This study compares exercise radionuclide ventriculography (RNVG) and exercise myocardial scintigraphy with 201Tl (MSC) both computed trisectorially. 137 patients before and after transluminal angioplasty (TCA) were investigated. While specificity equivalent was set at 90% for both methods (10% percentile of the controls [n = 29]) overall sensitivity for RNVG was 79% (n = 86) and for MSC 78% (n = 98). Sensitivity of RNVG for lesions of the posterior wall was lower than for the anterior wall: LAD stenoses 83% (n = 46), RCA stenoses 71% (n = 17), and LCX stenoses 63% (n = 8). Sensitivity of MSC presents only a slight difference between anterior and posterior wall lesions: LAD stenoses 78% (n = 51), RCA stenoses 73% (n = 22), RCX stenoses 100% (n = 8). Reproducibility of pathological findings before and after non-successful TCA and the determination of the stenosed vessel was slightly better with MSC than with RNVG. Functional improvement after a successful TCA is predictable by MSC, whereas RNVG documents the functional improvement.
本研究比较了运动放射性核素心室造影（RNVG）和用201铊进行的运动心肌闪烁扫描（MSC），两者均采用计算机三分量法。对137例经皮腔内血管成形术（TCA）前后的患者进行了研究。两种方法的特异性等效值均设定为90%（对照组[n = 29]的第10百分位数），RNVG的总体敏感性为79%（n = 86），MSC为78%（n = 98）。RNVG对后壁病变的敏感性低于前壁：左前降支狭窄为83%（n = 46），右冠状动脉狭窄为71%（n = 17），左旋支狭窄为63%（n = 8）。MSC对前壁和后壁病变的敏感性仅存在轻微差异：左前降支狭窄为78%（n = 51），右冠状动脉狭窄为73%（n = 22），左旋支狭窄为100%（n = 8）。对于未成功进行TCA前后的病理结果及狭窄血管的判定，MSC的可重复性略优于RNVG。成功进行TCA后的功能改善可通过MSC预测，而RNVG可记录功能改善情况。
