| Abstract | 「要旨」左室肥大を有する圧負荷群12例, 容量負荷群14例, 特発性心筋症14例 (HCM : 8例, CCM : 6例) に201Tl心筋シンチグラフィーを行い, LV area (左心領域) , LV uptake index (左心摂取率) , Wall uptake ratio (左心壁摂取率) の3指標を算出し, VCG, UCGの各計測値と比較検討した, 1) 圧負荷群, 容量負荷群とも3指標は対照群より有意に大で, LV areaは後者で有意に大であった. 2) LV area, LV uptake indexの2指標はVCG, UCGの各計測値と良い相関を認めた. 3) HCMでは3指標, CCMではWall uptake ratioを除く2指標が対照群より有意に大で, LV areaはCCMで, Wall uptake ratioはHCMで有意に大であった. さらに, 肥大型ではconcentric hypertrophyにより左室腔が狭小化すると同時に, 肥大によりLV uptake index, Wall uptake ratioも増加し, うっ血型では左室腔の拡大に伴い, 左室壁厚はうすくなるが, LV areaは増大し, 全体の心筋量は増大の傾向がみられた (eccentric hypertrophy) . |

| Abstract | [Summary] Thallium-201 (201Tl) myocardial scintigraphy was performed in 40 patients with left ventricular hypertrophy (LVH) . Twelve out of 40 patients had pressure overloading (Aortic stenosis : 5, Hypertension : 7) , 14 patients had volume overloading (Aortic regurgitation : 9, Mitral regurgitation : 5) and 14 had idiopathic cardiomyopathy (Hypertrophic type (HCM) : 8, Congestive type (CCM) : 6) , respectively. LV area, LV uptake index and Wall uptake ratio were calculated from left anterior oblique view of 201Tl myocardial images. These three indices of both pressure overloading and volume overloading were significantly higher than those of controls. The degree of LVH was indicated by both LV area and LV uptake index. LV area was significantly larger in volume overloading than in pressure overloading. In idiopathic cardiomyopathy, these three indices of HCM and LV area and LV uptake index of CCM were significantly increased compared with those of controls. LV area of CCM was significantly larger than that of HCM, while Wall uptake ratio of HCM was significantly higher than that of CCM. LV uptake index and Wall uptake ratio of HCM became higher according as left ventricular cavity became smaller. LV area of CCM became larger in proportion as left ventricular cavity became larger and as left ventricular wall thickness became thinner. |
