老年冠心病患者冠状动脉介入治疗术的临床评价

目的 评估本院75岁以上冠心病患者接受冠状动脉介入治疗术(PCI)的安全性和临床疗效.方法 对医院自2007年12月至2010年8月共60例年龄≥75岁的冠心病患者临床特点、冠脉病变特点、PCI成功率、手术并发症进行回顾性分析,并与94例<75岁患者作比较.结果 ≥75岁老年组患者中,陈旧性心肌梗死、左心功能减退及肾功能减退的比例均明显高于<75岁年龄组,两组比较,差异有统计学意义(χ2分别=4.14、10.75、4.47,P均＜0.05);≥75岁老年组患者的冠脉病变多为多支病变,病变类型多为复杂病变,和<75岁年龄组比较,差异均有统计学意义(χ2分别=3.95、4.52,P均＜0.05);成功置入支架的比例比较,≥75岁老年组明显低于<75岁年龄组,分别为88.33%与96.81%,两者的差异有统计学意义(χ2=4.25,P＜0.05); PCI术中术后发生的并发症比例,≥75岁老年组13.33%,而<75岁年龄组4.25%两者比较,差异有统计学意义(χ2=4.25,P＜0.05);高龄组中住院期间总死亡率10.00%.非高龄组总死亡率1.06%,两组比较,差异有统计学意义 (χ2=4.84,P＜0.05).结论 高龄因素对冠心病患者选择性冠状动脉介入治疗术成功率和安全性有明显的影响.
