摘要(Abstract)：
目的比较单个短和长支架及多个支架置入的远期血管造影再狭窄发生率。方法回顾性分析１９９６年５月至１９９８年１０月在我院接受冠状动脉内支架置入并有血管造影随访的７７例病人的临床及血管造影资料。单个短支架组（Ａ组：支架长度≤２０ｍｍ）３７例，３９支血管；单个长支架组（Ｂ组：支架长度＞２０ｍｍ）２２例，２５支血管；多个支架组（Ｃ组）１８例，１８支血管置入３９个支架。结果病变长度在Ｂ和Ｃ组明显长于Ａ组［（２３．６６±１２．７８）ｍｍ和（２６．４２±１３．６０）ｍｍ与（１０．３０±４．６７）ｍｍ，Ｐ＜０．００１］；支架长度Ｃ组＞Ｅ组＞Ａ组，Ｐ＜０．００１和０．００２。随访时最小管腔开放直径（ＭＬＤ）和管腔晚期丢失在Ａ和Ｃ组间有明显差异，Ｐ＜０．０１和０．０２，而在Ａ和Ｂ组，Ｂ和Ｃ组间无统计学差异。三组的再狭窄率分别为 ２８．２％、３６％和 ６１．１％，Ｃ组明显高于 Ａ组（Ｐ＜ ０．０５），而 Ｂ组又高与 Ａ组、Ｃ组高于Ｂ组的趋势，但统计学上无明显差异。Ｌｏｇｉｓｔｉｃ多因素回归分析证实多个支架置入是再狭窄的唯一的独立预测因素（ＯＲ＝３．２９，Ｐ＜０．０５）。结论多个冠状动脉内支架置入是发生晚期血管再狭窄的唯一独立预测因素；而?
