| Abstract | 「要旨」PTCA施行後, 慢性期に多発する再狭窄を検出する上での負荷心筋シンチグラフィの有用性を検討した. 対象はPTCA後の経過観察期間中に再狭窄が臨床所見などから疑われた梗塞非合併労作性狭心症21例, 心筋梗塞症16例である. 負荷心筋シンチグラフィの再狭窄検出能はsensitivity, specificityともに胸痛や負荷心電図に比し優れており, また多枝病変では負荷心電図に比し再狭窄血管の部位の判定に優れていた. 再狭窄の判定はFILL INに基づく視覚的判定に加え, 再狭窄症例ではPTCA後に改善した%UPTAKE RATIOが再低下することで容易に行えた. 非再狭窄梗塞症例に時折見られた残存する再分布もPTCA後に%UPTAKE RATIOが経時的に改善することで再狭窄と鑑別可能であった. 負荷心筋シンチグラフィは再狭窄を早期かつ高精度に診断可能でPTCA後の症例の予後改善に極めて有用と考えられた. |

| Abstract | We studied the efficacy of stress thallium scan in detecting restenosis after primary successful PTCA. There were 21 patients with angina pectoris and 16 patients with previous myocardial infarction. The sensitivity and the specificity of stress thallium scan in detecting restenosis were superior to those of stress electrocardiography or chest pain complained in follow-up period. In multi-vessel disease, we could assess the vessel developing restenosis more easily than stress electrocardiography. Initial thallium %UPTAKE RATIO was significantly improved after PTCA but redecreased in patients developing restenosis. In patients showing residual redistribution despite of not developing restenosis, we could judge vessel patency by gradually improving initial %UPTAKE RATIO after PTCA. Thus, stress thallium scan proved to be useful in detecting restenosis after PTCA. |
