高龄急性心肌梗死患者临床特征及直接冠状动脉介入治疗的疗效评价

目的分析高龄ST段抬高型急性心肌梗死（STEMI）患者临床特征及评价直接冠状动脉介入治疗（直接PCI）的疗效。方法选择直接行PCI治疗STEM／患者121例，75岁以上47例为高龄组，同期60-74岁74例为对照组。观察两组患者临床特征、直接PCI术成功率、心电图ST段回落、心绞痛改善、住院期间主要不良心脏事件（MACE）发生率。结果高龄组、对照组直接PCI术后即刻成功率分别为97．87％、97．30％，术后2h心电图ST段回落≥150％分别为78．72％、72．92％，术后心绞痛明显改善率分别为88．11％、86．49％，住院期间MACE发生率分别为2．12％、2．70％；两组以上观察指标比较差异无统计学意义。结论STEMA急性闭塞病变行直接PCI治疗时植入支架近期临床疗效显著，且成功率及安全性均较高。

Clinical feature of the older patients with acute myocardial infarction and effect evaluation of primary coronary intervention

Objective To analyze the clinical feature of older patients with AMI and to assess the curative effect of primary PCI.Methods Forty-seven patients over 75 with ST-segment elevation myocardial infarction who had undergone primary PCI were chosen as elders group,74 patients who range from 60 to 74 years old underwent primary PCI were chosen as control group.Some indexes were observed as followed:the differences of clinical feature,the success rate of primary PCI,TIMI blood flow after primary PCI,the resolutio...
