~(99m)锝-焦磷酸盐心肌闪烁图的临床意义本文对急性心肌梗塞病人“炸面圈(Dough-nut)”型心肌闪烁图的临床意义进行了探讨。作者研究了45例有“炸面圈”型和26例均匀摄取~(99m)锝-焦磷酸盐心肌闪烁图的病人,共分两组,前者为1组,后者为2组。两组的年龄、性别、心肌梗塞部位和以前的心力衰竭病史都没有明显差别,但以前的心肌梗塞病史,1组更为常见(P<0.05)。两组心肌梗塞重要并发症的发生率,统计学上有显著差异。1组左心衰竭的发生率是67%,2组则为35%(P<0.01)。1组还有梗塞扩展、传导阻滞和死亡率增加的倾向,但和2组之间没有统计学上的意义。1组平均梗塞面积也明显大于2组(47±3.6CM~2对25±2.5CM~2,P<0.001)。梗塞面积和心衰发生率的差别表明:“炸面圈”型闪烁图常比同一区域的均匀型闪烁图
Clinical Significance of ~ (99m) Technetium-Pyrophosphate Myocardial Scintigraphy The paper discusses the clinical significance of “Dough-nut” myocardial perfusion imaging in patients with acute myocardial infarction. The authors studied 45 patients with “donut” type and 26 patients with uniform uptake of 99mTc-pyrophosphate myocardial scintigraphy, divided into two groups, the former one group and the latter two groups. There were no significant differences in age, gender, myocardial infarction, and previous history of heart failure between the two groups, but the previous history of myocardial infarction was more common in group 1 (P <0.05). The incidence of significant complications between the two groups of myocardial infarction, statistically significant differences. The incidence of left ventricular failure in group 1 was 67% and in group 2 was 35% (P <0.01). Group 1 also had an increased propensity for infarct expansion, conduction block, and mortality but not statistically significant with group 2. The average infarct size in group 1 was also significantly greater than that in group 2 (47 ± 3.6 cm -2 vs 25 ± 2.5 cm -2, P <0.001). The difference between the infarct size and the incidence of heart failure indicates that the “donut” scintillation pattern is often better than the uniform scintillation pattern of the same area
