症候学结合核素心肌灌注显像诊断心肌炎的临床研究

对有心功能损害、心律失常、胸痛及／或心前区紧压感等症候一种以上，且一月内有带咽痛的上呼吸道感染史的患者５６８例，作＾９９ｍＴｃ－ＭＩＢＩ民灌注断层显像。结果表明，有４０４例（７１．２２％）支持临床对心为的诊断。另１０８例患者一月内仅有咽痛的上呼吸道感染史，其中６例（５．５％）其核素心肌灌注显像支持心肌炎，其血清柯萨奇Ｂ组病毒ＩｇＭ抗体呈阳性，诊断搂病毒感染所天才心肌反应，一月后出现心律失常。症候学

Study on combined clinical manifestation and myocardial perfusion imaging with 99mTc-MIBI SPECT for diagnosing myocarditis]

In 568 cases suffering from upper-respiratory tract infection with sore throat and more than one of following clinical manifestations: arrhythmia, heart failure and chest pain or oppressive sensation over the chest(Group A), and another 108 cases without above clinical manifestations(Group B), myocardial perfusion imaging with 99mTc-MIBI SPECT was studied. The results revealed that the imaging in 404 cases (71.12%) of Group A supported diagnosis of myocarditis, but only 6 cases(5.56%) did so in Group B. Because of lacking the clinical manifestations of myocarditis but positive finding of CVB-IgM antibody was detected in their sera, we considered that the positive SPECT imaging in these six cases of Group B belonged to myocardial reaction due to virus infection. It was possible that some of them were suffering from subclinical type of myocarditis.
