We studied 24 patients with severe coronary artery lesions to assess myocardial perfusion and left ventricular contractile reserve simultaneously using low-dose dobutamine quantitative electrocardiographically gated single-photon emission computed tomography in patients with Kawasaki disease. Low-dose dobutamine infusion was started after an injection of technetium-99m tetrofosmin at rest. Myocardial contractile reserve was evaluated using the post-stress and low-dose dobutamine images, and myocardial perfusion was evaluated using the stress and rest images. Quantitative electrocardiographically gated single-photon emission computed tomography during low-dose dobutamine infusion is a useful and safe method for the combined evaluation of myocardial contractile reserve and myocardial perfusion.
我们研究了24例患有严重冠状动脉病变的患者，以在川崎病患者中使用低剂量多巴酚丁胺定量心电图门控单光子发射计算机断层扫描同时评估心肌灌注和左心室收缩储备。在静息状态下注射锝-99m替曲膦后开始低剂量多巴酚丁胺输注。使用负荷后和低剂量多巴酚丁胺图像评估心肌收缩储备，使用负荷和静息图像评估心肌灌注。低剂量多巴酚丁胺输注期间的定量心电图门控单光子发射计算机断层扫描是联合评估心肌收缩储备和心肌灌注的一种有用且安全的方法。
