| Abstract | 「要旨」急性下壁心筋梗塞の診断で入院し, 201TlCl・99mTc-PYP2核種SPECT(dual-nuclide SPECT, D-SPECT)を施行した症例を対象に, 右室に99mTc-PYPの取り込みを認めた例(PYP(+)群)と認めない例(PYP(-)群)の臨床像を対比検討した. 冠危険因子, 狭心症歴, 入院時血圧・心拍数・血行動態に群差はみられなかった. 発症から入院までの時間はPYP(+)群で有意に長く, 急性期に冠動脈再疎通療法を施行された例が少なかった. PYP(+)群の8例中7例でD-SPECT後に初めて右室梗塞と診断された. PYP(+)群は3病日以内にショックをきたす頻度が高く, 入院期間も長かった. 冠動脈造影所見より推定した責任冠動脈病変部位は, PYP(+)群の50%が右室枝より近位部であったが, PYP(-)群では18%に過ぎなかった. D-SPECTは下壁梗塞に合併する右室梗塞の診断にきわめて有用であり, 発症早期の施行によりショックの予防に貢献する可能性が示唆された. |

| Abstract | [Summary] We evaluated clinical significance of dual-nuclide SPECT imaging (D-SPECT) of thallium- 201 and technetium-99m pyrophosphate (PYP) in patients of acute inferior left ventricular infarction with PYP uptake in the right ventricle (PYP (+) group) in comparison with those without PYP uptake (PYP (-) group). There was no difference in coronary risk factors, history of angina, blood pressure, heart rate, and hemodynamics on admission between PYP (+) group and PYP (-) group. The duration from onset to admission was longer in PYP (-) group and coronary reperfusion therapies were carried out in few cases. In 7 of 8 PYP-positive patients, the diagnosis of right ventricular infarction was made only by D-SPECT. Four of 8 were complicated with shock within three days, and the duration of hospitalization was longer. Coronary angiography demonstrated many proximal lesions (50%) in PYP (+) group but few ones (18%) in PYP (-) group. D-SPECT was very useful for diagnosing acute right ventricular infarction, and it might contribute to the prevention of shock if performed within a few days. |
