摘　　要：用潘生丁核素心肌断层显像随访３０例由经皮冠状动脉腔内成形术（ＰＴＣＡ）治疗的冠心病患者，９７．８％术前心肌显像呈缺血表现的室壁节段在术后缺血消失或改善，而术前心肌显像仅表现为梗塞的节段术后无变化．术后１个月３０例患者治疗有效率为７６．７％，在术前心肌显像有缺血改变的２４例患者治疗有效率为９５．８％．半年复查治疗有效率分别为６６．７％及８３．３％．半年内１２．５％病例心肌显像发生再缺血并经冠状动脉造影证实．表明此法可以作为ＰＴＣＡ后短、长期疗效的评价手段，为ＰＴＣＡ选择合适的病例及合适的病变血管．Abstract To evaluate the effect of coronary angioplasty in patients with coronary artery disease, we performed dipyridamole 99mTc myocardial imaging pre-and post-angioplasty. Within one month, 97.8%myocardial segments showing redistribution before angioplasty became normal or improved after angioplasty, but none improved in segments showing“fixed”defect only. Within one month, effective rate of treatment was 76.7% in 30 patients but 95.8% in 24 patients showing redistribution before angioplasty. Follow-up study within 6 months showed that the effective rate of treatment was 66.7%in 30 patients and 83.3% in 24 patients respectively. The myocardial imagings of three patients kept normal during one year follow-up. In 12.5% cases, the myocardial imaging showed reischemia which was confirmed by angiography.
