为观察硝苯吡啶对９９ｍＴｃ－ＭＩＢＩ心肌断层显像的影响，把３５例冠心病患者分成硝苯毗啶组和硝酸甘油组，隔日行介入心肌断层显像，静注９９ｍＴｃ－ＭＩＢＩ后１ｈ和５ｈ时分别采集图象，分析结果显示硝苯毗啶组虽有４０．０％的心肌节段摄取较用药前改善，但１ｈ显像有３３个节段出现逆向性摄取减少，其中２９个节段５ｈ显像又恢复正常。硝酸甘油组有６９．５％心肌节段较用药前摄取改善， １ｈ显像未见有逆向性摄取减少。说明硝苯吡啶介入９９ｍＴｃ－ＭＩＢＩ心肌断层显像部分心肌有一过性的摄取减少。如何解释有待进一步研究。
To observe the effect of nifedipine on 99mTc-MIBI myocardial imaging, 35 patients with coronary heart disease were divided into nifedipine group and nitroglycerin group. The myocardial infarction was performed on the next day, 1h and 5h after intravenous injection of 99mTc-MIBI At the same time, 40 cases of nifedipine group had improved myocardial segment intake compared with that before treatment, but 33 segments of 1h imaging showed a decrease of reverse intake, of which 29 segments 5h imaging returned to normal. In the nitroglycerin group, 69.5% of myocardial segments improved compared with those before treatment, and no adverse effects were found in 1h imaging. Description nifedipine interventional myocardial 99mTc-MIBI myocardial imaging had a transient decrease in myocardial uptake. How to explain for further study.
