急诊介入与择期介入对左室急性心肌梗死治疗的影响分析

Analysis of the effect of emergency and selective percutaneous coronary intervention on the treatment of acute left ventricular myocardial infarction

目的探讨急诊介入与择期介入对左室急性心肌梗死治疗的影响。方法选取86例左室急性心肌梗死患者,根据患者出现相应临床症状到行经皮冠脉介入治疗(PCI)的时间分为急诊组(n=29)、延迟1组(n=27)及延迟2组(n=30),测定住院期间及治疗后6个月的左室射血分数(LVEF)及左室舒张末期内径(LVEDD)。结果急诊及延迟1组LVEF及LVEDD改善明显,差异有统计学意义(P<0.05),而延迟2组改善无明显差异。结论左室急性心肌梗死的急诊介入及2周前延迟介入对心脏功能均有所改善。

Objective To investigate the effect of emergency and selective percutaneous coronary interven -tion in the treatment of acute left ventricular myocardial infarction .Methods Eighty-six patients with acute left ven-tricular myocardial infarction were selected in our hospital and divided into the emergency group （ n =29 ） , delay group 1（n=27） and delay group 2（n=30）.The LVEF and LVEDD were measured at the time of hospitalization and 6 months after treatment.Results In the emergency group and delay group 1,LVEF and LVEDD improved signifi-cantly, the difference was statistically significant （P〈0.05）, but there were no significant difference in LVEF and LVEDD in delay groups 2.Conclusion Emergency PCI and 2 weeks-delayed PCI in the treatment of acute left ven-tricular myocardial infarction can improve cardiac function .
