| Abstract | 「要旨」PTCA後の201Tl運動負荷心筋SPECTにおける逆再分布現象の臨床的意義を明らかにするために, PTCA 1週後および3〜6か月後の遠隔期にSPECTを施行し得た症例で検討した. 逆再分布現象は1週後では8/54例に, 遠隔期には5/38例に認められた. 逆再分布現象が出現した症例では, 左室造影にて当該部位にいずれも軽度の壁運動異常を認め, PTCA後の冠動脈狭窄度は逆再分布現象を認めない症例に比し有意(p<0.05)に少なかった. すなわち, 逆再分布現象は軽度の心筋障害が存在する部位にPTCAにより十分な冠血流量が得られた場合に出現するものと考えられた. しかし, 再狭窄がないのに遠隔期で消失したものや, 冠狭窄の有意な変化がないのに新たに出現したものは, こうした心筋障害と冠血流量の関係のみでは説明できず, PTCA後のcoronary flow reserve, stunned myocardium, hibernating myocardium等の他の要因の関与が推察された. |

| Abstract | [Summary] Clinical significance of reverse redistribution on thallium image was evaluated in 54 patients who had undergone PTCA. Thallium SPECT imaging was performed one week and three to six months after PTCA. Reverse redistribution was detected eight of 54 patients one week after PTCA and five of 38 patients three to six months after PTCA. In the segments with reverse redistribution, reduced regional wall motion and lesser degree of coronary stenosis was common features (p<0.05) angiography. In conclusion, reverse redistribution had a tendency to appear in the region with mild myocardial injury and relatively high coronary blood flow after PTCA. But in cases with new occurrence and disappearance of reverse redistribution during follow up period, we can not assess the factors to explain these phenomena. In these segments, "coronary flow reserve", "stunned myocardium", "hibernating myocardium" or other factors may be related. |
