Data about the primary success and complication rates following transluminal coronary angioplasty are comparable worldwide. Reports on the frequency of recurrences, however, differ considerably. Data concerning factors enhancing the risk of restenosis are contradictory. We compared a group of 62 patients with angiographically confirmed restenosis with a group of 62 patients without restenosis. There were no significant differences with regard to age, sex, onset of symptoms and severity of angina pectoris, number of previous infarctions, incidence of multivessel disease, maximum size of the balloon catheters used and primary dilatation results. The following factors were significantly associated with the occurrence of restenosis: high-grade stenoses prior to dilatation, stenoses involving long segments of coronary arteries, eccentric stenoses, the necessity to apply high balloon pressures, long duration of balloon inflation, and also the patient being overweight, a nonsmoker and having undergone an alteration in continuous treatment.
经皮腔内冠状动脉成形术后的初次成功率和并发症发生率在全球范围内具有可比性。然而，关于复发频率的报告差异很大。有关增加再狭窄风险因素的数据相互矛盾。我们将一组62例经血管造影证实有再狭窄的患者与一组62例无再狭窄的患者进行了比较。在年龄、性别、症状发作和心绞痛严重程度、既往梗死次数、多支血管病变发生率、所用球囊导管的最大尺寸以及初次扩张结果方面，两组之间没有显著差异。以下因素与再狭窄的发生显著相关：扩张前的高度狭窄、累及冠状动脉长节段的狭窄、偏心狭窄、需要应用高球囊压力、球囊膨胀持续时间长，以及患者超重、不吸烟和持续治疗发生改变。
