| Abstract | 「要旨」マルチゲート心血液プール像の左室全体, および画素ごとの容量曲線をフーリエ高次項にて近似し, 正常群14例, 肥大心群28例 (HCM 9例, HOCM 7例, HT 12例) , IHD群37例の合計79例の収縮期, 拡張期機能を検討した. 左室全体の指標として駆出率 (EF) , 収縮末期までの時間 (TES) , 最大駆出速度 (PER) , それまでの時間 (TPE) , 最大充満速度 (PFR) , それまでの時間 (TPF) を求めた. さらに左室内のTES, TPE, TPFの各位相分布ヒストグラムの標準偏差 (SD) を左室asynchronyの指標とした. 収縮期指標TPEはHCM, HOCMではHTより短縮傾向を示した. 拡張期指標TPFは肥大心, IHD群ともに延長し, PFRはIHD群で低値を示し拡張期障害を示した. 拡張期asynchronyの指標TPF (SD) はIHD群およびHCM, HOCMで高値となり, asynchronous relaxationの存在が示唆された. このようにフーリエ高次項近似は肥大心, IHDの左室全体および局所の収縮期, 拡張期の評価に有用であった. |

| Abstract | [Summary] Fourier analysis of gated blood-pool images using higher-order harmonics was performed in 79 cases to evaluate global and regional cardiac performance. Following indexes were obtained: EF (ejection fraction) , TES (time to endsystole) , PER (peak ejection rate) , TPE (time to PER) , PFR (peak filling rate) , TPF (time to PFR) , PFR/PER, TPF/TPE, TES (SD) , TPE (SD) , TPF (SD) . Patients with ischemic heart disease (IHD) showed significantly lower PFR, longer TPF, and lower tendency of PER than normal group. Patients with hypertrophic heart disease (HCM: Hypertrophic cardiomyopathy, HOCM: Hypertrophic obstructive cardiomyopathy, HT: Hypertension with left ventricular hypertrophy) showed significantly longer TPF, and higher PER than normal group. Patients with HCM and HOCM showed shorter TPE than HT, probably due to difference of afterload. Patients with IHD, HCM, and HOCM showed significantly higher TPF (SD) than normal group, suggesting asynchronous relaxation. However, patients with HT showed normal TPF (SD) . We conclude that Fourier analysis of gated blood-pool images using higher-order harmonics provides useful informations of systolic and diastolic properties in ischemic and hypertrophic heart diseases. |
