Abstract | 「要旨」201Tl心筋シンチグラフィ, および心拍同期心プールイメージングを肥大型心筋症(HCM)24例, 正常対照群11例に施行した. HCMは心筋シンチ所見からI, Non-Obstructive, II, Obstructive, III. ASH, IV, APHの4型に分類した. またcircumferential profile法はそれぞれの心筋形態に特徴的なTlの摂取パターンを示した. 心拍同期心プールイメージングから心内腔の形態, 収縮期指標に加え拡張期指標として左室充満率(1/3FF)および左室平均充満速度(1/3FRm)を算出した. 前者はHCM各群と正常群間で差を認めなかったが後者はHCM各群とも小なる傾向があり, 1/3FRmはHCMの診断に有用となる可能性を示した. 両法の併用により, 非観血的にHCMの臨床的評価が行えることが示された. |

Abstract | [Summary]Tl-201 myocardial scintigraphy and gated cardiac blood pool imaging with Tc-99m were performed at rest in 24 hypertrophic cardiomyopathy (HCM) and 11 normal subjects. Based on visual analysis of Tl-201 myocardial scintigraphies, patients with HCM were subdivided into the following four groups; type I: non-obstructive, type II: obstructive, type III: asymmetric septal hypertrophy, type IV: apical hypertrophy. Characteristic myocardial hypertrophy of each group was also confirmed from the profile curves of circumferential analysis. First third filling fraction (1/3 FF) and mean first third filling rate (1/3 FRm) were obtained from gated cardiac blood pool imaging. As compaired with the normal subjects, 1/3 FF was not so sensitive for the detection of left ventricular hypertrophy. Mean +- S. D. of 1.3 FRm were 1.96 +- 0.56/sec (normal group), 1.30 +- 0.44/sec (type I), 1.18 +- 0.63/sec (type II), 1.17 +- 0.14/sec (type III), and 1.26 +- 0.03/sec (type IV). We considered that 1/3 FRm was a useful diastolic phase index in the diagnosis of HCM. |
