| Abstract | 「要旨」 有意冠動脈病変を有する29例に対し運動負荷RNVをPTCA施行前後で行い, PTCAの治療効果および再狭窄の検出に関し検討した. LVEFによる検討では再狭窄 (-) 群で有意な運動負荷時の左室機能の改善がみられ, 再狭窄検出に対するsensitivity, specificity, overall accuracyはそれぞれ100%, 68%, 79%であった. 左室局所壁運動による検討でも再狭窄 (-) 群ではPTCA前にみられた運動負荷時の壁運動の悪化が防止され, 再狭窄検出に対するsensitivity, specificity, overall accuracyはそれぞれ89%, 96%, 94%と良好であった. また左室容積による検討では, 運動負荷時のLVESVは再狭窄 (-) 群で減少傾向を示したのに対し再狭窄 (+) 群で有意に増加し, 収縮期血圧/LVESVの運動負荷による変化 (ERPV) でもPTCA前後の比でみると再狭窄 (-) 群で有意に高値を示し, 再狭窄検出の有用な指標となりうることが示唆された. |

| Abstract | [Summary] To evaluate late success of PTCA in 29 patients with coronary artery disease, exercise radionuclide ventriculography was performed. Twenty-nine patients were classified into two groups according to the presence of restenosis (Group N : 19 patients without restenosis, Group R : 10 patients with restenosis) . LVEF improved significantly in Group N, and the sensitivity, specificity and overall accuracy for detecting restenosis were 100%, 68% and 79%, respectively. Regional wall motion abnormality during exercise did not worsened in Group N, and the sensitivity, specificity and overall accuracy for detecting restenosis were 89%, 96% and 94%, respectively. The left ventricular end-systolic volume during exercise increased in group R but decreased in Group N. The exercise response of the ratio of systolic blood pressure to end-systolic volume in Group N was significantly larger than that of Group R, and was considered to be useful parameter for detecting restenosis. |
