| Abstract | 「要旨」肥大型心筋症の心筋シンチグラフィーは, 壁肥厚, 取り込み増強のほか, 再分布を示すものがある. われわれは, 肥大型心筋症18名に運動負荷心筋シンチグラフィーを施行し, 取り込み低下を示した9名 (A群 ; ただし1名を除いて再分布を認めた) と, 取り込み低下を示さない9名 (B群) で, 再分布の臨床的意義を検討した. 指標として, (1) 胸痛の有無, (2) 胸部X線でのCTRおよび心電図 (VPCの有無も含める) , (3) 心エコー図, (4) トレッドミルおよびエルゴメーター負荷試験, (5) 心臓カテーテル検査の結果を用いた. 再分布を示す例では, 心エコー図での左室拡張末期径および左房径, 心臓カテーテル検査での肺動脈楔入圧および左室拡張末期圧, 運動負荷時のDouble productのいずれも高い傾向があったが有意差はなかった. 胸部X線でのCTRおよび心エコー図での心室中隔壁厚のみが, 再分布を示す例で有意に大きかった. 再分布領域は心室中隔に限らず, 前壁, 側壁, 下後壁にもみられた. |

| Abstract | [Summary] Using exercise myocardial scintigraphy, we had experienced some patients of hypertrophic cardiomyopathy (HCM) , who showed redistribution. To evaluate the clinical significance of the redistribution in HCM, we compared clinical and hemodynamic data of nine patients who showed redistribution (Group A) with those of nine patients who showed no hypoperfusion area (Group B) . One patient in Group A had low perfusion but no redistribution. CTR in Chest X-ray and IVS thickness in echocardiogram were significantly larger in Group A than Group B. (CTR : p<0.05, IVS thickness : p<0.01) Redistribution areas were not limited to hypertrophied anteroseptal wall, but it was found in other areas. The numbers of redistribution areas were 3 in anterior septum, 3 in anterior wall, 5in lateral wall, 3 in inferoposterior wall, and 1 in apex. Since myocardial degeneration and/or fibrosis is common in HCM, the hypoperfusion may be related to the myocardial degeneration or fibrosis. According to our study, redistribution seems to be related to the clinical findings of HCM : IVS thickness and CTR. And, the mechanism of redistribution in HCM is to be studied. |
