Abstract | 「要旨」閉塞性動脈硬化症, 大動脈瘤等, 通常の運動が困難な症例におけるdipyridamole負荷心筋シンチグラフィの有用性について, arm-ergometer, 坐位ergometerと比較検討した. 心筋シンチグラム上正常像を示した56例を対象に, 血圧, 心拍数, end-point等の検査時所見, 201Tlの肺野への取り込み, washout rate, 心筋/background比を対比した. Arm-ergometer, 坐位ergometerにて目標心拍数に達した例は, それぞれ, 13例中1例, 14例中2例のみであった. Arm-ergometerにおける心筋最高カウントに対する肺野の取り込みは37±9%であり, dipyridamole負荷(29±5%)よりも有意に高かった. これには胸筋への取り込みも含まれているものと思われる. Washout rateはdipyridamole負荷が45±9%, 坐位ergometerが46±12%であり, 同等の値を呈した. Dipyridamole負荷の心筋/background比は4.6±0.8であり, 2種のergometer(arm-ergometer;3.5±0.7, 坐位ergometer;4.2±0.9%)よりも有意に高く, 最も良好な画質を示した. 運動負荷が困難な症例に, dipyridamole負荷心筋シンチグラフィは有用であった. |

Abstract | [Summary]We assessed the usefulness of dipyridamole-thallium myocardial imaging in the patients unable to exercise adequately, comparing with arm-ergometer and standard (bicycle) ergometer. Fifty-six patients with arteriosclerosis obliterance, aortic aneurysm, aortic dissection and so on, who were revealed normal imaging, were studied. Only one of 13 cases with arm-ergometer and two of 14 with bicycle ergometer reached target heart rate. Lung thallium uptake in the cases with arm-ergometer (37+-9%) is higher than that with dipyridamole (29+-5%). This elevation may be confused with pectoralis muscle uptake. Washout rate is 45+-9% with dipyridamole and 46+-12% with bicycle ergometer, respectively, though there was no significant differences. Myocardial/background counts ratio with dipyridamole (4.6+-0.8%) is significantly higher than that with arm and bicycle ergometer (arm-ergometer; 3.5+-0.7, bicycle ergometer; 4.2+-0.9). Then, myocardial image with dipyridamole have superior quality. We concluded that dipyridamole-thallium myocardial imaging is very useful in the patients who have suboptimal exercise efforts. |
