摘要(Abstract)：
目的 评价冠状动脉开口处病变冠心病患者支架术的疗效。方法 1999年 7月至 2 0 0 0年 12月连续 5 0 2例冠心病患者行选择性冠状动脉内支架术 ,其中 5 6例行开口处病变支架术 (甲组 ) ,4 4 6例行非开口处病变支架术 (乙组 ) ,比较两组手术成功率及随访结果。结果 甲组中 5 4例支架术成功 (96 4 % ) ,并发症发生率 3 6 % ;乙组中 4 32例支架术成功 (96 9% ) ,并发症发生率 7 2 % ,两组差异均无显著性 (P均 >0 0 5 )。随访 (12 0± 4 8)个月 ,随访率为 92 3%。甲乙两组的心绞痛复发(5 0 0 %和 4 4 4 % ) ,硝酸酯药物停用 (2 6 9%和 35 2 % ) ,再入院 (44 2 %和 31 9% )及心功能改善(42 3%和 5 1 4 % )差异也无显著意义 (P均 >0 0 5 )。但甲组心脏事件发生率较乙组显著增加 (34 6 %和 2 0 4 % ,P =0 0 2 0 )。结论 开口处病变患者冠状动脉内支架术安全、成功率高 ,但预后较非开口处病变患者差。
