| Abstract | 「要旨」虚血唯心疾患62例を対象に運動負荷体位による全身im流分布の差異を検討するために, 臥位または座位エルゴメータを用いて運動負荷タリウム全身シンチを施行した. その結果, (1)虚血性心疾患患者では, 心臓の%Distribution(以下%D)は一過性心筋虚血(以下虚血)の有無, 運動体位, 運動持続時間にほとんど影響を受けず, ほぼ5〜6%を示した. (2)肺および肝臓の%Dは主に運動体位, 運動持続時間, 一過性心筋虚血の有無, 他臓器ことに大腿の%Dに影響を受けると思われた. (3)大腿の%Dは肺, 肝臓の%Dと逆の傾向を示し, 主に運動持続時間, 運動体位に影響を受けると思われた. 以上の結果より, 正常者では重力に抗して交感神経系, muscular pumping actionなどにより臥位および座位運動負荷時に同様な全身血流分布をとるよう調節していると考えられたが, 虚血性心疾患患者では, その調節機序になんらかの破綻をきたして重力の影響がより強く出現していると考えられた. |

| Abstract | [Summary] Whole-body thallium-201 scintigraphy using supine and sitting exercise stress testings were performed to study the fractional distribution of cardiac output of the influences on exercise postures and transient myocardial ischemia in sixty-two patients with ischemic heart diseases. These patients were classified into two groups with and without transient myocardial ischemia by findings of exercise thallium-201 myocardial scintigraphy recorded at the same time. The regions of interest (ROI) were drawn over the whole body and each Organ (heart, lung, liver and thigh), and then, the percent distribution (%D) was calculated in each organ. The %D of heart was little affected by transient ischemia, postures and duration of exercise, and its value was kept to be nearly 5-6% in any condition. The %D of lung and liver were affected by postures, duration of exercise, transient ischemia, and %D of other organs, especially thigh. The %D of thigh was affected by duration of exercise and postures. The %D of thigh showed a reverse tendency to the %D of lung and liver. We conclude that whole-body thallium-201 scintigraphy is a useful means for evaluation of blood flow distribution induced by exercise and posture change. |
