Coronary angiography in a 55-year-old man with coronary heart disease and typical physical activity-induced angina revealed a subtotal stenosis in the middle third of the right coronary artery while left ventricular function was normal. Percutaneous transluminal coronary angioplasty (PTCA) was performed in January 1989, achieving a residual stenosis of less than 50%. However, restenosis of more than 90% developed within six months, necessitating another PTCA, followed immediately by implantation of a metal (Palmaz-Schatz) stent in the stenotic area. No stenosis was demonstrable afterwards. Maintenance medication with anticoagulants (phenprocoumon) and platelet-function inhibitors (aspirin and dipyridamole) was instituted and repeat angiography three months later demonstrated good dilatation results without any restenosis.
一名55岁患有冠心病且有典型体力活动诱发型心绞痛的男性，冠状动脉造影显示右冠状动脉中三分之一处有次全狭窄，而左心室功能正常。1989年1月进行了经皮腔内冠状动脉成形术（PTCA），残余狭窄小于50%。然而，六个月内出现了超过90%的再狭窄，需要再次进行PTCA，随后立即在狭窄区域植入金属（Palmaz-Schatz）支架。此后未发现狭窄。开始使用抗凝剂（苯丙香豆素）和血小板功能抑制剂（阿司匹林和双嘧达莫）进行维持治疗，三个月后重复血管造影显示扩张效果良好，无任何再狭窄。
