone emission computed tomography (SPECT) to forecast the coronary heart disease. Method To choose 82 patients with clinical symptom of the coronary heart disease be checked by the dipyridamole 99Tc m-MIBI myocardial perfussion shown and the coronary angiography (CAG). Results The sensitivety in SPECT was 94. 4% and the specificity was 80. 0%. The positive predictive values in coronary heart disease was 96. 2% and the diagnosis rate 92. 2%. Conclusions The dipyridamole 99Tc m-MIBI myocardial perfusion SPECT has a high evaluation to forcast the coronary heart disease, since this examination has a high sensitivity, easy to conduct noninvasive.
