Abstract「要旨」拡張型心筋症60症例に心筋シンチグラフィを施行, 灌流欠損の出現様式から, 1)左室の拡大のみ有する16症例(I群), 2)心尖部の灌流低下を有する12症例(II群), 3)心尖部から下後壁にかけて灌流欠損を有する32症例(III群)の3群に分けることができた. また経年変化を観察した16症例にて, 灌流欠損は心尖部から下後壁, 次いで中隔に拡がることが示された. また, 本症の心筋シンチグラムの分類と臨床症状, 心カテーテル検査などとの対比を行った. この結果, I群からIII群になるに従い, 臨床症状の増悪, 心機能の低下を伴い, 本分類が, 本症の重症度評価とよく一致することが確かめられた. 拡張型心筋症において, 心筋灌流欠損の出現は一定の進展様式を有し, 本症の重症度評価に有用であった.

AbstractIn order to assess the severity of dilated cardiomyopathy, thallium scan was performed in 60 cases. In 16 of all, serial thallium scan was performed in the periods of average 26 months. In these cases, extension of perfusion defect was observed from apical to inferoposterior regions. Therefore, we classified dilated cardiomyopathy into three groups by thallium scan; (1) dilated left ventricular type (n=16), (II) apical hypoperfusion type (n=12), (III) inferoposterior perfusion defect type (n=32). These groups were correlated with hemodynamic findings. All patients had also cardiac catheterization and gated blood pool scan. As results, group III had high incidence of right ventricular and lung thallium uptake and patchy pattern compared to other groups. Group III had also high incidence of dyspnoea on exertion, S3 and ECG abnormalities. In hemodynamics, end-diastolic ventricular volume index and endsystolic ventricular volume index increased and, right ventricular ejection fraction and left ventricular ejection fraction decreased according to the severity of dilated cardiomyopathy from group I to III. In addition, the incidence of mitral regurgitation and dyskinesis was observed highly in group III. In conclusion, perfusion defect was frequently demonstrated in dilated cardiomyopathy without coronary artery stenosis. And right and left ventricular function was depressed according to the extension of perfusion defect.
