Abstract | 「要旨」急性心筋梗塞を疑った36例で99mTc-PYP心筋シンチグラフィ (以下PYPスキャン) を施行する際, ファースト・パスを併用し心機能評価を行い, PYPスキャンの心筋摂取度, 梗塞サイズと比較した. PYPスキャンの心筋摂取度は左心機能を必ずしも示していなかった. 梗塞サイズと急性期の左室駆出率の比較は, 初発梗塞18例でR=-0.522, 再梗塞11例でR=-0.152であった. また初発梗塞と再梗塞を比較し, 急性期・慢性期ともに左室駆出率に有意差 (p<0.01) があり, 右室駆出率では有意の差がなかった. PYPスキャンにファースト・パスを併用すれば, 梗塞巣の検出に加え, 両心機能の計測を行うことができ, 急性心筋梗塞の病勢および予後の判定に有用であった. 本法はPYPスキャン施行時にファースト・パスを併用するだけの簡単な手技で急性期心機能評価を行うことができ, 今後活用されるべきである. |

Abstract | [Summary] This study was done to evaluate infarct size and ventricular function, simultaneously, in acute myocardial infarction by 99mTc-pyrophosphate scintigraphy (PYP scan) combined first pass method. Of 36 patients suspected of acute myocardial infarction, 29 patients showed positive uptake of 99mTc pyrophosphate, the sensitivity and specificity were 90.6 and 100%, respectively. Of positive 29 cases in acute myocardial infarction (AMI), initial and recurrent AMI was 18 and 11 cases, respectively. Correlation between infarct size by PYP scan and left ventricular ejection fraction (LVEF) was R = -0.522 in initial AMI and R = -0.152 in recurrent AMI, respectively. There was significant difference between LVEF in acute phase and that in chronic phase (P<0.01). Comparing acute phase with chronic phase, right ventricular ejection fraction (RVEF) and (LVEF) were improved in 6 of 11 cases and in 9 of 11 cases of intial AMI, respectively; those were improved in 3 of 6 cases and in 5 of 6 cases of recurrent AMI, respectively. 99mTc-pyrophosphate scintigraphy combined by first pass method could evaluate not only infarct size but also biventricular function of AMI. The assessment of severity of AMI by this combined method will tell prognosis of AMI. |
