The value of myocardial scanning with 43K was assessed in 64 consecutive patients undergoing coronary arteriography, and in five young volunteers. Myocardial scans at rest detected only 16 of the 35 transmural infarcts documented on electrocardiograms, 11 of 11 anterior infarcts and five of 24 in other sites. Myocardial scans were obtained immediately after a graded exercise test in the five normal volunteers, in nine patients with normal coronary arteriograms and in 25 patients with atherosclerotic narrowing greater than 75% involving the left anterior descending artery, with or without disease of other coronary vessels. All patients with normal coronary arteriograms had normal myocardial scans. A regional perfusion deficit was observed after exercise in all six patients with single vessel disease, but in only 11 of the 19 patients with disease involving two or three vessels. Although the technique was specific, it lacked sensitivity, due mostly to poor resolution and the location of the disease.
对64例连续接受冠状动脉造影的患者以及5名年轻志愿者进行了用⁴³K进行心肌扫描的价值评估。静息心肌扫描仅检测出35例经心电图证实的透壁梗死中的16例，11例前壁梗死中的11例以及其他部位24例中的5例。在5名正常志愿者、9例冠状动脉造影正常的患者以及25例左前降支动脉粥样硬化狭窄大于75%（无论有无其他冠状动脉病变）的患者中，在分级运动试验后立即进行心肌扫描。所有冠状动脉造影正常的患者心肌扫描均正常。在所有6名单支血管病变的患者运动后均观察到局部灌注不足，但在19例两支或三支血管病变的患者中仅11例出现。尽管该技术具有特异性，但由于分辨率差和病变位置的原因，其缺乏敏感性。
