高血压患者^(99m)TC MIBI心肌单光子发射计算机断层显像改变

本文对45例高血压患者作了运动(或潘生丁)和静息■TC-MIBI 心肌 SPECT观察.结果表明:本组患者心肌灌注稀疏缺损(MPD)发生率高达86.7%(39/45);所见 MPD 有运动(或潘生丁)诱发或使之扩大、运动(或潘生丁)显像与静息像一致,前者反而小于后者及二者部位完全不同等多种形式.高血压患者出现上述各种 MPD 的意义尚待进一步研究.

^(99m)Tc-MIBI myocardial SPECT was performed in 45 hypertensive patients.The results showed that:the occurrence of myocardial perfusion defeet (MPD) was 86.7%(39/45) in this group and the MPD could be caused expanded by exercise (or dipyridamole) strees,or the MPD in stress was same as in rest,or the MPD was smaller in strss than in rest,or even the MPDs in stress and in rest were completely different.The significance of MPD found in the hypertensive patients are still to be studied.
