| Abstract | 「要旨」冠動脈疾患で冠血行再建術を施行した症例を対象に術前後にジピリダモール負荷99mTc-tetrofosmin心筋シンチグラフィを施行し, 術前の安静時像が術後の予測に役立つか否か, また視覚的なSPECTの読影について検討した. 狭心症9例は術後の安静時像で術前に比較し心筋集積の改善が全例にみられ, かつ正常化したものが5症例であった. 術前に心筋viabilityがないと考えられた陳旧性心筋梗塞でかつ瘢痕化した症例であっても, 50%(4/8)で心筋集積の改善がみられた. 陳旧性心筋梗塞兼狭心症5症例においても全例で心筋集積の改善が見られた. 狭心症を伴う症例では術前の安静時像で不完全なfill-inが多いためと考えられた. 陳旧性心筋梗塞における瘢痕化症例の心筋集積の改善は冬眠心筋の存在のためと考えられるが, これらの心筋を正しく検出することは99mTc-tetrofosminの安静時像であっても困難と考えられた. |

| Abstract | [Summary]Dipyridamole-loading 99mTc-tetrofosmin myocardial scintigraphy was performed for patients with coronary artery disease who underwent percutaneous transluminal coronary angioplasty(PTCA)in order to examine whether SPECT imaging prior to treatment is useful for the determination of prognosis after coronary intervention. Thirty-six patients including 9 with angina pectoris(AP), 22 with old myocardial infarction(OMI)and 5 OMI with AP were underwent dipyridamole-loading 99mTc-tetrofosmin myocardial SPECT before and after coronary intervention. The length of follow-up was 185+-107 days after PTCA. Improvement of myocardial uptake was observed on myocardial SPECT in all cases with AP. Improvement of the myocardial uptake was observed 50%(4/8)of patients with OMI who had no myocardial viability. It was suggested that the improvement of myocardial uptake after PTCA was due to incomplete fill-in in cases with AP and that the presence of fill-in was important for level of fill-in in patients with AP. The improvement of myocardial uptake in the scar tissue in patients with OMI contributed to the hibernating myocardium. We concluded that correct detection of hibernating myocardium was difficult despite the superior imaging capability of 99mTc-tetrofosmin myocardial SPECT. |
