Fourteen patients with transmural myocardial infarction were studied by gated cardiac blood pool scanning (to determine regional ventricular function) and 43-K myocardial imaging (to determine the regional distribution of myocardial perfusion). An akinetic area on the gated scan and an area of decreased tracer concentration on the 43-K image were detected. The area of reduced 43-K concentration averaged 33.5% of the left ventricular circumference which correlated (r = 0.74, p less than 0.01) with the area of infarction determined by the zone of akinesis, 34.2% of left ventricular circumference. The extent of akinesis and left ventricular ejection fraction were significantly different in those patients with left ventricular failure than in those without failure.
对14例透壁性心肌梗死患者进行了门控心血池扫描(以确定局部心室功能)和43-K心肌显像(以确定心肌灌注的局部分布)研究。在门控扫描中检测到运动不能区,在43-K图像上检测到示踪剂浓度降低区。43-K浓度降低区平均占左心室周长的33.5%,与由运动不能区确定的梗死面积(占左心室周长的34.2%)相关(r = 0.74,p<0.01)。有左心室衰竭的患者与无左心室衰竭的患者相比,运动不能的程度和左心室射血分数有显著差异。
